Definitions

  • the present invention relates to devices making it possible to deposit labels, generally self-adhesive, on at least one face of a box, for example the identification labels of medicaments packaged in boxes of parallelepiped shape, and more particularly devices operating in automatic mode.
  • the automatic label dispensing machines developed to date can only carry out labeling if the boxes are running one behind the other, being regularly separated from each other by a space of a determined value.
  • the time taken by a box to traverse this space thus makes it possible to carry out a certain number of operations, for example the verification of the presence, for example on a support strip serving as a reserve of labels, of a label to be deposited.
  • the object of the present invention is to provide a device for applying labels to boxes, having a higher yield than that of the known devices of the prior art, of a simple structure, not very complicated to implement, and ensuring a total security in applying these labels.
  • the subject of the present invention is a device for depositing labels distributed regularly over a strip, on a first face of substantially parallelepiped boxes, the distance separating two second and third faces laterally bordering said first face being the same for all said boxes, characterized in that it comprises: means for animating said boxes with a substantially uniform translational movement on a movement path in such a way that said first face of said boxes is parallel to said movement path and at a determined level, and that said second and third faces make an angle not zero with the direction of said displacement path, said second face being, in the direction of translation, forward relative to said third face, first means capable of delivering a first signal for recognizing the presence of the second face of a box when a point on the first face of said box is located in a predetermined position, on said determined level, second means capable of delivering a second detection signal to discriminate whether or not the third face of a first box is in contact with the second face of a second box following the first, when said second face of this first box is capable of being detected by said first
  • the device according to the invention makes it possible to place labels like vignettes on one face of boxes 1, 2, ... which are substantially parallelepipedic and whose two faces 50, 51 laterally bordering that 4 on which a label is to be placed are separated from a distance which is the same for all the boxes of the same series.
  • boxes 1, 2, ... are substantially parallelepipedic and whose two faces 50, 51 laterally bordering that 4 on which a label is to be placed are separated from a distance which is the same for all the boxes of the same series.
  • These boxes are, for example, packaging for medicines and the labels are those allowing the identification of these medicines, for example for certain administrative operations.
  • the device comprises means for animating the boxes 1, 2, ... with a substantially uniform translational movement on a movement path 3 so that the face 4 of each box on which the label is to be placed , here called “the first face”, ie parallel to the displacement path 3 and to a determined level 5 which will be the level at which the labels will be applied, the direction of the displacement path making a non-zero angle with the two faces 50 , 51 laterally bordering the first face 4.
  • the means for animating the boxes in translation are for example constituted by guide rails 6, 7, ... bordered on each side by lateral conveyor belts 8, 9 driven by a uniform translational movement, for example endless around axes 10, 11, ... substantially perpendicular to the guide plane 12, on which the boxes 1, 2, ... slide by friction.
  • the device can be used for boxes of all sizes.
  • the two conveyor belts 8, 9 are advantageously mounted on means making it possible to adjust the distance separating them, as well as possibly their level, the distance separating them being substantially equal to the length 14 of the boxes, this is i.e. the distance separating the two faces laterally bordering the first face and being parallel to the path of displacement.
  • the boxes are thus pinched between the two conveyor belts which drive them in translation on the travel path 3.
  • the guide rails 6, 7, ... are mounted, for example, on slides making it possible to adjust, on the one hand, their position relative to the reference level 5 defined above, as a function of the height of the boxes and, on the other hand, their spacing, as a function of the length 14 of the boxes.
  • the means for moving the boxes in translation bring them to the entrance of a corridor 15 on the rails 6, 7, ... formed between the two conveyor belts, the end of these two belts forming a funnel.
  • the two conveyor belts pinch each box by the two faces 16, 17 distant from the length 14 of the box.
  • the boxes thus pinched are translated along the path of movement 3 and, as they are placed on the rails 6, 7, ... prepositioned according to the height 13 of the boxes, they move by automatically presenting their first face 4 at level 5 where the labels must be applied.
  • the device also comprises means for controlling the removal of a label from a given point on a given surface, and at a given instant, when the given point is located at a given level, in fact level 5 previously defined.
  • these means consist of a support strip 20 on which are arranged the labels 21 to be placed on the boxes.
  • These labels are, for example, of the self-adhesive type and the support strip is for example made of a plasticized paper making it possible to maintain them, but also to peel them off easily, without however making them lose their self-adhesive power.
  • This strip 20 supporting the labels 21 regularly spaced by a given pitch is wound on a transmitting coil 22 which can be unwound by pivoting around a rotation shaft 23 generally located at a level 24 higher than that, 5, of the placement of the labels.
  • the device comprises a pad forming a corner 25 at an acute angle, the point 26 of which is situated above, but very close to, the laying level 5, the two surfaces 27, 28 defining this corner 25 being both located above this level 5, to allow the sliding of the support strip 20.
  • the strip is positioned on this pad so that the labels are located on the face 29 of the strip opposite to that 30 which comes to the contact of the corner and which slides on the two faces 27, 28 of this corner.
  • the strip After going around this corner by marrying the acute end 26, the strip is taken up by a take-up reel 31 which can take it up after the labels have been placed on the first face 4 of the boxes, as explained below.
  • the device therefore also includes means for controlling the unwinding and advancement of the support strip on the corner 25.
  • These means include in particular, in the example illustrated, a controllable stepping drive motor 32 allowing rotation of the take-up reel 31 around its rotation shaft 33. This motor is controlled by an order depending on its nature, generally electric, applied to its control input 34.
  • the take-up reel 31 exerts a force of traction on the strip 20 to drive the unwinding movement of the transmitting coil 22 on which a braking force can possibly be exerted, making it possible to obtain a perfectly stretched support strip over its entire "V" shaped path on each side of the corner 25, one of the branches of the "V” being defined by the part 35 of the support strip still bearing the labels, the other being defined by the part 36 of the strip from which the labels have been peeled off.
  • the folding force exerted on the strip with respect to a certain rigidity of the label causes the front portion 40 of this label to come off. This continues to peel off as the support strip unrolls and folds over the end 26 of the corner. Furthermore, as soon as the front part 40 of the label begins to peel off from the support strip, it is pressed against the first face 4 of the box, at level 5 defined above and at a given point, and continues to be placed there as it comes off the support strip and the box advances on the path of movement 3.
  • the device advantageously comprises a pressure roller 41 whose action surface 42 passes over the face 4, at level 5, this roller being driven in rotation by the movement of the boxes on the movement path.
  • the end 40 of the labels is introduced automatically between the face 4 of the boxes and the surface 42 of the pressure roller 41, being pressed against this face, for example under the action of springs 43 schematically represented acting, for example, on the bearings 44 for holding the shaft 45 for rotation of this pressure roller 41.
  • the device includes means for controlling this installation according to the advance of the boxes along the travel path 3.
  • the boxes that are used are of rectangular shape, and therefore that their first face 4 is bordered laterally by a second face 50 and a third 51 which are perpendicular thereto, the distance separating these two faces 50 and 51, respectively called “front” and “rear” in the direction of movement, being the same for all the boxes of the same series. This distance will conventionally be referred to here as the width of the boxes.
  • the latter comprises first means 52 capable of producing at output a first signal when the front face 50 is at a determined location on the path of movement 3.
  • This position corresponds to the location of a box on the travel path, at the instant of the first signal, such that the first face 4 of this box has a given point, that chosen for the start of fitting the label, capable of coming into contact with the front end 40 of the first label 21 ready to be applied, this label being, for the rest, still affixed to the support strip 20.
  • an order given on the control input 34 of the stepping motor 32 triggers the unwinding of the support strip.
  • the speed of this unwinding is synchronized with that of the translational movement of the box, which allows the label to be applied uniformly, allowing it to be bonded over its entire surface.
  • the order given on the control input of the stepping motor 32 is supplied by a processing member 58 based, for example, on a microprocessor.
  • Figures 1 and 2 illustrate an embodiment of the first means 52 for detecting the presence of a front face 50. It consists of an emitting source 53, for example a light emitting diode, attached to a photosensitive receiver 54.
  • the emitting source 53 emits a light beam which, when the corner 55 of the front face 50 enters it, is diffracted to return a quantity of light sufficient to impress the photosensitive detector 54.
  • the latter then delivers at output 56, a signal whose variation of emission is interpreted as detecting the presence, at the instant of this emission, of the corner 55 of a front face 50 opposite this transmitter-receiver couple 53-54.
  • This signal delivered to the output 56 is then sent to the input 57 of the processing unit 58 mentioned above, and the functions of which will be explained below, among which: the control of the stepping motor for bonding a label in the desired location on the first side 4 of this box 2.
  • the instant when the front face 50 of a box is at a given location on the movement path 3 determines the moment of application of the label allocated to this box.
  • these means for detecting the front face 50 are adjustable in position XY, and in particular according to a parallel to the direction of the travel path 3.
  • the transmitter-receiver couple 53-54 is for example arranged on a carriage 59 movable along at least one component parallel to the direction of the travel path 3 of the boxes 1, 2, ... , so as to be able to adjust the position of the point where the corner 55 of the front face 50 of each box must be located, at the time when the placing of a label must be ordered.
  • the first detection means 52 defined above give the desired result when the front face 50 of a box is clearly determinable, that is to say when it is well offset from the rear face 51 of the box which precedes it .
  • the device comprises second detection means 60 located upstream of the first means 52, taking as direction that of the displacement of the boxes.
  • These second detection means 60 are capable of delivering at output 61 a signal determining the presence of a rear face 51 situated opposite these second means 60 and not attached to the front face of the next box. The absence of such a signal delivered by the second detection means makes it possible to deduce that the rear face 51 of the box 2 whose front face 50 has been detected by the first means 52 is in contact with the front face of the next box 1.
  • the first means 52 deliver at their output 56 a signal determining the presence of a front face 50 and the second means 60 deliver a signal representative of an absence of rear face, makes it possible to deduce that a box is in contact with the box which precedes it and which has enabled the delivery of the signal determining the presence of a front face opposite the first means 52.
  • the processing circuit 58 can develop, synchronously with the movement of these boxes, a signal for controlling the advance of a label at the end 26 of the corner 25 for install it as described above. Indeed, taking as a point of time origin that of the detection of the first detectable front face 50 passing opposite the first detection means 52, in the case where the second detection means 60 do not emit a signal for recognizing the rear face of the box, the front face of which has been detected, it is possible to trigger, after the automatic placing of a label on the box, the front face 50 of which has been detected, the laying of a new label on the following box , the two label laying orders being separated by a time equal to "l / v", where "l” is the width separating the two second 50 and third 51 faces, and "v” is the speed of translation of the boxes along the path of movement 3. Successive orders to apply the label will follow according to the same time constant, as long as the second detection means 60 cannot detect a rear face.
  • the first label will be deposited on the first box from the emission of the signal delivered by the first means 52, the second label will be deposited after a time equal to that defined above from this first signal if no rear face detection has been carried out by the detection means 60, and this as many times as these means will not detect a rear face.
  • the second detection means 60 will detect the presence of a rear face by delivering a signal which will be interpreted as the end of the succession of boxes on contact, and therefore stop applying labels.
  • the operations described above can be resumed on arrival of the first box shifted from a previous one on the travel path, in the same way as explained above.
  • the means for affixing the labels described above are perfectly suited to the affixing of labels on all the boxes, with the essential aims: the simplification of the means feeding boxes and faster operation.
  • the device comprises means 70 for detecting the presence or absence of labels on the support strip 20, and in addition to being able to perfectly position the labels to be glued, relative to the end 26 of the corner 25, so that they are perfectly ready to be deposited.
  • these means 70 for detecting the presence of labels on the support strip 20 consist of two detectors 71, 72 associated with the strip for simultaneously detecting and respectively at a point each, the presence and the location of a perfectly defined point of a label, for example the rear edge 49 of a label, as illustrated in FIGS. 1 and 2.
  • These two points are separated by a distance equal to a multiple of the distance separating two identical parts of two consecutive labels, in fact the step of laying the labels on the support strip, for example the distance separating their two rear edges 49.
  • the the number of steps between these two detectors is chosen to be at least one unit greater than the maximum number of consecutive missing labels, a number that can be determined experimentally without difficulty. In the exemplary embodiment illustrated in FIGS. 1 and 2, these two points are three steps apart from fitting the labels to the support strip.
  • these two detectors are positioned to serve as a reference for positioning the label ready to be applied relative to the end 26 of the corner 25.
  • the position of the label ready to be applied is determined with respect to at least one point on a previous given label, for example the edge rear 49 of the fourth or seventh for the example illustrated.
  • each detector 71, 72 consists for example of an emitting source 74, for example of a light beam oriented towards the support strip so that its axis of propagation 75 is cut by the labels when the support strip takes place, and a photosensitive cell 76 disposed on the side of the support strip opposite to that where the source 74 is located, its photosensitive surface being placed on the optical axis 75 so as to be able to receive the light beam emitted by the source when, for example, there is no label or the beam is cut only by the support strip which is in this case chosen from a relatively transparent material.
  • the cells are capable of delivering to their outputs 77 a signal representative of the absence or presence of a label on the support strip 20. This signal also makes it possible to stop the running of the support strip when a label is found. ready to install.
  • the signals delivered by these two cells 76 are processed by the processing member 58.
  • the outputs 77 are connected to the inputs 78 of the processing member 58.
  • This processing member can possibly also play the role of source of power supply of the light emission sources 74, it includes outputs 79 capable of delivering this energy and connected to the power supply inputs 80 of the two sources 74.
  • the means 70 for detecting the presence of the labels and their positioning for example with respect to the end 26 of the corner 25 operate in the following manner:
  • the support strip 20 is initially unwound so as to be brought to an original position by passing in front of the two label detectors 71, 72. It is assumed that at the time of starting the strip, no label is missing from the start of that -this.
  • each detector more particularly each cell 76, delivers at its output 77 a signal indicating the presence of a label on the strip and also allowing the stopping of the strip so that a label is able to be applied. on a box in good position.
  • the positioning control signal will be given by the second detector 72. This result is obtained by the fact that the distance separating the two detectors has been chosen so that there is always a label detectable by one or the other of the two detectors.
  • the means 70 for detecting the presence or absence of labels on the support strip essentially constituted by these two detectors 71 and 72 also make it possible to locate the missing labels on the strip and therefore not to cause the end 26 of the corner 25 that a portion of strip having a label ready to be deposited, and not an empty strip space, which would result in either depositing several labels on the same box, or else obtaining at the exit of the device from unlabelled boxes.
  • the detector 72 detects the first empty label location, it suffices to count the number of labels capable of being deposited from this moment on to know that at the moment of placing this date label, it will be missing on the support strip, and it will therefore be necessary to advance the strip by controlling the drive motor 32 with a step of placing labels on the support strip to thereby eliminate the location not provided with 'label.
  • the two detectors 71, 72 can be moved longitudinally along the strip portion 35.
  • the means allowing this movement have not been shown for the sake of simplification of the drawing, all the more so since they do not present no difficulty of realization. They are for example of the same type as those described and illustrated for the two detectors 52 and 60.
  • the device comprises means for detecting the placement of labels.
  • These pose detection means consist for example of a third detector 90, for example of the same type as the detectors 71 and 72, associated with the end 26 of the corner 25, that is to say as close as possible from the place where the labels are applied, at level 5 on the boxes 1, 2, etc.
  • the strip may include an opening 73 at each location provided for a label and normally covered by a label.
  • the light beam going from the source to the cell can pass and allows the delivery of a signal which can be interpreted as a lack of label at the time of laying on a box.
  • This signal acts on the control of the stepping motor 32, via the processing member 58, to advance the strip until the presence of a label ready to be applied, and / or on an alarm.
  • the inputs and outputs 91 of the detector 90 are then connected to the inputs 92 of the logic processing member 58.
  • This logical processing unit does not, for its part, present any difficulty of implementation by an electronics engineer knowing the means of the invention described here and the exploitation of their operation. It is made up of logic gates, comparators, etc., and a microprocessor programmed for this purpose. These means are well known in themselves and will not be described more fully here.
