Definitions

  • the invention relates to a folding box erecting device in a cartoning machine, with a storage shaft in which a folding box stack is arranged, a counter-suction device, a depositing location and a transport device by means of which at least one suction device can be moved between the folding box stack, the counter-suction device and the depositing location.
  • a cartoning machine places products or product stacks into a folding box, which is then sealed.
  • a cartoning machine of typical design has a folding box conveyor with a plurality of receiving positions arranged one behind the other, each for a single folding box, and a product conveyor with a plurality of receiving positions arranged one behind the other, each for a product or product group.
  • the folding box conveyor and the product conveyor run alongside each other, at least in sections, and in a transfer unit, the products are usually pushed laterally into the adjacent open folding box.
  • a folding carton erecting device is arranged upstream of the transfer unit.
  • the folding boxes are fed into a storage chute in a folded, flat state in the form of a stack of folding boxes.
  • the bottom folding box of the stack of folding boxes can be grasped by a suction cup and pulled out of the storage chute and removed.
  • the suction cup holds the still flat folding box and moves it against a counter suction cup, which sucks and holds the folding box on another side.
  • the folding box By moving the suction cup relative to the counter suction cup, the folding box can be pulled apart and thus erected. If necessary, the folding box is moved against stops to achieve the desired erected shape and then placed either directly on the folding carton conveyor or in an intermediate storage location.
  • the vacuum cleaner travels along a relatively complex, closed curved path, a so-called cycloid, which is achieved by superimposing several movements, usually defined by control curves.
  • These movements defined by control curves have the disadvantage that, on the one hand, they are very complex to construct and, on the other hand, they follow a fixed sequence, so that changing the curve requires considerable design effort.
  • the 1st axis (X-axis) and the 2nd axis (Y-axis) preferably run perpendicular to one another, so that by appropriately controlling the drive devices, many points in the plane spanned by the 1st axis (X-axis) and the 2nd axis (Y-axis) can be approached.
  • the 1st axis (X-axis), the 2nd axis (Y-axis) and the 3rd axis (Z-axis) are each perpendicular to each other.
  • the first axis (X-axis) runs in the direction of removal of a folding box from the storage chute.
  • the bottom folding box of the folding box stack is removed in the stacking direction, so that the first axis (X-axis) preferably runs in the stacking direction or in the longitudinal direction of the folding box stack.
  • the second axis (Y-axis) runs perpendicular to a suction and contact surface of the counter-suction device.
  • the counter-suction device comes into contact with the folding box surface at its suction and contact surface and holds it there due to a generated negative pressure.
  • the transport device is aligned so that the second axis (Y-axis) runs perpendicular to the suction and contact surface of the counter-suction device and, when the folding box is suctioned onto it, also perpendicular to the suctioned surface of the folding box.
  • suction cups pointing in opposite directions are arranged on the holder.
  • the suction and contact surfaces of the suction cups, which point in opposite directions, are thus offset by 180° in the circumferential direction.
  • a monitoring device can be provided by means of which the shape of the partially or fully erected folding box can be detected.
  • the monitoring device can comprise a camera and/or sensors which determine whether the folding box has a predetermined target shape before being deposited on the depositing station.
  • the shape of the erected folding box can be detected by means of the monitoring device. If it is determined that the desired target shape has not been achieved, the An incorrectly erected folding box is not placed on the storage location but is either ejected or an attempt is made to erect the folding box correctly the next time it passes the counter-suction device.
  • the folding box is transferred to the storage location.
  • the holder is continuously rotated around the third axis (Z-axis) at a constant or varying speed.
  • the holder is rotated stepwise around the third axis (Z-axis), with rotation in particular in steps of 45° or 60°, so that each suction cup returns to its starting position after eight or six steps, respectively.
  • the main shaft is then rotated by 45° so that the folding box which has just been pulled off and is still lying flat is in an intermediate position between the storage shaft and the counter suction cup, while the folding box which has already been erected on the opposite suction cup is deposited on the depositing position 29.
  • the main shaft is then rotated another 45° so that the folding carton, still lying flat and gripped by the first suction cup, lies parallel to the suction and contact surface of the counter suction cup.
  • the support carriage, together with the holder and the suction cups, is then moved along the second Y-axis toward the counter suction cup until the surface of the folding carton facing away from the suction cup rests against the suction and contact surface of the counter suction cup.
  • the support carriage is then moved back along the 2nd axis Y, whereby the counter suction cup still holds the folding box on its outside, whereby the folding box is aligned
  • the erecting finger is rotated by 90° via a gear, thus supporting the erecting movement of the folding box.
  • the main shaft is rotated again and at the same time the carriage is moved in the direction of the folding box stack along the 1st axis X, so that a state is reached again which corresponds to the initial state with the difference that the other suction cup is now in contact with the folding box stack.
  • a counter-suction device 30 is arranged offset by 90° to the storage shaft 11 and has a suction and contact surface 30.1 facing the interior of the base frame 24. Furthermore, a storage location 29 is formed on the base frame 24, onto which the folding box FS can be placed after it has been erected.
  • a support carriage 21 is mounted on a cross member 20 of the carriage 19, which can be moved bidirectionally, i.e., back and forth, along a second linear guide 23 formed by the cross member 20 of the carriage 19 by means of a drive device (not shown) along a second axis Y, as indicated by the double arrow B.
  • the second axis Y runs perpendicular to the first axis X.
  • a main shaft 26 which runs in the direction of a 3rd axis Z, whereby the 3rd axis Z is perpendicular to the 1st axis X as well as perpendicular to the 2nd axis Y and perpendicular to the plane of the drawing in Fig. 1
  • the main shaft 26 is rotationally driven and can be rotated about the 3rd axis Z, as indicated by arrow D.
  • a holder 16 is mounted on the main shaft 26 and rotates together with the main shaft 26.
  • Two suction cups 15, 25 are provided on the holder 16, with their suction and contact surfaces 15.1, 25.1 facing in opposite directions.
  • the suction cups 15, 25 are each connected to the holder 16 via a suction cup holder 22, with the suction cup holders 22 each additionally pivotably supporting a raising finger 27.
  • the main shaft 26 can be rotated in steps of, for example, 45° each until it reaches its starting position again.
  • the suction cup 15 rests with its suction and contact surface 15.1 on the underside of the lower folding box FS of the folding box stack 12.
  • the other suction cup 25 carries a previously erected folding box FS' on its suction and contact surface 25.1, which is additionally supported by the erecting finger 27 and is located in an intermediate position between the counter suction cup 30 and the storage location 29.
  • the carriage 19 together with its superstructures is moved in the direction of the 1st axis X away from the folding box stack 12, whereby the lower folding box FS of the folding box stack 12 is pulled out of the storage shaft 11.
  • the erecting finger 27 lies in a plane with the suction and contact surface 15.1 of the suction device 15 and supports the folding box FS which is still lying flat.
  • the main shaft 26 is then rotated by 45°, so that the folding box FS which has just been pulled off and is still lying flat is in an intermediate position between the storage shaft 11 and the counter suction cups 30, while the folding box FS which has already been erected on the opposite suction cup 25 is deposited on the depositing position 29.
  • the position is in Fig. 2 shown.
  • the main shaft 26 is then rotated again by 45° so that the folding box FS, still lying flat and gripped by the first suction cup 15.1, lies parallel to the suction and contact surface 30.1 of the counter suction cup 30.
  • the support carriage 21 is then moved together with the holder 16 and the suction cups 15, 25 along the second axis Y in the direction of the counter suction cup 30 until the surface of the folding box FS facing away from the suction cup 15 rests against the suction and contact surface 30.1 of the counter suction cup 30. This state is shown in Fig. 3 shown.
  • the support carriage 21 is then retracted along the second axis Y, with the counter suction cup 30 still holding the folding box FS on its outer side, thereby aligning the folding box FS.
  • the erecting finger 27 is rotated by 90° via a gear mechanism (not shown), thus supporting the erecting movement of the folding box FS.
  • the main shaft 26 is rotated again and at the same time the Carriage 19 is moved in the direction of the folding box stack 12 along the 1st axis X, so that a state is now reached again which corresponds to the state according to Fig. 1 with the difference that the suction cup 25 now rests against the stack of folding boxes 12.
  • a monitoring device 28 is provided, only schematically indicated.
  • This monitoring device may have a camera and/or sensors to check whether the folding box FS, which is about to be deposited at the depositing location, is properly erected. If this is not the case, the incorrectly erected folding box FS is not deposited at the depositing location 29, but is either ejected or another attempt is made to erect the folding box FS using the folding box erection device 10.
