Definitions

  • the present invention relates to a machine for wrapping already formed boxes, in particular cardboard boxes, with a covering sheet, in particular a sheet of paper or similar material.
  • the upper gripping unit is arranged to grip the assembly formed by the box and the covering sheet coming from the feeding station and to move it both vertically and horizontally (more precisely, along a direction parallel to the longitudinal direction, or direction of travel, of the belt of the feeding station).
  • the lower abutting unit is vertically movable and is provided with elastic means tending to urge it upwards, so as to exert an abutting action onto the bottom wall of the box, on a side opposite to that of the upper gripping unit, and thus ensure that the box is retained between the upper gripping unit and the lower abutting unit.
  • the lower working unit includes a plurality of working devices arranged to work on the assembly formed by the box and the covering sheet carried by the upper gripping unit to cause a respective edge of the covering sheet to adhere to the outer face of each side wall of the box, as well as to fold the edge of the covering sheet onto the inner face of the side wall.
  • the lower working unit is stationary, i.e. integral with the structure of the machine.
  • the assembly formed by the box and the covering sheet is then moved by the upper gripping unit, that - as already stated above - acts in opposition with the lower abutting unit, relative to the lower working unit.
  • a semi-automatic machine i.e. a machine in which the box is placed on the covering sheet manually by an operator, instead of automatically by a robot, an increase in the vertical position of the belt clearly results in an increase in the vertical position of the working plane of the operator, which may lead to the need to use tools (for example platforms) to ensure ergonomically correct working conditions for the operator.
  • a further shortcoming of the known machines is that, in the case where the machines must process high boxes (i.e. boxes with a height equal, for example, to 240 mm), the upper gripping unit is required to make long travels, which involves an increase in the travel times and hence a reduction in the productivity of the machine.
  • the present invention aims at providing a machine which is able to process high boxes (i.e. boxes with a height equal, for example, to 240 mm) and, at the same time, has a lower height from the ground of the belt of the conveyor unit than the prior art and has an overall height lower than the maximum internal height (2.360 mm) of a conventional ISO container, so that it can be transported in a container without having to be disassembled into several parts.
  • the first and second vertical driving means are configured to control the vertical movements of the upper gripping unit and of the lower working unit, respectively, in a synchronous and phased manner.
  • the two units are preferably moved simultaneously and at the same speed, but of course in opposite directions, by the respective vertical driving means.
  • each relative displacement of the upper gripping unit with respect to the lower working unit results in absolute displacements of the same amount (equal to half the amount of the relative displacement), but in opposite directions, of the two units.
  • the feeding station 12 basically comprises a feeding unit 16, a glue spreading unit 18 and a conveyor unit 20.
  • the upper gripping unit 38 comprises a gripping device 44 slidably mounted on a beam 46 oriented with its own longitudinal axis along the aforementioned horizontal axis x.
  • the gripping device 44 is carried by a carriage 48 which is slidable on guides 50 (in particular a pair of guides) mounted on the beam 46 and oriented along the horizontal axis x.
  • the pinions 64 mounted on the brackets 60 are drivingly connected for rotation with each other by means of a transmission shaft 68 and are driven into rotation by means of a single motor 69, in particular an electric motor.
  • the gripping device 44 comprises a body 70, which in the present example is attached to the carriage 48 so as to be drivingly connected with the latter for translation on the beam 46 along the horizontal axis x.
  • the gripping device 44 further comprises a head 72 placed below the body 70 and comprising in turn a first head portion 74, which is stationary with respect to the body 70 (and for this reason will be hereinafter referred to, for ease of understanding, as “stationary head portion”), and a second head portion 76, which is - on the other hand - vertically movable with respect to the body 70 (and for this reason will be hereinafter referred to, for ease of understanding, as “movable head portion”), and hence with respect to the stationary head portion 74.
  • stationary head portion which is stationary with respect to the body 70
  • second head portion 76 which is - on the other hand - vertically movable with respect to the body 70 (and for this reason will be hereinafter referred to, for ease of understanding, as “movable head portion”
  • the stationary head portion 74 is mounted at the bottom end of a first vertical rod 78, which is fixed to the body 70, whereas the movable head portion 76 is mounted at the bottom end of a second vertical rod 80, which is vertically movable with respect to the body 70 under control of a linear actuator 82, for example a pneumatic cylinder or an electric motor associated to a motion conversion mechanism.
  • a linear actuator 82 for example a pneumatic cylinder or an electric motor associated to a motion conversion mechanism.
  • the support plate 92 along with the first and second working devices 88 and 90, is mounted on the structure 28 of the working station 14 so as to be vertically movable.
  • respective blocks 96 are mounted, each of which carries at least one pad 98 (two pads, in the illustrated example) slidably mounted on a respective linear guide 100 (which can be seen in Figures 3 and 4 ) oriented vertically and fixed to the structure 28.
  • two pairs of linear guides 100 are mounted on a side of the structure 28 extending parallel to the aforementioned axis x, while the other two pairs of linear guides 100 are mounted on the opposite and parallel side of the structure 28.
  • the driving system which controls the vertical movement of the lower working unit 42 and the driving system which controls the vertical movement of the upper gripping unit 38 are configured to control the vertical movements of these elements in a synchronous and phased manner, but in opposite directions.
  • a given relative movement of the two units 38 and 42 towards each other will be obtained for example by causing the beam 44 of the upper gripping unit 38 to move downwards with a certain speed and by simultaneously causing the support plate 92 of the lower working unit 42 to move upwards with the same speed.
  • Each first working device 88 further comprises a horizontal blade element 118, which extends parallel to the axis x close to the upper edge of the pressure plate 110, between the same pressure plate and the roller 114, and a linear actuation device 120, for example a pneumatic cylinder, operatively associated to the horizontal blade element 118 to move it in either direction along the axis y.
  • a linear actuation device 120 for example a pneumatic cylinder
  • the movable head portion 76 of the head 72 of the gripping device 44 is moved upwards under control of the linear actuator 82 until it completely disengages from the box B, while the stationary head portion 74 remains in the same position to keep the box B stationary with respect to the two first working devices 88.
  • the movable head portion 76 of the head 72 of the gripping device 44 is moved downwards under control of the linear actuator 82 and thus contributes to further fold the upper edges of the portions S 1 and S 2 of the covering sheet S pressing them against the inner faces of the respective side walls SW 1 and SW 2 of the box B.
  • the upper edges of the portions S 1 and S 2 of the covering sheet S are at this time folded back onto the inner faces of the respective side walls SW 1 and SW 2 of the box B by means of the horizontal blade elements 118.
  • the pressure plates 110 are urged by the respective linear actuation devices 112 to press each the respective portion S 1 , S 2 of the covering sheet S against the respective side wall SW 1 , SW 2 of the box B so as to ensure a perfect adhesion of the covering sheet onto these walls.
  • the vertical blade elements 122 have the function of folding the tabs T 1 and T 2 of the portions S 1 and S 2 of the covering sheet S to cause them to adhere to the outer faces of the side walls SW 3 and SW 4 of the box B, as explained above regarding step d) of the box wrapping process with reference to Figure 2 .
  • each second working device 90 comprises a support structure 130, a pressure plate 132 lying in a vertical plane parallel to the aforementioned axis y and a linear actuation device 134, for example a pneumatic cylinder, operatively associated to the pressure plate 132 to move it in either direction along the axis x (that is to say, perpendicular to the axis y).
  • a linear actuation device 134 for example a pneumatic cylinder
  • Each second working device 90 further comprises a horizontal blade element 140, which extends parallel to the axis y close to the upper edge of the pressure plate 132, between the same pressure plate and the roller 136, and a linear actuation device 142, for example a pneumatic cylinder, operatively associated to the horizontal blade element 140 to move it in either direction along the axis x.
  • a linear actuation device 142 for example a pneumatic cylinder
  • the machine 10 further comprises a control unit (not shown) configured to automatically control, according to a predetermined working cycle, the movements of the various units of the feeding station 12 and of the working station 14 to supply each time the working station 14 with one box and covering sheet assembly and to carry out each time, on that assembly, the working steps required to wrap the box B with the covering sheet S.
  • a control unit (not shown) configured to automatically control, according to a predetermined working cycle, the movements of the various units of the feeding station 12 and of the working station 14 to supply each time the working station 14 with one box and covering sheet assembly and to carry out each time, on that assembly, the working steps required to wrap the box B with the covering sheet S.
  • the conveyor unit 20 of the feeding station 12 has a telescopic structure, in that a proximal end portion thereof (i.e.
  • the transport belt 26 extends to a larger amount into the working station 14, arriving underneath the gripping device 44 and hence allowing the latter to grip the box and covering sheet assembly substantially with no need of movement along the axis x, unless to ensure a perfect alignment of the head 72 with the box B.
  • rollers 22 and 24 of the glue spreading unit 18 of the feeding station 12 are provided with respective electrical resistances 146 and 148 inserted into them so as to generate heat when an electric current flows therethrough and thus heat the rollers to prevent the glue from solidifying while the latter is being spread onto the covering sheet S.
  • the need to use the complex and expensive water heating systems of the known machines is thereby avoided.
  • the aspect of the invention relating to the telescopic configuration of the conveyor unit of the feeding station may be provided for independently of the aspect of the invention relating to the vertically movable arrangement of the lower working unit.
