Definitions

  • the present invention relates to a box-making machine that incorporates a mechanism in charge of sucking the cardboard sheets from a reception area, where they are stacked to place them on a conveyor line to be taken to the shaping area where they are made into boxes.
  • the mechanism is configured to reduce the amount of space needed to a minimum and enable the machine to optimise the manufacturing speed of the boxes based on the size thereof.
  • it is activated by a geared motor, which is located next to the geared motor in charge of activating the male shaper, such that the mechanism can place the sheets on the conveyor line at the same level as the shaping area.
  • the invention is especially applicable to the industry of mechanisms for the manufacturing of folded cardboard boxes.
  • Document ES-2660059_B1 represents a box-making machine formed mainly by a reception area that incorporates a stacking area wherein the folded boxes are placed in the form of sheets and in which the boxes are collected, and a shaping area, defined by a pressing station that is delimited by longitudinal rails for guiding the box to be shaped, wherein the box is given its definitive shape.
  • a shaping device is in charge of moving the box from the reception area to the shaping area, and by means of a conveyor device, it collects a box by moving a pick-up arm that incorporates a system of suction cups in the direction of the reception area, along a front axis, to then moves in the direction of the shaping area, along a transverse axis, and delivers the box to the pressing station, where the box will then be finally shaped.
  • the shaping device incorporates a curved bar that causes the box to unfold in its turning movement along to the front axis, the box being sucked by the suction cup system but in an open-box position.
  • the box-making machine also incorporates two transverse folders, in charge of folding the transverse flaps of the base of the box and a pair of longitudinal folders, both separated the same distance from the width of the box to be shaped and configured in the form of inclined sheets that interfere with the longitudinal flaps of the box to fold them as the box advances.
  • the shaping device positions the box, held by the suction cup system and with the four bottom flaps already folded, in the shaping area to finish shaping the box into its definitive shape.
  • this invention has a drawback in that it includes too many mechanisms for moving the box from the reception area to the shaping area, requiring large dimensions for the machine.
  • Document ES-1127280_U describes a box-making machine that incorporates a cardboard sheet collection mechanism to take the sheets from the supply area to the conveyor line.
  • the mechanism is formed by two arms with suction cups joined by a shaft that is activated by a geared motor to be able to collapse and move from a vertical position in which the sheets are collected, to horizontal position in which they are placed on a conveyor line.
  • the mechanism is located in the lower area of the machine, placed within the conveyor line, such that it does not occupy additional space.
  • the present invention describes a box-making machine that incorporates a sheet supply mechanism that solves the previously mentioned problems.
  • a pick-up arm which comprises a system of suction cups with the ability to rotate to suck the boxes, such that the sheets are collected in a vertical position in accordance with how they are located in the stacking area of the reception area, to be placed on a conveyor line, by which they are taken to the shaping area, thereby reducing the dimensions of the machine without affecting the functionality thereof.
  • the mechanism is actuated by a geared motor located at the same level as the geared motor that activates the male shaper, in the upper area, so that it does not interfere with other elements of the machine.
  • the present invention describes a mechanism for supplying cardboard sheets of a box-making machine that is activated by a geared motor located on a fixed base, in addition to a cardboard sheet stacking area, a shaping area and a conveyor line intended to convey the collected sheets to the shaping area.
  • the mechanism comprises a plurality of suction cups connected to a pneumatic system configured to create a depression when activated and thereby be able to suck the sheets.
  • the mechanism is located in the proximity of the shaping area with the aim of having the lower edge of the sheets, according to the placement thereof in the stacking area, always next to the end of the conveyor line, where the glue guns are located, just before heading to the shaping area, being free at the other end to receive cardboard sheets with greater dimensions. This way, the cycle time is reduced to the minimum, thereby increasing the productivity of the machine.
  • the mechanism is configured by means of a pick-up arm formed by a first segment and a second segment joined in an articulated fashion by one of the ends thereof.
  • the first segment is solidly joined at the other end to the shaft of the geared motor.
  • the second segment is solidly joined at the other end to a support element to which a plurality of suction cups is fastened.
  • the second segment is joined, with sliding ability, to a fastening element which, in turn, is joined to the fixed base by a shaft with the ability to freely rotate.
  • movement of the geared motor causes a rotation of the first segment, which causes both the rotation as well as the sliding of the second segment with respect to the fixed base.
  • the geared motor has rotational movement to make the second segment rotate at the same time that it initially slides with respect to the fastening element to withdraw from the conveyor line and, continuing to rotate, slide in the opposite direction to move towards the stacking area and collect a cardboard sheet by suction.
  • the geared motor changes the direction of the rotation so that the second segment does the opposite movement, sliding with respect to the fastening element to withdraw from the stacking area, with the sheet collected, and then slide in the opposite direction to place it on the conveyor line, where the cycle ends.
  • the positions of the mechanism where the geared motor changes the direction of rotation are determined by detectors.
  • the support element of the mechanism can be a support shaft in which a pair of longitudinal members on each one of the ends, to which the plurality of suction cups is fastened.
  • the location of the suction cups on the longitudinal members as well as the longitudinal members on the support shaft is adjustable, such that the dimension of the cardboard sheets is not a limitation for the mechanism of the invention.
  • the present invention relates to a mechanism for supplying cardboard sheets (4) that is incorporated in a box-making machine by means of which the cardboard sheets (4) are collected in a stacking area (1) to be placed on a conveyor line (2) that takes them to the shaping area (3).
  • Figure 1 represents a side view of the mechanism of the invention located in the box-making machine.
  • the space between the stacking area (1) and the shaping area (3) is reduced to the minimum to provide a conveyor line (2) with a linear dimension that can be as small as the dimension of the cardboard sheets of the box to be shaped.
  • the machine is dimensioned to be able to receive cardboard sheets (4) with a specific maximum size.
  • the bottom side of the sheet (4) according to how it is placed in the stacking area (1), is always positioned in the gluing area, located at the entrance of the shaping area (3), the free space being in proximity to the stacking area (1).
  • the production speed is always the same, regardless of the size of the cardboard sheet (4), and the path of the conveyor belt (2) is optimised with respect to the length of the cardboard sheet (4).
  • Figure 2a represents the phase of collecting the cardboard sheet (4) from the stacking area (1) by the pick-up arm (6) of the mechanism.
  • Figure 2c represents the phase of placing the cardboard sheet (4) on the conveyor line (2).
  • Figure 3 represents the mechanism of the invention in an isolated fashion to show the components thereof in greater detail.
  • the mechanism is located on a fixed base (5) that supports the geared motor.
  • the mechanism is located in proximity to the shaping area (3), such that the sheets (4) can always be placed in proximity to the same, leaving a free space for production using sheets (4) of greater dimensions in proximity to the stacking area (1).
  • the mechanism is configured by a pick-up arm (6) that comprises a first segment (7) and a second segment (8) joined in an articulated fashion by one of the ends thereof.
  • the first segment (7) is solidly joined by the free end to the shaft of the geared motor.
  • the second segment (8) is joined by an intermediate area to a C-shaped fastening element (9), having the ability to slide on the same.
  • the fastening element (9) is joined to the fixed base (5) by means of a shaft with the ability to rotate freely.
  • a support shaft (10) is solidly joined to the free end of the second segment (8) by a central area, making up arms, to each one of which a longitudinal member (11) is fastened. At least one suction cup (12) is fastened to each one of the longitudinal members (11).
  • the position of the suction cups (12) on the longitudinal members (11) and the longitudinal member (11) on the support shaft (10) can be adjusted according to the user's specific needs, as well as the number of suction cups (12) and the dimensions of both the longitudinal members (11) and the support shaft (10), such that there is no limitation when collecting a cardboard sheet (4) due to the size thereof, the only limitation being the size of the machine.
  • the first detector (13) detects that the second segment (8) has reached its limit position and causes the geared motor to change the direction of rotation so that the second segment (8) carries out the opposite movement, sliding with respect to the fastening element (9) to remove itself from the stacking area (1), with the collected sheet (4), and then sliding in the opposite direction to place it on the conveyor line (2), where the second detector (14) detects the position of the second segment (8) and causes a change in the direction of rotation of the geared motor to begin a new cycle.
