- the treatment tool is carried by at least one transverse carrier shaft driven in rotation by a shaft motor which is distinct from said at least one drive motor, to the fact that the means of drive are able to drive the sheets at a substantially constant drive speed between the input and the output of the machine and the fact that the machine has a suitable control unit, depending on said forward speed and the information relating to the position of a sheet in the processing area, to control the shaft motor so that, for processing this sheet, the tool is in contact with a predetermined region of the sheet and is driven by a processing speed whose tangential component is equal to said driving speed.
- the invention therefore proposes to drive the sheets at a substantially constant speed, without stopping phase.
- the tool intended for making the cuts or the transverse folds is carried by the carrier shaft which is arranged transversely with respect to the direction of drive of the sheets and which is driven by a shaft motor which is specific to it.
- the machine control unit knowing the speed at which the sheets are driven, the position of the tool on the transverse carrier shaft, the position of a sheet in the treatment zone and the positions of the cutouts or folds to be made in this sheet, control, not the sheet drive means, but the shaft motor of the carrier shaft so that, when processing the sheet, the tool is precisely in contact with the region of the sheet in which a fold or a cut must be made, and then be animated with a processing speed equal to the driving speed.
- the invention provides, not for wedging the drive of the sheets on a predetermined position of the processing tools, but rather, using an electronic control unit, for wedging the positions of the tools. and their speed relative to the sheet and its speed of drive.
- the shaft motor must be sufficiently reactive and flexible so that its speed can increase and decrease in a very short period of time to settle on a precise value which is that of the leaf drive.
- a positioning motor such as a multi-pole axis motor, which delivers a substantially constant torque both at low speed and at high speed may be suitable.
- the machine comprises a carrier shaft with angular tool adjustment comprising a hub, a holder fixed tool secured to this hub and a mobile tool holder secured to a mobile support which cooperates with the hub by means of position adjustment means allowing the angular position of the tool holder to be adjusted ' movable relative to the door -fixed tool.
- a carrier shaft with angular tool adjustment comprising a hub, a holder fixed tool secured to this hub and a mobile tool holder secured to a mobile support which cooperates with the hub by means of position adjustment means allowing the angular position of the tool holder to be adjusted ' movable relative to the door -fixed tool.

- the mobile support comprises at least one ring on which the mobile tool holder is fixed according to a second cylinder generator, this crown being coaxial with the hub, having an internal toothing and extending, in the region of the first generator, in a space formed between the exterior surface of the fixed tool holder and the hub
- the position adjustment means comprise an axis with pinion, which is disposed between the hub and the crown by cooperating with the internal toothing of this crown and means for driving the pinion axis in rotation, so as to rotate the crown relative to the hub and thus adjust the angular positioning of the second generator relative to the first generator.
- the carrier shaft comprises at least one tool holder equipped with quick attachment means for a tool, which comprise a longitudinal fixing groove located on the outer surface of the tool holder, at least one of the longitudinal edges of this groove being mobile and being delimited by a movable wedging piece between a locking position in which it defines with the opposite edge a retaining profile capable of retain a fixing rib having a complementary profile, and an unlocking position in which this edge is spaced from the opposite edge to allow the introduction of the fixing rib in said groove, by a radial displacement of this rib towards the axis of the bearing tree.
- the machine comprises a multi-tool carrier shaft capable of carrying at least first and second angularly spaced tools and the control unit is capable of controlling the shaft motor of said multi-tool carrier shaft according to a cycle comprising a processing phase by the first tool, in which said first tool is in contact with a first determined region of a sheet situated in the processing area of the machine and is driven by a tangential speed equal to the driving speed of this sheet, a positioning phase during which the multi-tool carrying shaft is driven to position the second tool in a situation of processing a second determined region of the sheet and a processing phase by the second tool, in which the second tool is in contact with said second region and is driven by a tangential speed equal to the drive speed.
- the angular tool-adjustable carrier shaft comprising a fixed tool holder and a mobile tool holder
- this carrier shaft rotates at the same speed (which, converted to tangential speed is equal to the speed of driving the sheets in the machine), during the treatment phase with the first tool, during the positioning phase and during the treatment phase with the second tool.
- the angular spacing between the two tools corresponds to the distance between the two treatment zones in which the two tools must act respectively.
- the positioning can, however, take place at a speed somewhat different from the speed at which the sheets are fed.
- the multi-tool carrier shaft can also carry different tools in determined zones and be driven during the positioning phase at a speed higher or lower than the speed of driving the sheets to wedge the second tool in the good position for the treatment phase with this second tool.
- the machine includes means for moving the multi-tool carrying shaft away from the path for advancing the sheets in the treatment zone during the positioning phase.
- the multi-tool carrying shaft can carry 3 or 4 angularly spaced tools, an intermediate tool being interposed between the first and the second aforementioned tool, for example to be used optionally.
- the multi-tool carrying shaft is driven at a speed corresponding to the speed of driving the sheets for the treatment phase with the first tool, is moved away from the path of advancement of the sheets and, in this situation, can be moved quickly to position the second tool in a position to process the second determined region of the sheet, without the intermediate tool coming into contact with the latter.
- the drive means cooperate with adjustable position drive rollers which are mounted on roller supports and the machine comprises means for adjusting the positions of these supports transversely to the drive direction. sheets in the machine. It is desirable to arrange the drive rollers in positions determined according to the width of the sheet, measured in the transverse direction.

- Figure 2 shows a blank processed by the machine from a full sheet.
- This blank 20 has cutouts 22 and folds 24 which are arranged transversely to the direction F of advancement of the sheet in the machine.
- the tools of the processing units U1 and U2 located in the processing area T of the machine allow these cuts and folds to be made. These tools include cutting tools or knives which form the cutouts 22 and tools to repress or repressors which form folds 24.
- the blank shown in FIG. 2 also has folds
- the blank also has specific cutouts, for example orifices 28 used to form handles in the packaging, which are produced in one of the processing units U1 or U2.
- the drive means of the machine include disc-shaped drive rollers which are rotated. We see for example in Figure 1, at the entrance of the machine, lower drive rollers 30 and 32, and upper drive rollers 34 and 36. Similarly, at the outlet, the drive means 18 have lower rollers 38 and 40 and upper rollers 42 and 44.

- the input zones E, treatment T and output S can be located in separable modules, in which case the main motor M50 directly drives a shaft A50, for example located in the treatment zone, which itself even is coupled by means of the Oldham joint type to driven shafts
- A50E for input and A50S for output are identical to A50E for input and A50S for output.
- Each of the processing units U1 and U2 includes a carrier shaft which carries processing tools. We first describe the unit
- carrier shaft with angular tool adjustment with its carrier shaft 52, hereinafter referred to as carrier shaft with angular tool adjustment.
- This shaft is located above the plane P of advancement of the sheets in the machine and it cooperates, by means of the tools which it carries, with a counterpart shaft 54 situated under this plane.
- This counterpart shaft carries a coating 56, for example of a material such as polyurethane, sufficiently flexible to allow the tools to fulfill their functions, for example by folding or cutting the sheet.
- a counterpart shaft 54 ′ is located under the carrier shaft 62 of the processing unit U2.
- the counter shafts, as well as the lower drive rollers, can be moved vertically to adapt to sheets of different thicknesses.
- the counterpart shafts can be rotated in the same way as the drive means, for example using the main motor M50. However, they are advantageously driven by an M54 auxiliary motor, for example an asynchronous motor with frequency converter, which is controlled to drive the sheets at the same speed as the drive means, i.e. the speed tangential of the counterpart shafts is the same as the tangential speed of the drive rollers, despite their different diameters.
- an M54 auxiliary motor for example an asynchronous motor with frequency converter
- the transverse carrier shaft 52 is rotated by a shaft motor M52 which is separate from the motor or motors of the drive means and the counterpart shafts. This is for example an asynchronous motor, a brushless motor, or so general, of a positioning motor.
- the shaft 52 is coupled to the output of this motor by a drive pin 53.
- the machine comprises a control unit UC which, according to information relating to the position of a sheet 12 in the processing zone T, controls the shaft motor M52 by a command line L52 such that, for the treatment of this sheet by a tool carried by the shaft 52, this tool is in contact with a predetermined region of the sheet and that it moves at the same tangential speed than the leaf speed.
- a control unit UC which, according to information relating to the position of a sheet 12 in the processing zone T, controls the shaft motor M52 by a command line L52 such that, for the treatment of this sheet by a tool carried by the shaft 52, this tool is in contact with a predetermined region of the sheet and that it moves at the same tangential speed than the leaf speed.
- the control unit knows the speed of the drive means 14, 16 and 18. For example, by a control line L50, it controls the main drive motor M50. In addition, it receives information from a speed sensor C50, for example a tachometer integral in rotation with one of the shafts of the drive means, by an information input line LE50. It can thus adjust its control of the M50 engine.
- a control line L50 it controls the main drive motor M50.
- a speed sensor C50 for example a tachometer integral in rotation with one of the shafts of the drive means, by an information input line LE50. It can thus adjust its control of the M50 engine.
- She also knows the position of a sheet in the machine. To do this, it receives information delivered by position sensors such as the photocells C1, C2 and C3 successively arranged on the path of advancement of the sheets, and which are connected to it by information input lines, LC1, LC2 and LC3 respectively.
- position sensors such as the photocells C1, C2 and C3 successively arranged on the path of advancement of the sheets, and which are connected to it by information input lines, LC1, LC2 and LC3 respectively.
- the sheet 12 is detected at the input by the sensor C1 and is optionally retained by a movable stop 60.
- the stopper 60 retracts and the sheet is pinched between the lower and upper coaches, such as the rollers 32 and 36.
- the sensor C2 is arranged downstream of the sensor C1, for example just downstream of the rollers 30 and 34 and detects the arrival of the sheet. This allows, if necessary, to correct the speed of the motor M50 or to correct the data used to control the motor M52 if, due to possible slippage, the speed of movement of the sheet between the sensors C1 and C2 is not not strictly equal to the speed of the drive means.
- control unit knows precisely the speed of advance and the position of the sheet in the machine. Consequently, depending on the MP setting means entered in the control unit to memorize which treatment (cutting, fold) must be applied to which region of the sheet, the latter can control the motor M52 independently of the drive means. so that he positions his tools in the right place, at the right time and at the right speed.
- the tool carrying shaft 62 is called the multiple tool carrying shaft. This shaft 62 is disposed above the plane P in the treatment zone and cooperates with the counterpart shaft 54 'similar to the shaft 54.
- the shaft 62 is rotated by a motor M62, for example a motor analogous to the motor M52 of the shaft 52 and which, like the latter is distinct from the motor or motors of the drive means and counterpart shafts.
- the motor M62 is controlled by the control unit UC, by a control line L62, to calibrate the speed and the position of the shaft 62 so that the tools which it carries cooperate with the leaves in the right place, at the right time and at the right speed.
- the control unit knows the speeds of the shafts carrying tools 52 and 62 and can, according to these data, modify its control of the motors M52 and M62.
- a line LE54 also connected to sensors, it still knows the speed of the counterpart shafts 54 and 54 'and it can therefore correct the control of the motor M54.
- the sheets are fed into the machine at a substantially constant drive speed.
- the control unit UC knowing this speed and the position of the sheet, controls the motor M52 or the motor M62 between a waiting phase, in which its speed is zero or substantially zero, a positioning phase in which its speed is different from the drive speed (it is generally higher) in order to correctly position the ad hoc tool with respect to the position which the region of the sheet to be treated by this tool will reach.
- the positioning phase is followed by a processing phase in which the motor M52 or M62 is controlled when this region of the leaf is opposite the shaft 52 or 62. In this processing phase, the tangential speed of this tool is equal to the forward speed to perform the desired treatment.
- a new waiting phase follows the treatment phase.
- This cycle is repeated one or more times per sheet, depending on the treatment (s) (cuts, folds ...) to be applied.
- the motor 52 or 62 undergoes a very rapid acceleration or deceleration phase.
- the configuration means correspond to a type of treatment chosen from different possible treatments, each corresponding to a type of packaging to be manufactured (dimensions of the sheets, shape of the packaging after folding and hanging of the sheets, positioning accordingly of the folds and of the cuts ).
- the angular tool-adjustable carrying shaft 52 carries two angularly spaced tools. As best seen in Figure 7, it includes a shaft hub 64 which is coupled to the drive shaft 53. It also includes a fixed tool holder 66 which is integral with the hub 64 and a tool holder mobile 68 which is integral with a mobile support 70 constituted, in this case, by one or more mobile crowns.
- Figure 7 shows the tools carried by the two tool holders 66 and 68 angularly spaced by an angle ⁇ but, in Figures 1 and 8, for the convenience of the drawing, these two tool holders are diametrically opposed.
- the fixed tool holder 66 is arranged according to a first cylinder generator G1 by being fixed to the hub, for example by fixing and bracing shoes 72.
- the mobile tool holder is fixed to the crown 70 by being arranged according to a second cylinder generator G2.
- the tool holders 66 and 68 are arranged so that their respective tool-carrying surfaces S66 and S68 are on the same cylindrical surface. Due to the thicknesses of the tool holders, these surfaces S66 and S68 are projecting radially with respect to the cylindrical surface S52 of the rest of the shaft 52, in particular determined by the crown 70. It follows that when a portion of the shaft 52 located between the tool holders 66 and 68, is located opposite the sheet being processed, this portion is not in contact with said sheet, so that it is not necessary to 'move the shaft 52 away from the sheet advancement path.
- the crown 70 has an internal toothing 70A on which meshes a pinion pin 74 disposed between the hub 64 and the crown.
- this axis is carried by a bearing 76 capable of sliding on the surface of the hub 64.
- a space 78 is provided between the outer surface S66 of the fixed tool holder and the hub 64 to allow the passage of the circular crown 70. In the present case, this annular space is produced in the external face of the shoe 72.
- several crowns 70 of similar conformation and several shoes 72 can be arranged on the along the hub 64.
- the pinion axis 74 when the pinion axis 74 is rotated, it displaces the crown 70, that is to say that it also displaces the mobile tool holder.
- the dimensions of the shoe 72 determine the minimum space that it is possible to obtain between the fixed and mobile tool holders.
- the means for driving the pinion axis 74 in rotation comprise a toothed wheel 80 coaxial with the drive axis 53 of the shaft 52 and freely mounted around this axis ( Figures 3 and 8) .
- This toothed wheel meshes with the pinion pin 74 and cooperates with rotation drive means.
- the end of the axle 74 carries a toothed drive wheel 82 which cooperates with the wheel 80.
- the carrier shaft 52 or 62 advantageously comprises a tool holder which is equipped with quick attachment means for a tool. In this case, this is the case of the shaft 52 and we understand better the shape of these means in FIGS. 7 and 9 to 10.
- the retaining profile of the groove 84 can be a dovetail profile or a T-profile.
- the back of the tool 88 has a fixing rib 90 having a complementary retaining profile, which can therefore be 'embed in the groove.
- the actual tool (for example formed by two knives 94) is carried by a plate or base 92 whose curvature delimits a cylindrical surface so that, during the rotation of the carrier shaft for the treatment of a sheet in the machine, the distance between the tool and the plane P remains constant.
- the machine comprises cutting tools such as the tool 88 represented in FIGS. 9 to 11 which each include a cutting part (knives 94), and tools to push back such as the tool 88 'in FIG. 11 which include each a delivery part (rib 96).
- These tools further include a base 92 bearing the fixing rib 90.
- the shafts 52 and 62 can each carry several tools, and can therefore be driven according to a cycle comprising a treatment phase with a first tool, a positioning phase and a treatment phase with a second tool.
- the positioning phase can simply consist in continuing to train it at the same speed between the two processing phases.
- the shaft 62 also carries several angularly spaced tools, but its cylindrical surface S62 is, in the working position, close to the plane P of advancement of the sheets.
- the tools can be mounted on simple plates which are screwed into threads. radials formed on the cylindrical surface of the shaft 62. It can be seen in FIG. 4 that the shaft 62 carries, for example, a tool 100 having a knife intended to make orifices such as the openings 28 in the blank of FIG. 2.
- this shaft 62 is shown diagrammatically in cross section and it carries four tools numbered from 100 to 103, which are angularly spaced. It has been indicated in these figures, a sheet 12 disposed on the plane P of advancement of the sheets. After the processing of a first determined region of the sheet R1 by the first tool 100, and before the processing of a second determined region of the sheet R2 by another tool, for example the tool 103, the shaft 62 is driven according to its positioning phase. Insofar as its cylindrical surface S62 is too close to the sheet in the working position, this shaft 62 is discarded the path of advancement of the sheets in the treatment zone during the positioning phase.
- the means controlling this spacing are shown in Figures 4 and 12A to 12D. They comprise a spacer shaft 106 which carries at least one eccentric 108.
- the carrier shaft 62 is mounted on a movable axis 110 which is supported by the spacer shaft 106 via the eccentric.
- the shaft 106 is fixed relative to the frame of the machine and the eccentric 108 is formed by a roller which is connected to it in an eccentric position.
- This roller 108 is rotated by a spacer motor M108, around its geometric axis.
- the roller 108 moves around the center of the shaft 106 through the different positions shown in Figures 12A to 12D.
- the axis 110 of the shaft 62 is supported by the spacer shaft
- the roller is connected to the shaft 62 via a system of connecting rods 112.
- the shaft 106 extends transversely inside of the treatment zone and, at each of its ends, it carries a roller 108 rotating at the first end of a connecting rod 112, the second end of which is connected to the shaft 62 while being articulated with respect to it.
- this connection is indirect and uses a lever 114 as indicated below.
- the movable axis 110 is integral with a lever which carries a counterweight intended to facilitate the upward movement of the carrier shaft.
- each connecting rod 112 is articulated by its second end on a lever 114, one end portion of which directly carries the axis 110 of the shaft 62 and the opposite end of which carries a counterweight 116.
- the levers 114 are pivotally mounted around a pivot axis A114.
- the counterweight 116 is balanced with respect to the shaft 62 so that the force required to raise this shaft 62 is low.
- the shaft 62 is lowered so that the tool 100 comes into contact with the sheet 12.
- the motor M108 is controlled by the control unit UC, to which it is connected by a control line L108, so as to raise the carrier shaft 62.
- the motor M62 is controlled by the control unit so as to bring the tool to perform the following processing, for example the tool 103, in a position to carry out this processing.
- Figures 12B and 12C show this positioning phase.
- the control unit is informed of the speed of the motor M 108, to adjust it accordingly.
- the drive means include drive rollers such as those of the relay 16, the spacing of which in the transverse direction to the machine need not be modified.
- stations 14 and 18 may include rollers fixed in translation. However, in some cases, it may be necessary to change the positions of the rollers.
- FIG. 13 shows a roller 30. Like the other adjustable rollers, it is mounted on a roller support 120 which can be moved transversely relative to the drive direction F.
- the machine comprises an adjustment belt 122 which is driven transversely to the direction F. This belt is driven by means such as a motor M 122 (FIG. 3).
- each roller support 120 can be coupled with this belt to allow the movement of the rollers or, on the contrary, be uncoupled with respect to the belt and locked to keep the rollers in position.
- each roller support 120 comprises a coupling pad 124 and a coupling counterpart 126 which are arranged on either side of the belt 122 (on one of the arms of the loop which it forms).
- the shoe 124 can be placed in a coupling position (FIG. 14) in which it presses the belt 122 against the counterpart 126, so that the roller support 120 and the roller that it carries are moved with the belt.
- This shoe can also occupy an inactive position ( Figure 15), in which it is moved away from the belt.
- Each roller support 120 further comprises a stop shoe 128 which can be placed in a stop position (FIG. 15) in which it cooperates with a fixed locking piece 130 to make the roller support 120 integral with this part and block it in the desired position, and which can be placed in an inactive position (FIG. 14), in which it is moved away from this
- the machine comprises means for controlling the coupling shoe 124 and the stop shoe 128 which are capable of placing the coupling shoe in its coupling position when the stop shoe occupies its inactive position and which are suitable placing the stop shoe in its stop position when the coupling shoe is in its inactive position.
- stop shoe 128 and the coupling shoe 124 can be arranged at each of the two ends of a rod 132 movable back and forth.
- This rod is for example controlled between its two positions by a pneumatic cylinder.
- the fixed blocking part can be constituted by a fixed belt which is stretched parallel to the strand of the belt 122 with which the shoe 124 cooperates, or by another part such as a fixed plate or the like. If necessary, it can be arranged between the shoe 130 and a counterpart 131 to be pinched between these parts in the stopped position.
- the roller support 120 is integral with the grooved drive axis 31. It indeed has a toothed wheel whose internal periphery meshes with this axis and which, itself, drives a system of toothed wheels for the transmission of the drive to the roller 30.
- the mechanical connection mode with the splined axis 31 allows the support 120 to be moved in translation along this shaft.
- the support 120 is carried by a console 134, which is itself supported by a support beam 136 arranged transversely to the direction F.
- the console 134 slides by ball slides 138 on the lower end of this beam.
- the pads 124 and 128, as well as the counterparts 126 and 131, are carried by an arm 134A of the console 134.
- the belt 122 is arranged vertically, the pad 128 cooperating with one of its horizontal strands (the lower strand) .
- Another arm 134B of the console 134 supports a cylinder 137 which serves to adjust the vertical position of the roller 30 relative to its support 120, to adapt this position to different thicknesses of sheets.
