Definitions

  • the present invention relates to a receiving device and ejection of flat elements into a machine working them, especially in a packaging production machine intended for the manufacture of boxes in cardboard from sheet material or web.
  • Such machines include several stations placed one after another which typically allows the printing of the material used, cut it into a given shape using a rotary tool by example, and then eject the unwanted waste resulting from the cutting, and on the other hand all the cuts that happen to be no comply before collecting the other box cutouts in a station reception.
  • the sheets or cardboard strips worked can generally contain in their width several poses or cuts of identical boxes which each represents the shape and the developed surface of the manufactured packaging.
  • the number of poses that can be arranged side by side of course depends on the width of the support worked, but also the format maximum allowed by the machine and the size of the cutouts boxes.
  • these cutouts of boxes are arranged, in the receiving station, in rows of parallel sheets on strips Conveyor.
  • This tablecloth arrangement that is to say, so that the cuts overlap each other, is obtained by the fact that the bands conveyors advance more slowly than sheets or cardboard Power. So are formed as many rows of layers as there are poses in the width of the worked support.
  • the tablecloths are then regularly picked up by a stacker device to form piles who will eventually be evacuated on a cart, or by another carrier to bands, to a storage station for example.
  • the second carrier When the front part of the water table includes enough leaves to create a stack of a number of leaves, the second carrier lifts slightly above the plane of the first, and carries at an accelerated speed the corresponding portion of the sheet to pour it on a plate against a stop along which will be formed said stack of leaves.
  • this plateau goes down as measuring the stacking of the leaves so that the height of fall of the leaves be constant to ensure proper stacking.
  • the stack of leaves must be lowered to an exit level where it will be evacuated from the plateau before the latter can go up to be able to receive the next stack of leaves.
  • the second carrier has been downgraded then returned to its original position under the new front of the tablecloth not stop moving forward thanks to the continuous training of the first carrier.
  • Another device for forming stacks of sheets from of elements arranged in the form of sheets is described in document CH 633'761. It includes several carriers each formed of a carpet rolling conveyor occupying the entire width of the machine. On this width, several parallel sheets of box cuttings can be placed there.
  • This device also allows to receive and stack box blanks without decrease the rate of production of the machine associated with it by a braking member which will block the advance of the plies. This blockage will have for effect of temporarily increasing the thickness of the layers.
  • the last carpet transporter is arranged so that it can rotate around its tree of control, which allows, if necessary, to deflect the trajectory of the tablecloths on another conveyor belt evacuation.
  • GB 2'074'990 discloses another device for to deliver a certain number of leaves from a continuously circulating aquifer through a receiving station.
  • the device as described in GB 2'074'990 is formed of two telescopic conveyors put end to end.
  • Each conveyor is formed of an endless belt rotating around a plurality of rollers or rollers. The rotation speeds of these belts are independent of each other.
  • the front end of the first conveyor and the rear end of the second conveyor, which faces it, are mounted on the same carriage that can move longitudinally from front to back in the direction of movement of the sheet.
  • said carriage moves downstream and the speed of the second conveyor is increased to quickly release the second conveyor from its loading and thereby create a sufficient time interval to be able to evacuate the battery.
  • this device suffers from a first defect related to the size of the carriage which is necessarily dependent on the length of his race. Indeed, as conceived in this invention, it is possible find that the length of the trolley must in all cases be greater than the maximum length of its displacement. If we want to achieve higher production speeds it is also necessary to increase the moving the carriage, which leads to the arrangement of a carriage always longer and more and more imposing. Another flaw of this device results from repeated movements of the carriage. To be able to ensure the most long break possible, it is essential that the return of the trolley be done as quickly as possible.
  • this carriage also represents an important mass in movement which, on the one hand, requires a powerful mechanism for movement then braking, and which on the other hand must be controlled by a massive surrounding supporting structure. Moreover, the inertial force of this trolley continually generates strong jerks in the frame of the machine. All of these stresses and mechanical constraints desirable require a realization provided with heavy equipment, bulky and expensive.
  • the present invention aims to overcome the disadvantages mentioned above by providing a device for receiving and ejecting flat elements that is fast, economical, universal and easy to use.
  • this device must of course be able to be produced at a lower cost, but must also avoid any waste by quickly sorting the elements that meet the quality criteria of those with defects and that must be ejected from the production line.
  • the universal term we intends to provide a device that can be suitable for a variety of products of different formats and ensure simplicity of adaptation for be able to work with each of these products reducing as much as possible the times devoted to the settings of the receiving device between two sets of different works.
  • the object of the present invention must be able to be easily adaptable to receive large cutouts boxes, such as 1 or 2 blanks occupying the entire width of the machine, only for smaller cutouts of boxes distributed in large number (for example 10) in the width of the machine.
  • This device must also to be able to eject quickly, with less waste, all the Box cutouts that do not meet the required quality criteria. It will be noted that to respond effectively to this last condition of speed, it is already excluded to want to think about performing such a sort sheet to before they have been tabled.
  • the subject of the present invention is a device for receiving and ejecting according to claim 1.
  • FIG. 1 represents a diagrammatic elevational view of a device 20 for receiving and ejecting flat elements, such as sheets of carton 2, in a first situation illustrating the displacement of a sheet 22 of sheets 2 upstream downstream in the longitudinal direction of the machine according to the direction given by the arrow 1.
  • a very tight sheet of leaves such as the tablecloth 22 in the device 20, can not be directly formed from sheets 2 scrolling behind each other at very high speed.
  • the device 20 of reception must first be preceded by a unit first web 12 of sheets 2, more spaced than those of the web 22, between a conveyor belt 13 driven at a reduced speed by a roller 14 and a series of pressure rollers 15 which maintain and brake the sheets 2 against the conveyor belt 13 when they arrive and superimpose at high speed in unit 10.
  • the sheet 22 is formed on a second conveyor belt 23 making part of the device 20 for receiving and ejecting the sheets 2.
  • This carpet transporter 23 occupies, like all conveyor belts of this device, the whole width of the machine. It is set in motion by a roller 24 which rotates at a speed lower than that of the carpet trarisporter 13, around a plurality of rollers or rollers of references 25, 26, 27, 28 and 29.
  • the sheet 22 then advances on a third conveyor belt 33 rotated by a another roller drive 34 which, like the other means of training, is totally independent.
  • the conveyor belt 33 rotates, in the direction of the arrow 1, around other rollers or rollers of references 35, 36, 37, 38 and 39.
  • a stacker 40 which collecting the sheets 2 of the sheet on a plurality of ramps 41, adjustable in the width of the machine, to form a stack 42 which, as illustrated in FIG. FIG. 1 will finally be evacuated out of the device 20 and the stacker 40 in the direction of the arrow 4 by one or more belts 43 equipping each of the ramps 41.
  • the stacking of the sheets 2 takes place on the ramps 41 by moving the downstream end of the conveyor belt 33 in the plane vertical so that the drop height of the leaves 2 on the top of the stack is constant.
  • the roller 36 is secured to an elevator 50 consisting of a frame 51 that can move vertically as illustrated by the double boom 3.
  • This frame 51 is fixed on each of its sides to a chain 52 suspended and stretched by chain wheels 53.
  • the training of the chain is via a motor 54 coupled to one of the chain wheels 53.
  • FIG. 2 shows a simplified schematic view of the device as shown in Figure 1.
  • FIG. 2 shows a simplified schematic view of the device as shown in Figure 1.
  • this second figure are illustrated four rows 9 of parallel sheets of sheets that progress in the direction of the arrow 1 of the first conveyor belt 13 to the others conveyor belts 23 and 33 before coming to pile up in separate piles on the belts 43 ramps 41.
  • the other three rows are essentially represented by their outline.
  • the return rollers of the ends conveyor belts are here replaced and simply represented by their axis drawn in dotted line.
  • FIG. 3 represents, in a view similar to that of FIG. the device according to the invention in a second situation different from that illustrated in Figure 1.
  • the illustrations given by these two figures 1 and 3 are to better understand the operation of the device of this invention that will be described here.
  • One of the objectives stated in all recent reception devices is to be able to create piles of one number of leaves without interrupting the continuous flow of production sheets delivered upstream by the printing machine.
  • the incessant production of leaves 2 is illustrated by the unit 10 which continuously creates the moving web 12. On the conveyor belt 23, this last is simply narrowed into a sheet 22 by reducing the speed conveying.
  • the device of this invention has a drive mechanism 60 and interruption of tablecloths which allows to vary the useful lengths of conveyor belts 23 and 33.
  • This mechanism occupies, in the device 20, a central place located between the arrangement of conveyor belts 23 and 33. It consists of two trolleys, one upper 61 and the other lower 62, which can move horizontally from upstream to downstream and vice versa.
  • FIG 4 illustrating a vertical section along line IV-IV of the Figure 1, provides a better understanding of the operation and layout of the drive mechanism 60 located between the two main structures that constitute the frame 70 of the device 20.
  • conveyor belts and sheets of leaves have not been represented.
  • the return rolls 27 and 37 are mounted crazy between the vertical sides of this cart.
  • the lower carriage 62 supports the rolls of references 29 and 39. These are each mounted idle on a pair of pneumatic cylinders 63 which are fixed against the inside of the carriage 62. The arrangement of these cylinders makes it possible to compensate, independently, for the lack of voltage appear in the conveyor belts 23 and 33 when the carriages 61 and 62 are moving.
  • the carriages 61 and 62 slide between the frame 70, for a side to jaws 64 fixed against one side of the carriages and sliding each along a rail 65 secured to said frame, and for the other side to means of rollers 66 fixed against the other side of the carriages 61, 62 and rolling each on a tread 67 relative to the frame 70.
  • the drive trolleys is made by the engagement of racks 68, reported against the inner sides of the trolleys in the lower part for the trolley 61 and in the upper part for the carriage 62, with a pair of wheels teeth 69 mounted on the shaft 71 of an electric motor 72.
  • the speeds and the accelerations of the carriages 61 and 62 can therefore be finely controlled thanks to the flexibility of the control of the electric motor 72.
  • a clamp 75 is closed on this sheet between the rollers 27 and 37 of the respective conveyor belts 23, 33.
  • This clamp is formed of a bar transverse 76 placed at the ends of two angled arms 77 parallel and pivoting about an axis of rotation 78 through the upper carriage 61. pinch the ply 22, the two crank arms 77 pivot upwards and the bar transverse 76 compresses the sheet against a series of support rollers 79 arranged at will above the web 22 between the rollers 27 and 37.
  • the ramps 41 are generally arranged in a normal horizontal position allowing the reception of these sheets. It will be recalled here that there are so many batteries 22 there are rows 9 of tablecloths on conveyor belt 33 which simultaneously, are formed on the belts 43 of the parallel ramps 41. However, if a printing defect has for example been found on the sheets from one or other of these rows 9, the ramp or ramps 41 allocated to this row of defective sheets will go or will be able to be pivoted down by one or more pneumatic cylinders 44 even before the beginning of the stacking leaves. Therefore, only the web 32 of the row that contains leaves defective will be directly dumped from the stacker onto an evacuation mat the striker 90 placed transversely to the direction of movement of the webs. This situation is illustrated in Figure 5 where only the downstream part of the device of the The present invention is illustrated.
  • Figures 6 and 7 show in detail the mechanism that allows the times the tilting of one of the ramps 41 and the rotational drive of its belt 43.
  • Figure 6 is a partial sectional side view of this same ramp 41 along line VI-VI of Figure 7.
  • the illustration of Figure 6 presents the ramp 41 in two different positions, one horizontal line continuous, and the other vertical or tilted down in dotted lines.
  • This ramp consists of a U-shaped plate 45 reversed, as best seen on FIG. 7. Rollers 46, mounted on roller bearings, are fixed on this plate. free balls in rotation, around which runs the belt 43.
  • This belt is in permanent contact with a ring 47 positioned and fixed on a tree expandable drive 48 whose diameter can be increased, thus allowing to hold therein firmly said ring 47.
  • the expandable shaft 48 When the expandable shaft 48 is put in rotation, it also drives the ring 47 which, by contact, makes it possible to turn the belt 43.
  • a ball bearing 49 is mounted of each side of the ring 47, on a flange 94, in a groove machined on every blank of this ring. Part of this ball bearing 49 is rendered integral with the ring 47, while the other part, fixed to the flange 94, of this same ball bearing is made integral only the sheet 45 which constitutes the armature of the ramp 41. Thanks to the function of this ball bearing and thanks to its arrangement as described above, the plate 45 can then be rotated down or up by the jack 44 in a completely independent way the rotation of the belt 43 and its drive system.
