Definitions

  • the subject of the present invention is a calibration method in a plate element processing machine, as well as a plate element processing machine implementing said method.
  • Such machines are used in particular in the printing and packaging industry, for example for making cardboard boxes from plate elements such as pre-printed cardboard sheets.
  • these sheets are removed from a stack located upstream of the machine, and are then positioned by an introducer in gripper bars mounted at regular intervals on a subsequent endless chain train.
  • the latter makes it possible to transport the sheets in the various subsequent processing stations of the machine.
  • such stations are dedicated to the cutting of leaves, the ejection of cutting waste and the receipt in stack of these sheets.
  • the train of chains moves and stops periodically so that during each move, all the gripper bars engaged with a sheet are moved from one station to the adjacent downstream station. If one wishes to obtain a printing or a shaping of quality, the positioning of the sheets within the different successive stations is a primordial operation.
  • the positioning of the sheet in the cutting station must be precise. Indeed, it should be ensured that the tools used for cutting, for example the form of cutting a platen press, are in perfect register with the impression that has been made beforehand on the sheet.
  • the patent CH 690'470 describes a device for ensuring the quality of the production of a packaging manufacturing press.
  • this device comprises a camera for reading, on the one hand registration marks related to printing, and on the other hand a mark for locating the position of the cutting. These registration marks are arranged on the front waste of the sheet held by the clip bar.
  • the cutting mark is made by means of a perforator integral with the cutting tools. This perforator provides a hole in the front waste of the sheet simultaneously with the cutting of the latter.
  • another device makes it possible to mark the sheets identified as defective by the camera, namely those which have an off-tolerance offset between printing and cutting.
  • the patent EP 1'044'908 relates to a device and method for positioning plate elements in an introduction station. Starting from a tablet located in a starting rear position, this method consists in switching on means for fixing a plate element on the tablet, and then controlling actuators to enable its forward displacement as a function of the position of the plate element on the tablet. As a result, the front edge of the plate member is brought, stopped and released into a predetermined position in the clamps of the gripper bar of the transport device before the shelf has finally been returned to the starting position.
  • optoelectronic means read the coordinates of the position of the plate element and calculate the displacement necessary to position it at best in the clip bar.
  • the object of the present invention is to overcome the aforementioned drawbacks so as to reduce the start-up time of new work, the consumption of plate elements during this start-up, and to improve the quality obtained.
  • the subject of the present invention is a calibration method in a processing machine, as claimed in claim 1, and a plate element processing machine implementing this method in accordance with the present invention. states claim 5
  • upstream and downstream will be defined with reference to the direction of movement of the plate elements, as illustrated by the arrow D in FIG. figure 2 . These elements move from upstream to downstream, generally following the main axis X of the machine, in a movement clocked by periodic stops. Also, it will be specified that the adjectives longitudinal and lateral are defined with respect to this main axis X.
  • plate elements and sheets will be considered as equivalent, and will concern both elements made of corrugated cardboard that of cardboard or any other material commonly used in the packaging industry.
  • the figure 1 shows a schematic overview of a processing machine 1 in which the method of the present invention can be applied.

Thanks to the gap left at the bottom of the gauge 6, these elements can be removed one by one from the bottom of a stack 11 by means of an introducer 20.
  • This device will allow to introduce each of them in an organ for gripping 31 of a conveyor 30, as best seen in the figure 2 .
  • This transporter generally consists of a chain train 32, between the chains of which are arranged a a plurality of gripper bars each acting as a gripping member 30 for the plate member 10.
  • the chain train 32 moves and stops periodically so that during a movement, each gripper 31 has moved from one station to the adjacent downstream station.
  • the position of the stops of the gripping members is dictated by a movement of the chain train a constant distance. This distance corresponds to the theoretical pitch of these organs on the train of chains.
  • Treatment stations 2, 3, 4 and 5 are fixed and spaced apart by this same step so that at each stop, the gripping members 31 stop in tracking with the tools of these stations.

  • the sensors 7 integrate the lighting devices.

Knowing the theoretical stopping position of the gripping member 31 in the insertion station, the control unit is capable of calculating the values of the displacement parameters (lateral, longitudinal or transverse) of the introducer 20, so that the latter correctly conveys the plate element which it carries in the gripping member, according to its initial starting position. These calculations are performed by the control unit 40 which also controls the introducer 20.
  • the plate member 10 will then be transported by the gripping member 31 in the cutting station 3, where it will be cut into a die corresponding to the desired shape, for example in order to obtain a plurality of boxes of a given form.
  • this station or in one or more subsequent stations, can also be performed other operations such as creasing fold lines, embossing some surfaces and / or the removal of patterns from metallized strips for example.

As described in this document, positioning occurs at the end of the margin table closest to the transport members 5 of the cutting station, using a sophisticated system that does not require the leaves to stop.

  • sensors measure the reflected light intensity, which makes it possible to calculate the position of the registration marks and the movement that the tablet of the positioning device must make in order to correctly place the downstream edge of the plate element in the organ.
