Definitions

  • the present invention relates to a device for feeding a processing unit with a continuous web support.
  • the invention also relates to a station for supplying a transformation unit with a continuous band support, the transformation unit transforming the support stationary.
  • Such a station comprises a feeding device according to the present invention.
  • Such a processing unit of the support is a platen cutting press or a platen printing.
  • the invention also relates to a packaging production machine, integrating a feed station with a continuous web support and a subsequent support processing unit.
  • a packaging production machine is intended for the manufacture of boxes, which will be able to form packaging, by folding and gluing.
  • the production starts from an initial continuous medium, that is to say a blank tape, for example cardboard, which is unrolled continuously, printed by one or more groups printers, possibly embossed, then cut into a platen cutting press.
  • the poses or boxes obtained are then tabled, before being stacked in rows to form stacks in a receiving and palletizing station, for storage or transport out of the production machine.
  • a platen cutting press or a platen is a transformation unit that requires a temporary stop of the scrolling of the support during the transformation. Due to the continuous feed upstream, there is an accumulation of support in the form of an upstream loop.
  • a feeding station serves firstly to register the printing with the cutout longitudinally and laterally.
  • the other function of the feed station is to cyclically create and continuously control this loop which is lengthened during the stoppage due to the work of the press, which is shortened as soon as the food of the press resumes with a view to the subsequent transformation.
  • the Feed Station transforms the continuous scrolling of the media into intermittent scrolling at each work cycle of the transformation unit, while maintaining a constant media tension at the loop control level.
  • This device which is considered to represent the closest state of technology, comprises a first roller, called a drive roller, also known as a call cylinder or sensitive control, around which cyclically oscillates, towards the upstream then downstream, a second roll, called a satellite roll.
  • the satellite roller is mounted on two lateral levers pivoting on the axis of the drive roller.
  • the drive gear of the satellite roller is meshing with a toothed wheel integral with the axis of the first drive roller.
  • a rod is hooked by means of a bearing on the axis of the satellite roller and allows the latter to be pulled cyclically from upstream to downstream.
  • This device further comprises a counterweight, driven in rotation by a pinion from the toothed wheel of the axis of the first drive roller.
  • the counterweight is mounted on an arm pivotable about the axis of the first drive roller.
  • the counterweight is connected by a mechanism to the levers to oscillate in the opposite direction of the satellite roller.
  • the counterweight makes it possible to compensate the traction of the connecting rod on the axis of the satellite roller.
  • the counterweight has moments of inertia with respect to its central axis of rotation and with respect to the axis of the arm identical to those of the satellite roller.
  • a main object of the present invention is to develop a device for feeding a processing unit with a continuous web support.
  • a second objective is to provide a device for higher speeds for feeding the carrier and for processing the subsequent carrier.
  • a third objective is to make more precise the longitudinal and lateral register of the support between the supply and the transformation, thanks to a station comprising a feeding device.
  • a fourth objective is to design a device for a feed station avoiding the problems of the state of the art.
  • Still another object is to provide a packaging production machine incorporating a feed station and a web support processing unit, transforming the carrier intermittently.
  • the continuous web support is engaged and maintained between this main drive roller and this satellite roller.
  • the continuous web support cyclically moves from a constant speed to a zero speed, and vice versa from a zero speed to a constant speed, at the exit of the satellite roll.
  • the device is characterized in that the two lateral levers are secured to this main shaft.
  • the device is also characterized in that it comprises at least one electric drive secondary motor, able to oscillate the main shaft, the two lateral levers and the satellite roller.
  • upstream and downstream directions are defined with reference to the direction of travel of the continuous web support, in the longitudinal direction, before, inside and after respectively the feed device, the station feed, and the processing unit.
  • the rod mechanism of the state of the art is replaced by one or more secondary engines.
  • the counterweight has been removed, which reduces the inertia of the satellite roller and all moving parts.
  • the device has improved ergonomics, requiring little maintenance of moving parts. Due to the removal of many mechanical parts, the device and the station are less noisy and more reliable.
  • the device requires only a few adjustments, which avoids wasting tape media.
  • the changes of work and the set of adjustments are done by driving the main engine and the secondary engine (s).
  • Such a control makes it possible in particular to modify the speed of displacement of the support in band, the frequency and the amplitude of the oscillations of the satellite roller.
  • the data relating to these adjustments can be memorized and easily recalled for the execution of identical works.
  • the format is adjusted instantaneously by increasing or decreasing the amplitude of the oscillations.
  • the web support undergoes an acceleration in the longitudinal direction and not transversely as in the documents of the state of the art. Due to the compactness of the device, the length of the tape medium is reduced between the input of this device and the input of the transformation unit. This makes it possible to reduce the errors of positioning of the support in band, both longitudinally and laterally. This also makes it possible to reduce the aerodynamic phenomena occurring on the support strip which parasitize its trajectory.
  • the feeder is completely decoupled from the feed unit transformation, which makes it possible to control it in speed, in cadence, in format, etc., in a way different from this unit of transformation and thus to obtain more flexibility of use.
  • a station for feeding a processing unit with a continuous web support the transforming unit transforming the support stationary, is characterized in that it comprises a device having one or many of the technical features described below and claimed.
  • a packaging production machine is characterized in that it comprises a feed station, as described below and claimed, positioned upstream of a processing unit under the shape of a platen cutting press.
  • a packaging production machine (1) comprises in particular a feed station (2) and a processing unit, which is in this case a platen cutting press (3). Upstream of the feed station (2), the packaging production machine (1) has, as an example, printing units, as well as means for controlling the quality and the register.
  • the feed station (2) receives upstream a material or a continuous web support, which is in this case cardboard (4), arriving with a constant speed.
  • the feed station (2) delivers the same strip (4) downstream to the platen press (3) with an intermittent speed.
  • the platen press (3) cuts the web (4) and delivers webs (5).
  • the direction of advance or scroll (Arrow F in Figure 1 ) of the web (4) and the poses (5) in the longitudinal direction indicate the upstream direction and the downstream direction.
  • the device (9) comprises a driving main roller (12) rotating (T arrow in Figures 1, 2 and 3 ) on a main shaft (13).
  • the main shaft (13) and thus the main roller (12) are mounted substantially horizontally and perpendicular to the direction of travel of the strip (4).
  • the main roll (12) thus continuously drives the web (4) from upstream to downstream.
  • An electric drive main motor (14) rotates (T) the drive roller (12).
  • a satellite roller (16) is mounted while being parallel to the main roller (12).
  • the web (4) is engaged between the main roll (12) and the satellite roll (16) and is held there while being drivable (F) in the forward direction (see also the visible dashed line in Figures 1 and 3 ).
  • the strip (4) forms a path that is about three-quarters of a turn of the main roll (12) and half a turn of the satellite roll (16).
  • the satellite roller (16) is able to oscillate (Arrow O in Figures 1, 2 and 3 ) around the main drive roller (12), from upstream to downstream, and vice versa from downstream to upstream. Two extreme positions of the satellite roll (16) are shown in dotted lines in Figure 1 .
  • the oscillation frequency (O) of the satellite roll (16) causes speed variations of the band (4).
  • the band (4) can cyclically go from a constant speed (F) to a zero speed, and vice versa, from a zero speed to a constant speed (F).
  • F constant speed
  • F constant speed
  • the angular amplitude of the oscillations (O) of the satellite roller (16) generates different lengths of strip (4) introduced into the press (3). These lengths and therefore the angular amplitude of the oscillations (O) are chosen according to the format to be cut by the press (3) downstream. As an indication, the angular amplitude varies from ⁇ 9 ° to ⁇ 24 °.
  • the satellite roller (16) rotates in two bearings (17).
  • the two satellite bearings (17) are located at each end of the satellite roller (16).
  • the two satellite bearings (17) are each inserted in two lateral levers (18), thus located at each end of the satellite roller (16).
  • the two lateral levers (18) are mounted on and are secured to the main shaft (13).
  • the main shaft (13) is designed similarly to a stiffness or anti-torsion bar or cross member, so as to withstand significant stresses due to oscillations (O) and the weight of the satellite roller (16) and both side levers (18). The moving mass is thus reduced because it is arranged directly on the oscillation axis (O).
  • This anti-torsion cross is located closer to the axis of rotation, thus avoiding other deported inertia.
  • the main shaft (13), the two side levers (18) and the satellite roller (16) are driven from one or both ends, with very little biasing of the satellite roller (16).
  • the device (9) is very rigid with a low inertia in motion.
  • the device (9) comprises at least one electric drive secondary motor (19), able to oscillate (O) the main shaft (13), the two lateral levers (18) and the satellite roller (16).
  • the secondary motor or motors (19) may preferably be mounted coaxial with the main shaft (13).
  • the rotor of the secondary motor (19) can be secured to the main shaft (13).
  • the stator of the secondary motor (19) can be secured to the frame (22). This simplified construction makes it possible to eliminate the hyperstatism and to further reduce the number of bearings.
  • the device (9) may comprise two secondary motors, which may be able to rotate the main shaft (13), the two lateral levers (18) and the satellite roller (16). These two secondary motors can be arranged at each of the two ends of this main shaft (13). This solution is advantageous to avoid biasing one side of the main shaft (13) relative to the other side.
  • the main shaft (13) rotates in two bearings (21).
  • the two shaft bearings (21) are located at each end of the main shaft (13).
  • the two shaft bearings (21) are each inserted into a side face of the frame (22).
  • the main drive roller (12) rotates in two main bearings (23).
  • the two main bearings (23) are located at each end of the main roller (12).
  • the two main bearings (23) are each inserted on the main shaft (13).
  • the aerodynamic characteristics related to the path of the web (4) around the main roller (12) and the satellite roller (16) are improved.
  • the web (4) is held pressed against the main roll (12) and the satellite roll (16).
  • the voltage variations of the band (4) have been greatly reduced.
  • the design of the device (9) also makes it possible to reduce the length of free band (4) between the device (9) and the modulated introduction roller (11).
  • the main driving roller (12) may advantageously have a crown or a main gear (24) formed at one of its ends.
  • the satellite roller (16) may also have a crown or a satellite gear (26) formed at one of its ends. This satellite ring gear (26) meshes with the main ring gear (24).
  • toothed rings (24 and 26) The advantage of these toothed rings (24 and 26) is that the disturbances related to the inertia of the satellite roller (16), which accelerates and decelerates, are taken up by the driving of the main drive roller (12) and are thus not transmitted to the band (4).
  • the main electric drive motor (14) can advantageously have a pinion (27) and drive it in rotation (arrow R in Figure 3 ) via its motor shaft (28).
  • the drive shaft (28) is held by and rotates in a bearing (29).
  • This pinion (27) meshes with the main ring gear (24), which causes rotation (T) the main drive roll (12).
  • the drive of the main drive roller (12) is radially offset in a gear cascade (24 and 27) and allows the anti-torsion beam to pass through the main drive roller (12). in the form of the main shaft (13).
  • the cascade of gears (24, 26 and 27) and the motors (14 and 19) are arranged "opposite side conductive" (COC), that is to say right, relative to in the direction of travel of the strip (4), in the longitudinal direction.
  • COC opposite side conductive
  • the device (9) may very preferably further comprise a pressure roller (31), positioned against the main drive roller (12).
  • the band (4) is thus maintained further by this pressure roller (31).
