Definitions

  • the present invention relates to a machine for receiving and stacking blanks of cardboard or similar material, of variable shape and format, cut one after the other, in a continuous web, by a cutting device located upstream of the machine, fed in "scales" on a conveyor, overlapping each other.
  • the present invention aims to adapt this stacking process in a machine allowing, depending on the number of blanks of a particular print, that is to say depending on whether it is to receive successive blanks forming part of a series of a large number or a small number of blanks either to form and automatically evacuate stacks of a predetermined number of blanks, to facilitate the subsequent recovery of the stacks of blanks, according to their use downstream , or to let the blanks come out continuously, one after the other, to allow easy manual recovery of the blanks.
  • this machine for receiving and stacking blanks of cardboard or similar material, of variable shape and format, cut one after the other, in a continuous sheet, by a cutting device located upstream of the machine, fed in "scales" on an endless conveyor belt, overlapping each other in such a way that the front edge of any blank is placed above a previous blank while its rear edge is in contact with the conveyor belt, said machine comprising a device for deflecting the blanks by at least 90 °, endless parallel movable belts extending between the outlet of the device for deflecting the blanks and a transverse stacking stop which stops the blanks successive which engage one after the other under the stack of blanks already formed, the blank deflection device comprising a drum of horizontal and transverse axis around which pass the co movable endless tracks extending up to the stacking stop, the conveyor belt being tangent to the drum, under the latter, and passing around a motorized drive roller and return rollers of horizontal axes and transverse, is characterized in that at least one of the def
  • the machine according to the invention is provided with a central control device which synchronizes the operation of the various actuating members, such as jacks, and which makes it possible to automatically initiate the release and lateral discharge cycle of a battery. when this stack has reached the desired number of blanks. Because the blanks constituting each stack arrive successively from below this stack, the height of the stacks is not limited.
  • the machine according to the invention thus offers the advantage that it can be used very conveniently in two different ways, namely by providing, at its outlet, a continuous line of blanks in "scales", in the horizontal and longitudinal direction, or by supplying, after deflection of the blanks, stacks of blanks of variable height, these stacks being removed laterally, which facilitates their subsequent use on packaging machines.
  • the first case that is to say with a horizontal outlet in the axis of the machine, is particularly interesting when it comes to short series of blanks; indeed, this avoids having to modify the machine settings.
  • the machine according to the invention lends itself equally ment well to the formation of stacks of blanks increasing in the horizontal direction (with deviation of the blank line by 90 °) or in an inclined direction of any angle greater than 90 ° relative to the horizontal direction of feeding blanks.
  • the machine according to the invention which is represented in FIGS. 1A and 1B, comprises an upstream conveyor belt 1, of the endless type, on the upper strand of which lans 2 overlapping one move from right to left. others.
  • These blanks 2 which can be, for example, blanks of cardboard precut to later form packaging and printed on their upper faces, form "scales" on the upper strand of the conveyor 1, in other words the front edge 2a of any blank 2 is placed above a previous blank 2 while its rear edge 2b, which is in contact with the conveyor belt, is located under the next blank 2.
  • These blanks 2 are obtained by cutting, upstream, a continuous sheet, by means of a cutting device of any known type. They constitute, on the upstream conveyor, a single longitudinal row or several parallel rows distant from each other.
  • the blanks 2 in "scales" are brought to a horizontal endless conveyor belt 3.
  • the upstream conveyor belt 1 and the intermediate conveyor belt 3 are both driven, at the same linear speed V, by a motor 4 coupled, by via a transmission mechanism 5, to rollers 6 and 7 respectively driving the upstream conveyor belt 1 and the intermediate conveyor belt 3.
  • transverse jogging device 8 of any known type, which comprises, by row of blanks 2, a pair of vertical and longitudinal plates 9, aminated with 'an alternating transverse movement and coming into contact with the longitudinal edges of the flanks 2, to align each row of flaps 2.
  • This device 11 is placed at the junction of the intermediate conveyor belt 3 and a downstream reversing conveyor 12 which comprises an endless conveyor belt 13 passing over an upstream deflection roller 14 of horizontal and transverse axis, which extends in manhole and at the same level as another downstream deflection roller 15, of horizontal and transverse axis, provided for the intermediate conveyor belt 3.
  • the device 11 which is provided for the separation of thin articles such as cardboard blanks, comprises a lower cleat 16, normally located, between the two rollers 14, 15, flush with the upper strands of the two conveyor belts 3 and 13 or under these strands and which can be lifted by a jack 17. Above the deflection rollers 14 and 15 is articulated, around a horizontal and transverse axis 18, a first pivoting lever 19 which carries, at its lower part, a horizontal plate 19a and which is urged clockwise, that is to say downwards, by a spring 22.
  • the device 11 also includes a second lever 20 which is also articulated around the axis 18, which carries at least one pressure roller or cylinder 23, disposed above the conveyor belt 13, and a stop 21 adjustable in height relative to the cylinder 23, and which can be lowered under the control of a jack 24
  • the first lever 19 is stopped, in s it is moved downwards, by an appropriate stop provided on the second lever 20.
  • a central control device causes the lowering, consequently of the supply to the jack 24, of the two levers 19 and 20 and consequently of the stop 21 and of the pressure roller or cylinder 23. Simultaneously the lower cleat 16 is lifted by the jack 17, this cleat in turn raising the blanks 2 by causing them to stop against the lowered stop 21 and letting the other blanks located forward move away.
  • the stop 21 thus stops the first blank of the following group of blanks, intended to constitute the next stack, thus forming an empty space or "hole" a in the row of blanks.
  • the jack 24 has lowered the pressure roller (s) 23 in contact with the last blanks 2 of the previous group to promote the drive of these last blanks of the previous group by the conveyor belt 13.
  • This conveyor belt 13 is then moved, after an adjustable time, at a speed V1 greater than the speed V of the intermediate conveyor belt 3, in order to avoid excessive accumulation of blanks against the stop 21, during the formation of the hole.
  • the stop of the line of blanks by the stop 21 is thus effected by "shearing” or breaking of the continuity in the vertical direction, and not by pinching this line of blanks.
  • the central control device causes the cleat 16 to be lowered and the stop 21 as well as the pressure roller 23 to be raised, which has the effect of releasing the first blanks from the following group which have been retained upstream of the stop 21, gradually stacking. These first blanks are held down by the plate 19a at the start of the ascent of the stop 21.
  • the next group of blanks 2 then continues its movement to the left, passing from the intermediate conveyor belt 3 to the downstream conveyor belt for deflecting the blanks 13 (180 ° reversal in this particular embodiment), this group then being separated from the previous group by an empty space or "hole" a.
  • the drive of the endless conveyor belt 13 is carried out by means of a motor 25 which is coupled to a drive roller 26 of the conveyor belt 13, by means of a transmission mechanism 25a.
  • the upper horizontal strand of the downstream conveyor belt 13 passes around the left half of the periphery of a turn drum 36, of horizontal and transverse axis, located above the conveyor belt 13 and rotated by the motor. 25, via an appropriate linkage mechanism not shown. It then passes over a first upper deflection roller 27 tangent to the upper part of the drum 36, then successively over a second upper deflection roller 28, located at the same level as the previous one but shifted to the left, a third deflection roller 29 lower, located under the horizontal strand of the belt 13, then on the drive roller 26 and on a lower tension return roller 31, with an adjustable position to adjust the tension of the conveyor belt 13, to return to the upstream return roller 14
  • the lower tension return roller 31 is carried by a pair of parallel arms 32 articulated around a horizontal and transverse axis, at their upper part, and which are actuated by a horizontal and longitudinal tension cylinder 33 mounted to the part bottom of the machine frame.
  • the first and second upper deflection rollers 27 and 28 for the conveyor belt 13 are rotatably mounted on a frame 34 which is pivotally mounted on the machine frame, around a horizontal and transverse axis coincident with that of the deflection roller lower 29.
  • the pivoting movement of the chassis 34 is controlled by a mechanism 30, provided on one side of the machine and which can be actuated manually or by a motor.
  • the frame 34 can be brought into a horizontal position, as indicated in the left part of FIG. 1A, and in this case the groups of blanks 2 come out horizontally, at the left or downstream end of the machine, being separated or not from each other by holes previously formed by the separation device 11 and without being turned over, in other words with the printed faces of the blanks facing upwards.
  • This horizontal position of the frame 34 is suitable in the case of short series of blanks or blanks having an irregular shape which do not lend themselves to automatic stacking.
  • the frame 34 can also be brought into a vertical position, as it is also shown in FIG. 1A. In this vertical position, the downstream part of the upper strand of the conveyor belt 13 is pressed against a set of parallel endless belts 35, passing around the left half of the turning drum 36.
  • the belts 35 can be constituted by cylindrical belts s 'engaging in grooves, in semi-circular cross section, of the drum 36.
  • the upper strand of the conveyor belt thus applies to half of the peripheral surface of the drum 36 located to the left of the vertical diametral plane and on which are wound the endless belts 35.
  • the cylinder 33 for adjusting the tension of the conveyor belt 13 is provided to take account of the variation in the length of the part of the conveyor belt 13 extending between the lower generator of the drum 36 and the first upper deflection roller 27, respectively in the two horizontal and vertical positions of the pivoting frame 34.
  • the jack 33 adjusts the position of the movable deflection roller 31 so that the conveyor belt 13 always has the correct tension, whatever the position of the pivoting frame 34.
  • the blanks 2 After their 180 ° reversal the blanks 2 are released at the upper part of the drum 36, at the place where it is tangent to the first upper deflection roller 27 of the conveyor belt 13. From this moment the blanks 2 which have thus been turned 180 °, are moved from left to right by the belts 35, in the direction of a stacking device 37 provided at the top of the machine. These blanks 2 are then presented with an arrangement in "scales" opposite to their arrangement at the lower part of the machine, that is to say that the front edge 2a of a blank 2 is placed under a previous blank and the rear edge 2b of the same blank 2 is placed above the next blank 2, as it appears in the drawing.
  • the blanks 2, thus turned 180 °, are moved by the upper strands of the belts 35 to a transverse stacking stop 38 forming part of the stacking device 37 and which can be retracted vertically under the belts 35, under the action of a mechanism controlled by a jack 39.
  • the machine may comprise, upstream of the stacking stop 38, at least one pressing roller (or plate) 49 mounted on a support 51 adjustable longitudinally, this roller being able to be pressed downwards by a cylinder or spring 52.
  • This roller 49 is intended to exert pressure on the blanks 2 located on the upper strand of the belts 35, in an appropriate position varying longitudinally as a function of the format of the blanks 2, to facilitate their introduction to the base of the battery.
  • the support 51 is also arranged to constitute a guide on the upstream side of the stack during its formation.
  • the central control device causes the supply of the jack 39, to lower the retractable stacking stop 38.
  • This stop 38 then releases the stack blanks formed against it, this stack being driven, by the belts 35, to the right in FIG. 1B, until it comes to meet a stop 42 for stopping the stacks.
  • the speed of the belts 35 has been reduced to the value V of the conveyor 3, so as not to transport the batteries at too high a speed, risking their deformation.
  • This stop 42 is located just after a lateral discharge device 43 comprising a set of rollers 44 extending longitudinally and which are carried by a support 45 movable vertically under the control of a jack 46.
  • These rollers 44 of the device lateral discharge 43 can be rotated on themselves by means of endless drive belts 47 which are in contact with the lower parts of the rollers 44 and which are driven by a motor 48 by means of a mechanism appropriate transmission.
  • the central control device causes the support 45 and the assembly of discharge rollers 44 to be raised, then the spacing of the evacuation stop 42 by means of a jack 42a, then the electrical supply of the motor 48 to rotate these rollers 44.
  • rollers 44 are lifted above the belts 35, they come into contact with the face bottom of the last blank of the stack formed, they lift this stack somewhat and by their rotation they cause the evacuation of the stack in the transverse direction on one side or the other of the machine. The stack of blanks can then be taken up by any handling chain.
  • the machine no longer includes the device 11 intended to form "holes" of separation between the groups of successive blanks subsequently forming individual stacks.
  • the blanks 2 arrive on the upper strands of the belts 35 by forming a continuous stream, the belt 13 then always moving at the same speed.
  • these blanks form, in contact with the stacking stop 38, a continuously increasing stack.
  • At least one horizontal blade 53 which can be moved horizontally and longitudinally, at above the stop 38, by a longitudinal cylinder 54.
  • This blade 53 with rounded tip, is intended to be introduced horizontally and longitudinally into the stack being formed, to separate it into two parts, namely a lower part P1 and an upper part P2.
  • a pusher 55 actuated by a jack 56 or any other suitable control device, and which is arranged, behind the stop 38, so as to raise the upper part P2 of the pile being formed, by its rear or right side which is opposite the end of the blade 53.
  • the spreader pusher 55 For the spreader pusher 55 to function properly, its inclination relative to the vertical must be between 15 and 30 °. Therefore, when feeding the jack 56, the spreader pusher 55 is moved up and to the left, it comes into contact with the right side of a blank of the stack being formed, and it lifts slightly this blank, as well as the upper part P2 of the stack. At this moment the jack 54 moves the blade 53 to the left so that this blade 53 engages between the lower part P1 of the stack comprising the blanks 2 arriving continuously, and the upper part P2 which comprises the packet of blanks resting on the blade 53. It is then possible to take up, by any appropriate means, the upper pack of blanks P2 which is thus separated from the lower pack P1 which constitutes a pile still being formed.
  • the separation device shown in FIG. 3 could also be used with a device no longer ensuring a 180 ° reversal, as it is shown in FIG. 1A, but simply a 90 ° deviation from the blank file (FIG. 4), thus forming an ascending blank file, or from another angle greater than 90 °, for example 120 ° (FIG. 5).
