Definitions

  • the technical field relates to the treatment of flat objects, for example folding boxes in planar configuration, and which are arranged in overlap so as to optimize handling, including transport and storage in a container.
  • folding boxes In the packaging industry, the manufacture of folding boxes is usually done on a production line by folding and gluing cuts by means of machines commonly called folder-gluers. Generally, the folding boxes are arranged to form a continuous web at the exit of a folder-gluer. The boxes are then in a flat configuration, that is to say that the different panels of each box are folded to essentially eliminate all their internal volume and thus minimize the space occupied before their first use. Each box in planar configuration then has a length, a width and a thickness, which thickness is significantly smaller than the length and the width.
  • Folding boxes made in a factory are not necessarily used immediately and in the same place where they were made. It is therefore common to keep them in a flat configuration and put them in a container.
  • the container may be for example a corrugated cardboard box that can receive a multitude of flat objects in order to be able to transport and store them before their first use.
  • Other types of containers may also be used instead of a carton box.
  • the flat objects are folding boxes, they may include automatic bottom boxes, which have a natural tendency to slightly open when they rest individually on a flat surface. This facilitates handling by the equipment when using the boxes but will often complicate their packaging immediately after manufacture.
  • the folding boxes After being manufactured in a folder-gluer, the folding boxes are usually arranged overlapping on a conveyor.
  • This conveyor is generally in the form of a treadmill disposed horizontally and receiving the boxes on its upper surface in motion.
  • the overlapping of the boxes is achieved by partially overlapping them in the direction of travel of the conveyor.
  • the stream of overlapping boxes forms what is called a tablecloth.
  • a web generally has a multitude of overlapping boxes in planar configuration.
  • the web at the exit of the folder-gluer is called the initial web.
  • a web may be continuous or discontinuous.
  • a web is discontinuous when two successive boxes are spaced on a conveyor. In some cases, a discontinuous sheet could also include only one box.
  • a folding box in planar configuration or any other flat object of the same kind, is not of a uniform thickness on all its surface.
  • one of its edges may be thicker than one or more other edges.
  • This difference in thickness is cumulative during a stack and a package created by stacking a number of boxes (or other flat objects) will not be uniform in size when placed in the container.
  • packers The machines used for the containerization operation are hereinafter referred to as "packers".
  • packers There are different types of packers, for example semi-automatic packagers where each machine is assisted in the handling of boxes by an operator, and automatic packagers where the handling is done only by the packer, without human intervention.
  • Another challenge in the design of packaging equipment is to allow new configurations without necessarily excluding existing configurations or having to remake the entire equipment.
  • the same basic equipment could serve different needs.
  • the use of several existing equipment to train new is an approach that can save significant time and money because it avoids having to make the design completely new.
  • This approach also often favors the versatility of new equipment compared to those designed for a single configuration.
  • it is not the simplest because you have to combine, in the right way, the right equipment and the right technologies. Integrating two things can create many additional challenges.
  • the proposed concept relates to an automatic flat object processing system for packaging articles in a container, for example folding boxes in the conventional "glue tab up" configuration and / or in one or two new additional configurations, for example: “glue tab down” and “glue tab down with reverse boxes”.
  • the system can be designed on the basis of an automatic packer with forced angle transfer and vertical accumulation but with the particularity that it can still be designed to perform one or both additional packaging modes as needed customers of the equipment manufacturer, therefore to allow the packaging of boxes in additional configurations "glue tab down” and / or "glue tab down with reverse boxes”.
  • the system can make it possible to effectively package the folding boxes, especially those of the automatic bottom type, to allow one or two additional packaging modes to be added by using the base of an existing automatic transfer packer. to the forced angle and vertical accumulation, and / or allow the addition of these new functions in the form of an inverter device that can be integrated or not an existing packager with the minimum of modifications.
  • the proposed concept includes arranging an inverter device for can webs in the direction of arrival of the boxes to a packer and that the inverter device can be placed obliquely to also move the webs vertically.
  • the figure 1 is a schematic view of an example of a packaging system 100 according to the proposed concept.
  • This system 100 allows the packaging of folding boxes in three different modes of packaging.
  • This system 100 partly uses an existing packager but to which modifications have been made in order to improve its operation.
  • Reference numeral 102 generally designates the section of system 100 that corresponds to the packager.
  • figure 1 is simplified representations to understand the general operation.
  • the various figures comprise a geometric reference 200 with the coordinates XYZ.
  • the marker 200 makes it possible to compare the views between them.
  • Flat objects which are folding boxes 104 in planar configuration in this example, arrive in a sheet on an input conveyor 106, for example from a folder-gluer.
  • This Input conveyor 106 routes boxes 104 to system 100 and, depending on the mode, also routes boxes 104 to packer 102.
  • the second half of the input conveyor 106 could also be a second conveyor placed between the end of the input conveyor 106 and the packer 102. The two cases are equivalent.
  • the boxes 104 arriving from the input conveyor 106 pass through a counting device 120 which counts the number of boxes 104 on arrival at the system 100.
  • the counting device 120 could also be placed much further upstream of the system 100. boxes 104 placed on the input conveyor 106 then form a continuous web 110.
  • the continuous web 110 passes in a straight line through a switching device 122 and continues on a second conveyor 107 following a first path (T1).
  • the system 100 is configured for a conditioning mode hereinafter referred to as the "standard mode".
  • the standard mode corresponds to the usual mode of operation of a known packager and is the one where the boxes 104 will be oriented "glue tab upwards" in the container.
  • the boxes 104 of the sheet 110 illustrated in FIG. figure 1 arrive at the packer 102 in a transfer module 130.
  • This transfer module 130 is of the type to the left to the obligatory left.
  • the boxes 104 change direction and accumulate immediately after near vertical in an accumulation zone 132.
  • the boxes 104 in the accumulation zone 132 are counted and then separated by a counting device. separation 134 from which they are sent in an arch conveyor 135 in the form of discontinuous sheet 112, still following the first path (T1), to a container 140 placed at the exit of the packer 102.
  • Each discontinuous sheet 112 comprises a predetermined number of boxes 104 which will form a package to be placed in the container 140.
  • Each sheet 112 passes in particular a switching device 136 and then on a curved filling arm 138.
  • the filling arm 138 in this example allows the boxes 104 to fall into the open top container 140, which container is located on a filling station 146 (see FIGS. figures 5 and 6 ) which moves it in the filling direction indicated by the arrow 142 while the boxes 104 fall vertically.
  • the direction is only an example.
  • the container 140 can receive several packets before being considered as being filled, after which it will be replaced by an empty container in turn to be filled.
  • the container 140 in the example is a box of rectangular shaped cardboard and open upwards.
  • the box comprises flaps that allow to close the container 140.
  • Other forms of containers and / or types of containers and / or materials are also possible.
  • the figure 2 is a view similar to the figure 1 but in which the boxes 104 are placed in a container 140 according to another mode of conditioning called hereinafter the "glue leg mode down".
  • the boxes 104 will therefore be oriented differently from those which have been conveyed to the container 140 of the figure 1 . They follow a second path of boxes (T2).
  • the boxes 104 in the example illustrated in FIG. figure 2 arrive on the input conveyor 106 and are counted by the counting device 120. However, these boxes 104 exit the switching device 122 through another outlet to form a discontinuous sheet 114 which will be sent on a climbing conveyor 150. The boxes 104 of the web 114 will form a package.
  • the climbing conveyor 150 is diagonally upwardly and conveys the web 114 to the packer 102, more precisely to a transfer module 152.
  • the climbing conveyor 150 is part of an inverter device 108.
  • This is a piece of equipment based in part on existing equipment, such as that presented in Canadian patent no. 2584937 issued on 29 April 2014 and in its equivalent in the United States, namely 7360636 issued April 22, 2008. Variants are also possible.
  • the transfer module 152 at the figure 2 is of the type transfer to the square to the right obliged.
  • the boxes 104 of the web 114 change direction during their passage in the transfer module 152, then they are conveyed to the output of the packer 102 by a conveyor 154.
  • the transfer module 152 and the Conveyor 154 are items that were not in the original packager at the base of the one now used in system 100 shown as an example.
  • 104 boxes 104 of the web do not have to go through the transfer module 130, which can be very advantageous.
  • Boxes 104 following the second path (T2) shown in FIG. figure 2 pass through the switching device 136 which redirects the web 114 to the filling arm 138 from which the boxes 104 will fall into the container 140.
  • the container 140 moves in the filling direction indicated by the arrow 144 during its filling .
  • These boxes 104 are thus packaged in the container 140 with an orientation of 180 ° with respect to the boxes 104 which followed the first path (T1) illustrated in FIG. figure 1 .
  • the figure 3 is a view similar to the figure 2 but in which the boxes 104 follow a third path of boxes (T3). They will also have an orientation where the glue tab is down, like those of the figure 2 . However, while having the glue tab down, the direction of the boxes 104 following the third box path (T3) is reversed by 180 degrees in comparison with that of the boxes 104 which will have followed the second path (T2) shown. to the figure 2 .
  • the conditioning mode of the figure 3 is hereinafter called "glue tab down with inverted boxes”. Therefore, the boxes 104 that will have followed the third path (T3) shown at figure 3 will be doubly inverted compared to those that will have followed the first path (T1) shown at figure 1 .
  • the boxes 104 in the example illustrated in FIG. figure 3 arrive from the input conveyor 106 and are counted by the counting device 120. However, these boxes will exit the switching device 122 by a third output which will send them on a first section of conveyors 160.
  • the boxes 104 will form a discontinuous web 116.
  • This first section 160 is part of the inverter device 108 in this example and may include several conveyors.
  • the end of the first section 160 is located at a height that can receive all the boxes 104 of the web 116 before the web 116 can be redirected in another direction to the packer 102. This operation will allow to reverse the direction of the boxes 104 of the web 116.
  • the web 116 will exit through a second section 162 of conveyors. The last box 104 of the tablecloth 116 will then become the first one.
  • the inverted web 116 will be directed to the transfer module 152, namely the same as the one having received the boxes 104 of the second path (T2).
  • a packet could be formed by the boxes 104 of several small successive layers 116 to allow a reduction in the size of the inverter device 108.
