Definitions

  • the present invention relates to a device for stacking flat objects, in particular printed boxes folded flat, comprising means for bringing the boxes under a stack already formed in a stacking station comprising at least one front stop and a device squaring the boxes, means for supporting the front and rear of the already formed stack of boxes and means for supporting the front and rear of a new box to be stacked.
  • Devices of the kind to which the invention relates are generally used in machines for shaping corrugated cardboard in which they are placed at the end of the machine, just before a stringing station.
  • French Patent No. 2,087,732 provides a description of the components of such a stacking device.
  • the present invention aims to eliminate the aforementioned drawbacks.
  • the invention as characterized in the claims, solves the problem of creating a device for stacking flat objects authorizing the feeding under a stack already formed of a printed and folded box, while reducing to the extreme the friction distance between the lower box of the already formed stack and the box being received under the stack.
  • FIG. 1 schematically represent the operating cycle of the stacking device.
  • the stacking device shown in FIG. 1 comprises a lower conveyor 1 constituted by a series of endless belts 2 placed side by side and an upper conveyor 3, also constituted by endless belts 4 placed one next to the other.
  • the belts 2 of the lower conveyor 1 are supported, in the stacking zone, by drive pulleys 5, as well as by a lifting member 6 pivotally mounted on the shaft 8 of the return pulleys 9.
  • the boxes 15 are brought to the belts 2 of the lower conveyor 1 by a second lower conveyor 62 formed of belts 63 placed side by side between the belts 2.
  • the belts 63 are supported by drive pulleys 64 mounted on the same shaft 65 as the drive pulleys 5 of the lower conveyor 1 (see figure 10).
  • the stacking device also comprises a support member 10 from the front of the stack of boxes 11, a support member 12 from the rear of the stack of boxes 11 and a support member 13 from the rear of the box 15.
  • the support member 10 of the front of the stack of boxes 11 is constituted by a comb 17 (see FIGS. 6, 8 and 9) moving in the direction indicated by the arrow 14, this in synchronism with the 'advance of the box 15 arriving in the direction indicated by the arrow 16 in the stacking area.
  • the movement of the comb 17 is also synchronized with the movement of the lifting member 6, the movement of the support member 13 from the back of the boxes and the movement of the support member 12 from the rear of the stack of boxes 11.
  • the support member 13 from the back of the box 15 is constituted by a series of sectors 61 placed side by side along a transverse shaft 60 (see Figure 10).
  • the stacking station has a front stop 18 and a squaring device 19 for the stack of boxes 11.
  • the front stop is stationary, but adjustable, depending on the format of the boxes to be stacked, while the squaring device 19 is driven in a continuous back-and-forth movement in the direction indicated by the double arrow 20.
  • the phase shown in Figure 1 corresponds to the arrival of a new box 15 to be stacked under the stack of boxes 11 already formed.
  • the new box 15 leaving the lower 1 and upper 3 conveyors is frictionally driven by the single lower conveyor 1 and the comb 17 begins to move in the direction of the arrow 14.
  • the support members 12 and 13 of the rear of the battery 11 and of the box 15 are also moving in the direction indicated by the arrows 21 and 22 and the lifting member 6 begins to move in the direction indicated by the arrow 23.
  • the setting in motion of all the organs mentioned above can be controlled for example by a means of detecting the arrival of the new box 15 in the stacking area.
  • This detection means could for example be constituted by a photoelectric cell detecting the front of the new box 15 and transmitting this information to the control devices of the various organs mentioned above. At this stage of operation, no friction occurs between the box 15 and the belts 2.
  • the stacking device is shown in Figure 2, in the phase corresponding to the start of the establishment of the new box 15 under the stack 11.
  • the front of the new box 15 is brought against the support member 10 from the front of the stack 11 by belts 2.
  • the support member 10 from the front of the stack will be moved so that it passes from position 10 'to position 10 ".
  • the support member 13 of the rear of the box 15 will come against it by passing from position 13' at position 13 "and the lifting member 6 at the front of the box will have been moved from position 6 'to position 6".
  • the support member 12 at the rear of the stack of boxes 11 will have , meanwhile, turned in the direction indicated by the arrow 21.
  • FIG. 3 represents the terminal phase of placing the new box 15 under the stack 11.
  • the lifting member 6 of the front of the box occupies its highest position, represented by 6 "'.
  • the support member 10 at the front of the stack of boxes will be at the end of its travel, in its position 10"' and the support member 13 at the back of the box will continue to rotate in the direction indicated by arrow 22.
  • the support member 12 from the rear of the stack 11, still rotating in the direction indicated by arrow 21, will have its notch 24 opposite the rear edge of the box 15, so that it can be placed under the stack 11 without its rear edge being damaged by said support member 12.
  • FIG. 4 shows the position of the various elements at the end of the cycle for setting up the box 15 under the stack 11.
  • the support member 10 at the front of the stack begins to move in the direction of the arrow 25 and therefore supports the front part of the stack, thereby authorizing the descent, in the direction of arrow 26, of the lifting member 6.
  • the rear of the stack is still supported by the support member 13 of the back of the box 15 and, as soon as it continues to run in the direction of arrow 22, the support member 12 from the back of the stack 11 will come against the back of the sheet 15 thus supporting the back of the stack 11, as shown in FIG. 5 with the help of which the arrival of a new sheet to be stacked 27 is shown.
  • Figure 6 is a side view of the support members of the front of the stack and boxes.
  • the support member at the front of the stack comprises a comb 17 fixed with the aid of the screws 30 to a tubular cross member 31, each of the ends of which is attached to a lever 32 provided with two rollers 33 guided in a slide 34.
  • the rollers 33 are mounted against the lever 32 using the pins 35.
  • the back and forth movement of the comb 17 in the direction indicated by the double arrow 36 is generated by a cam (not shown).
  • This cam transmits a pendular movement, according to arrow 37, to an oscillating lever 38 pivoting around the shaft 39, this using a pull bar 40.
  • One end of the oscillating lever 38 is connected by an axis 41 to the pull tab 40, while the other end is connected to the lever 32 by a slide 42 in which engages a roller 43 fixed on said lever 32.
  • the lifting member 6 consists of a set of several levers 45 placed side by side across the width of the stacking device.
  • the levers 45 have one of their ends fixed to the transverse shaft 51 by means of a key 52, while their other end is provided with double rollers 53 (see FIG. 9).
  • the transverse shaft 51 is driven by an oscillating movement making it possible to pass the double rollers 53 from a position 6 ′ to a position 6 "’.
  • the movement of the transverse shaft 51 is produced from a device cam and lever (not shown) .As shown in FIG. 9, the levers 45 are arranged so that the double rollers 53 are aligned so as to support the belts 2 of the lower conveyor 1.
  • the boxes arriving in the stacking area in the direction indicated by the arrow 53 and coming to be stacked therein will be evacuated in successive packages from the top of the stack using a conveyor 54 composed of several belts 55 placed side by side across the width of the front stop 18.
