      2 DESCRIPTION Device for driving a sheet element for a packaging machine TECHNICAL SECTOR 5 The present invention relates to devices for driving a sheet element for packaging machines and more particularly, but not exclusively, to devices for driving laminar elements that come into contact with tubular bag material to move the tubular bag material through a forming support 10 for delivery to the packaging machine.   BACKGROUND Packaging machines receive tubular material for bags.  The product to be packaged is delivered inside the tubular bag material, then the packaging machine seals transversely and cuts the tubular bag material to form product bags.  The tubular bag material is formed by a shaper, which provides the shaping support to which the strip-shaped packaging sheet is delivered.  Conformers and packaging machines are described in US Patents 20 4910943, 5622032, 4663917, 6655110, 7159376, 7600630, 7383672, 4753336, 7124559, 7415809, 7152387 and 7472528, and in Australian Patent applications 201225840314, 20122584 20121484 , 2012201595, and 2011360138, and in International Application PCT / EP2013 / 052754.   The tubular material provided by the forming support is longitudinally sealed.  This function is carried out by heating the tubular bag material along its longitudinally overlapping edges and applying pressure to the longitudinally overlapping edges.   30 Above the shaper is a weighing machine that delivers batches of product to a sleeve that extends toward the shaper, with an inner sleeve that extends from the central shaper opening to a position adjacent or inferior to the shaper's bottom edge .   35 3 Tubular bag material passes through the shaper, is sealed longitudinally and is delivered to the packaging machine.  While this occurs, the weigher delivers batches of product into the tubular bag material, said batches consisting of product dispersed along a stretch of tubular bag material.  A device for driving a laminar element is located under the shaper and on top of the packaging machine.  The device for driving a sheet element comes into contact with the tubular bag material to cause the strip-shaped material to pass through the shaper, and delivers the tubular bag material to the packaging machine located below.  Normally, the drive unit of a laminar element includes a pair of drive belts that drive the tubular bag material at a desired speed.  The packaging machine includes at least one pair of rotationally driven jaws that have a peripheral speed (when in contact with the tubular bag material) that matches the speed of the tubular bag material as determined by the drive unit of a laminar element.   15 The product leaving the weighing machine, as mentioned above, is arranged in batches.  It is not unusual for batches to be 100 milliseconds long when leaving the weighing machine.  However, lots follow a curved path when they enter the shaper.  This causes the product to impact against itself, and against the internal surfaces of the tubular bag material.  The result is an increase in the length of product batches.  For example, the batch length can increase up to 600 milliseconds.  To ensure that the product is not placed between the packaging jaws, when programming the sealing machine, the product batches are assumed to be approximately 650 milliseconds in length.   25 The batches lengthen as the product falls through the shaper into the packaging machine.  The larger the fall distance, the greater the elongation of the lot.   A disadvantage of known packaging devices is the fact that they cannot operate at maximum speed due to undesirable lengthening of the batches.   OBJECT The object of the present invention is to solve or significantly improve at least one of the above disadvantages.   4 CHARACTERISTICS OF THE INVENTION This document discloses a device for driving a sheet element intended to come into contact with sheet-shaped material to displace the

side elevation view of a modification of the drive device shown in Figure 2; Figure 4 is a schematic, additional side elevation view of the drive device of Figure 2; Figure 5 is a schematic front

device 10 is shown schematically in the attached figures.  The device -10- includes a weighing machine -11- that includes a plurality of cuvettes -12- and -13- to which product is delivered from above, with cuvettes -12- and -13- 30 working to deliver batches of product to a hopper -14-.  The hoppers -14- deliver the batches of product to a shaper -15-.  The shaper -15- has a shaping support -41- that receives the strip-shaped bag material, and transforms the bag material strip into a tubular configuration that moves in the -16- direction.  The strip of bag material comes into contact with the outer surface of the forming support -41- to be configured in a tubular form.  Tubular bag material passes down through 13 of the opening -53- of the forming support -41-.  The direction -16- is generally vertical down.   The tubular bag material -27- comes into contact with the device for driving a sheet element -17- that draws the strip of material through the forming support 5 -41-, and delivers the tubular bag material -27- to the packaging machine -18- below.   In particular, as described in US Patent 4663917, the packaging machine -18- includes pairs of sealing jaws -31- rotated on generally parallel, but transversely separated axes, by repeated revolutions 10 in the angular directions - 33-.  Mounted with sealing jaws -31-, as described in US Patent 4663917, pairs of stretching bars -58- and closing -59- cooperate (see Figure 4).   The shaper -15- includes the shaping support -41-, as described above, and a base plate -49- of the shaper.  The forming support -41- is mounted on the base plate -49- so that it serves as a support.  It is also attached to the base plate -49- a frame -50- that fixes the duct -51- to the base plate -49-.  There is a support or heating bar -55- also attached to the base plate -49-.  Both upper rollers -21- are arranged so that they protrude at least partially 20 above the base plate -49-.   The drive device -17- includes a pair of sub-devices -19-, which are located on opposite sides of the tubular bag material -27- and both come into contact with the tubular bag material -27- to drag the tubular material to bags -27- through the device -10-.  Preferably, the sub-device -19A- is a rear sub-device and the sub-device -19B- is a front sub-device, with the sub-device -19B- coming into contact with the tubular bag material adjacent to the longitudinally overlapped edge portions of the tubular bag material .  In an alternative embodiment, the sub-devices -19-, upon contact with opposite parts of the tubular material for 30 bags, come into contact with the tubular material for bags on the sides of the tubular material for bags, that is, the sub-devices -19 - they are both separated from the longitudinally overlapped edge portions of the tubular bag material.  More particularly, the sub-devices -19- would be displaced 90º from the axis -54-.  The axis -54- is a generally vertical central axis of the packaging machine -18- and the shaper -15-.  35 14 Each sub-device -19- includes a belt -20- that passes between the first free spin roller (pulley) -21-, and the second free spin roller (pulley) -22- and a driving pulley (roller) -23 -.  The length of the belt -20- that passes between the free-spin rollers -21- and -22- provides a drive belt segment -24- that is generally linear and parallel to the direction -16-.  The segment -24- moves in the direction -16- to move the tubular material for 5 bags in the direction -16-.  The drive segment -24- is substantially vertical since the roller -21- is basically vertically above the roller -22-.   The belt -20- passes from the free spin roller -22- to the drive pulley (roller) -23- to provide a second belt segment -25-.  The belt segment -25- is generally horizontal, that is, generally perpendicular (transverse) in relation to the direction -16-.  The belt -20- passes around the pulley -23- towards the freewheel roller -21- to provide a belt segment -35-.  The pulley -23- is spaced laterally from the segment -24-.   15 The belt segment -24- follows a linear path generally parallel to the direction -16- and the extension direction of the tubular material for bags -27-.  The belt segment -25- follows a generally linear path that moves away from the tubular material for bags -27- (and segment -24-), to have an extension direction that moves away from the segment -24-.  The belt segment -35- has an extension direction that moves away from the belt segment -24-.  Preferably, segment -25- is perpendicular to segment -24-.   The belt -20- passes in the direction -26- around the free-spin rollers -21- and -22- and the drive pulley -23-.  The two belt segments -23- generally extend in parallel but are transversely spaced apart to be on opposite sides of the tubular material 25 for bags -27-.   The driving pulleys -23- are driven by a motor and control device -28- to provide the tubular material for bags -27- with a desired speed profile.  As previously mentioned, the tubular material for bags -27- moves in the direction 30-16.  However, in a further preferred embodiment, the motor and control device -28- can vary the speed in the direction -16-, and more preferably it can reverse the movement of the tubular material for bags -27-, so that by one or more short periods of time the tubular material for bags -27- is braked or even moves in a direction opposite to the direction -16-.  This movement causes the tubular material for 35 bags -27- to vibrate, helping to cause the product to settle towards the lower end of 15 the bag that is forming.  The motor and control device -28- would include a servomotor -57- or computer-controlled servomotors -57- for the pulley -23-.   The aforementioned sub-devices -19- provide a particular advantage due to the fact that the free-spin rollers -21- and -22- have a smaller diameter than that of the driving pulley 5 -23-, which allows reducing the distance between the shaper -15- and the packaging machine -18-.  This reduced length minimizes the length to which the product batches can be lengthened.  This, in turn, allows the machine -18- to operate at a higher speed, thus providing an increase in the number of bags produced per minute.  The smaller rollers -21- and -22- also provide the advantage of allowing the length 10 of the belt -20- (belt segment -24-) to be reduced, again reducing the distance between the shaper -15- and The packaging machine -18-.   Each of the belts -20- of the preferred embodiment, described above, has openings -40- that extend transversely through the belt -20-, these openings -40- communicating with a manifold -38-.  The manifolds -38- are provided with a reduced air pressure, resulting in the application of reduced air pressure to the openings -40- that extend transversely through the belt, whereby the tubular bag material is forced -27- to establish contact with the first belt segments -24-.  In particular the manifolds -38- are in communication with the openings along the first belt segment -24-.  To fix the longitudinal edge portions of the bag material by sealing (to form the tubular bag material -27-), there is a heating bar (sealer) -46-.  Preferably there is additionally a third free rotating roller -29- which is mounted on an articulated movable arm -30- so that the roller -29- is forced to contact the belt -20- which in turn forces the belt - 20- to contact the drive pulley -23-.   Preferably, the free-rotating rollers -21- and -22- have generally parallel rotation axes arranged transversely in relation to the direction -16-, while the rollers -21- and -22- have axes that are generally parallel to the rotation axes of the 30 drive pulleys -23-.   In the embodiment of Figures 1, 2, 4, 5 and 6, the upper roller -21A- protrudes at least partially above the lower edge part -42- of the forming support -41-, and is at least partially located in the cavity -52-.  This has the particular advantage of 35 16 reduce the distance between the shaper -41- and the packaging machine -18-, minimizing the lengthening of the lots.   In the embodiment of figures 1, 2, 4, 5 and 6, the upper roller -21B- protrudes at least partially above the base plate -49-.  This provides the particular advantage of reducing the distance between the forming support -41- and the packaging machine -18-.  By minimizing this distance, the elongation of the lots is also minimized.  In addition to this, an additional advantage is achieved by placing the upper roller -21A- at least partially above the base plate -49-, again allowing the distance between the forming support -41- and the packaging machine -18- be reduced.  In the embodiment of Figures 3 and 4, the upper rollers -21- have an increased size and do not protrude above the lower edge portion -42-.  However, it should be borne in mind that with respect to the embodiments of Figures 3 and 4, the upper rollers -21- could have a reduced size and be moved up to be located at least partially in the recess -45- that provides the forming support -41-, which protrudes at least partially above the lower edge portion -42-.   Each jaw -31- is mounted on an axis -32- by means of jaw supports (arms) -47-, with the axes -32- driven in rotation in opposite angular directions 20 -33-.  In the same way, the sealing jaws -31- are operated in synchrony by repeated revolutions around generally parallel axes, the axes being generally transverse to the direction -16-.  The sealing jaws -31- come into contact with the tubular bag material -27-, transversely seal the bag material -27-, and cut the bag material -27- to form separate bags.  25 The axes -32- are driven by the motor and control device -34-, which works to make the axles -32- have a desired angular velocity profile.  Preferably, the motor and control device -34- operates so that the jaws -31- have a peripheral speed, when one is adjacent to the other to come into contact with the tubular bag material -27-, which is smaller that the speed of the tubular material for bags -27- on the straps -24-.  In a further preferred embodiment, the jaws -31- when adjacent to each other, to come into contact with the tubular bag material -27-, can for one or more short periods of time turn upside down to move in one direction. opposite to the direction of rotation -33-.  This operation of the sealing jaws 35 helps to cause the product to settle towards the lower end of 17 the bag that is forming.  By forcing the product towards the lower end of the bag being formed, the probability that the sealing jaws -31- grab the product is reduced.  This also helps increase the rate of bag production.  However, when the jaws -31- come into contact with the bag material -27- to form a seal therein, the jaws -31- have the same speed as the material for 5 bags -27- between the jaws -31 -.  Similarly, the material for bags -27-, when moving with the jaws -31-, changes speed.   The motor and control device -34- would include a computer and a servomotor or servomotors -57- for the axis -32-, where the computer is programmed to operate the servomotor or servomotors -57- to produce the desired speed profile .   In the embodiment of Figure 4, each of the sub-devices -19- includes only the drive pulley -23- and one of the free spinning rollers (pulleys) -21-.  The belts -20- pass around the pulleys -23- and the free-spin rollers -21- in the direction -26-.  As described above, the driving pulleys -23- would be driven by the motor and control device -28- to provide a desired speed profile to the belts -20-.  For example, the belts -20- can be braked and / or operated in reverse as discussed in the previous embodiment.   20 The motor and control device -28-, and the motor and control device -34-, can share a computer that controls the operation of the servomotors -57- that drive the motor pulleys -23- and the axles -32- , so that the sealing jaws -31- are coordinated with the speed of the tubular material for bags -27-.  However, it should also be borne in mind that the computer could control the servomotors so that the sealing jaws -31- have a peripheral speed, when they are adjacent or in contact with the tubular bag material -27-, which it is different than the speed provided to the tubular material for bags -27- by the belt -20-.  For example, the jaws -31-, and the bag material -27- in contact with them, may have a lower speed causing the product to settle at the lower end of the bag, with the jaws -31- increasing by speed when transverse sealing is going to be done on the bag.  In another embodiment, the jaws -31- can have a speed opposite to the direction of movement of the tubular bag material -27- when the jaws -31- are adjacent to the material -27-.   35 18 The above embodiments have the advantage of forcing the product towards the lower end of the bag being formed.  This is achieved by changing the speed of the bag material -27-.  This change in speed that makes the bag material vibrate -27- allows the bags to be produced more quickly.
