Definitions

  • the present invention relates to a preferred device for the advantage of a film web in a bag filling plant, a bag filling plant with such a preferred device and a method for setting a tension of a film web in a bag filling plant.
  • Bag filling systems and preferred devices for bag filling systems are known in principle.
  • bag filling plants are used for filling sacks or bag sections of a film web with bulk material. This is often starting from a continuous film web, z.
  • a promotion performed by the bag filling It must be ensured that a transport force for the promotion to the Film web is transmitted.
  • preference is usually provided in the form of preferred drives.
  • a main feed roller is provided, which transmits by appropriate contact pressure on the film web and corresponding frictional engagement or frictional contact a transport force for the benefit of the film web on the same. This results in that the film web can be promoted by this power transmission through the bag filling system.
  • a disadvantage of known bag filling systems is that usually a buffer device must be provided in order to switch from a continuous rolling of a Medicarerolle in a clocked or batch-wise conveying to the individual filling stations of the bag filling system.
  • a buffer device is usually designed as a dancer.
  • this dancer device is in a pendulum mode, this leads to the fact that after completion of a conveyor cycle in the clocked area of the bag filling an undesired Roth circuitn for a short period of time for the film web. This further conveying, although the current film web end has already been stopped, leads to a reduction of the tensile stress in the film web.
  • the film web will be looser in the bag filling line in the area up to its end.
  • a sufficient tension is necessary. Accordingly, it must wait in known bag filling after stopping a delivery cycle until the pendulum movement of the buffer device has been carried out again in the other direction of movement so far that the desired tension has been reached again.
  • a preferred device according to the invention is designed for the advantage of a film web in a bag filling system.
  • the preferred device has a main advancing drive with at least one driven main feed roller for the advantage of the film web.
  • a preferred device according to the invention is characterized in that for adjusting the tension of the film web in the transport direction of the film web in front of the main advancing drive an auxiliary advancing drive is arranged with at least one driven auxiliary advancing roller for the benefit of the film web.
  • a preferred device is characterized by two separate preferred drives, namely the main advancing drive and the auxiliary advancing drive. These are arranged in a decisive manner locally spaced apart. Over the course of the film web along the conveying direction in the bag filling system so first the auxiliary advancing drive and only later the main advancing drive is arranged.
  • the main advancing drive is located at a position within the bag filling system at which a cutting and cutting into individual bag sections takes place.
  • the auxiliary advancing drive is preferably provided in the vicinity of the dancer device, ie in particular directly after the dancer device or the buffer device.
  • the auxiliary advancing drive is arranged upstream of the main advancing drive and at the same time downstream of the buffer device.
  • an overshoot or forwarding after the stop of the main advancing drive is preferably avoidable.
  • the auxiliary advancing drive can serve, so to speak, as a stopper for the film web to penetrate into the region between the two preferred drives in a swinging manner.
  • a different preferred speed for the two preferred drives can be adjusted by different regulations.
  • a preferred drive are basically a main feed roller and a corresponding drive device, eg. As an electric motor to understand.
  • a common drive device can be provided for both preferred drives.
  • each preferred drive it is also possible for each preferred drive to have its own drive device which can be controlled separately.
  • the two preferred drives are preferably coupled to each other such that a speed difference or an exact speed correlation in the drive of the two feed rollers of the main advancing drive and the auxiliary advancing drive is adjustable.
  • a preferred apparatus according to the invention is used in particular for a bag filling plant according to the so-called FFS (Form-Fill-Seal) method.
  • FFS Form-Fill-Seal
  • a bag filling system is based on a NASArolle, which provides a film web, in particular a tubular film, substantially in an endless structure available. This film web extends into the bag filling system and is continuously conveyed away from the preliminary roller.
  • a buffer device which can be designed as a dancer device, converts the continuous conveying mode into a cyclic feed. Following this buffer device, the auxiliary advancing drive is preferably already arranged.
  • sealing devices for corner welds and corresponding cooling devices can be provided, so that finally a bottom sealing station for the production of a bottom seam and the cutting to length into individual bag sections can be provided on the continuous extension of the film web.
  • a further transport of the bag sections to a filling station as well as to a top seam station and a cooling station for the cooling of the top seam take place.
  • the transfer of the transport force from the respective feed roller to the film web is preferably carried out via a frictional contact or a frictional engagement between the respective feed roller and the film web.
  • This frictional engagement is enhanced by corresponding wrap angles, which are preferably in the range of about 180 ° or more.
  • a plurality of feed rollers may be provided, wherein one or more of these feed rollers are drivable.
  • a driven film roll and a freely rotatable feed roll are provided, between which forms a conveying gap for the promotion of the film web.
  • wrap angles of more than 180 ° can be achieved.
  • the two preferred drives are preferably temporal synchronous drives, which can be synchronized to the cycle of the machine.
  • both preferred drives are preferably at the same time periods in operation and at the same time periods at a standstill. If the main advancing roller of the main advancing drive stops, the auxiliary advancing roller auxiliary advancing roller stops correspondingly.
  • the auxiliary advancing drive thus forms a safeguard, so that further conveyance is avoided by not yet swinging back the pendulum of the buffer device for the film web in the section between the two preferred drives.
  • the stations of processing for the film web which are the subordinate auxiliary drive downstream in the transport direction, can therefore be carried out immediately, so no more waiting time has to be awaited.
  • the machine cycle can be accelerated and thus a higher production capacity of the bag filling system can be achieved.
  • the main advancing drive has a different preferred speed than the auxiliary advancing drive, in particular having a higher preferred speed than the auxiliary advancing drive, is operable.
  • a lead is set relative to the auxiliary advancing drive or for the auxiliary advancing drive a so-called lag relative to the main advancing drive for the main advancing drive.
  • the main preferred drive promotes the film web accordingly faster than the auxiliary advancing drive.
  • the conveying distance between the main advancing drive and the auxiliary advancing drive is constant, a defined tension in the film web is maintained by the conveying speed difference of the two preferred drives.
  • the setting of the different preferred speeds can be done in different ways. For example, an electronic coupling can be provided, which drives at different drive devices of the two preferred drives with separate and different preferred speeds. Other coupling forms, z. As mechanical coupling devices are conceivable within the scope of the present invention and will be explained later in more detail.
  • the preferred speed is that speed which is preferably formed by the rotational speed of the respective feed roller. A difference accordingly leads to different transport speeds of the film web on the respective feed roller.
  • the main advancing drive is coupled with the auxiliary advancing drive at least partially via a mechanical coupling device which predetermines the correlation of the preferred speeds of the two drives via a transmission.
  • transmission is here to be understood widely, so that already the correlation of a belt drive with two pulleys, each one pulley is arranged on a preferred drive, is to be understood as a transmission.
  • the transmission according to the invention fulfills the function of a translation or a reduction in order to be able to consciously ensure a speed correlation, in particular a speed difference between the two preferred drives.
  • more complex gear especially with gears or sprockets in the context of the present invention conceivable.
  • a major advantage of the mechanical coupling device is the automatic synchronization of the two preferred drives to each other.
  • a common drive device available, so that here too costs and complexity can be saved.

  • an electronic coupling device can, for. B. be provided by a control device of a bag filling available. So z.
  • the main prime mover is provided with a main prime mover, while the auxiliary prime mover has an auxiliary prime mover.
  • the respective drive device applies a rotational force to the respective feed roller so that a corresponding preferred speed for the respective preferred drive is established.
  • This rotational speed is preferably controlled or regulated by a common control device, so that an explicit correlation of the respective rotational speed to one another and thus a defined correlation of the preferred speeds of the two drives can be set.
  • a change in the correlation is possible in this way particularly simple and especially during operation.
  • the main advantage is preferably connected as a master, while the auxiliary advantage is aligned with its drive as a slave to the master. So z. B. a defined lag for the generation of a desired Buchschreibshongs be set on the film web, so that only the main preferred drive is controlled in a direct manner.
  • the slave circuit follows the Hilfsvorzugsantrieb with a set and defined lag automatically as lag value the main preferred drive.
  • main advancing drive and the auxiliary advancing drive are correlated with one another on a common clock, in particular synchronously in a common clock, are operable. This means that a correlation takes place in particular on the machine cycle.
  • main prime drive and auxiliary advancement drive are thus started to operate at the same time and stopped again at the same time.
  • a complete synchronized operation of the two preferred drives By selecting a mechanical coupling, as has been explained, this synchronization is generated almost automatically.
  • the main advancing drive and / or the auxiliary advancing drive have at least one freely rotatable film roller.
  • This may have in correlation to the driven feed roller with this the common conveying gap for the implementation and thus the transport of the film web.
  • the defined conveying gap thus leads in particular to a sufficient contact pressure of the driven feed roller on the film web.
