Definitions

  • plastic bags are known to receive a radio-frequency tag (known as RFID tag) attached thereto, which may contain information, such as: bag's weight, bag's origin, user's personal details, user's health insurance card data, etc.
  • RFID tag radio-frequency tag
  • the information stored in the RFID tag may be used to monitor the amount and quality of the garbage collected by each user.
  • CN 101 462 603 discloses a production line for plastic bags manufactured from a flat moving film, which is fed beneath a tagging machine, which intermittently attaches tags.
  • the film is folded into a one-ply film.
  • Sealing and cutting mans are further provided for converting the one-ply film into bags, with a radio-frequency tag attached to the inner side of the bags.
  • the object of this invention is to obviate at least some of prior art problems and particularly to reduce the waste caused by faulty radio-frequency tags.
  • numeral 1 generally designates a plastic bag production line, particularly for polyethylene open-mouth bags with string closure.
  • the production line 1 comprises means 2 for feeding a film material 21 and means 3, 33 for converting the film material 21 into a plurality of bags 4, 4, ... 4, with walls formed of the film material 21.
  • a tagging machine 8 is also provided, for attaching self-adhesive radio-frequency tags 91 to one side of the film material 21 that is used to form the bags 4, 4, ... 4 (see Figures 1 , 2 and 3 ).
  • the tagging machine 8 comprises an unwinder 82 for a web roll 9 which acts as a backing material for the self-adhesive tags 91.
  • the web 9 is fed by a drive shaft 83 with a stepper motor.
  • the tagging machine 8 comprises a plate 84 that forces the backing web 9 to make a U-turn.
  • the tagging machine 8 is adapted to attach the radio-frequency tags 91 to one side 211 of the film material 21.
  • One feature of the bag production line is that it has means 18 located upstream from the tagging machine 8, for eliminating static electricity from the side 211 of the film material 21 upon which the tags 91 are attached ( Figure 5 ).
  • the electrostatic charge to be eliminated is already on the roll of the film material 21 that is used for bag production (e.g. due to the mechanical processing required to form the reel itself, such as: stretching, compression and rubbing).
  • the film material 21 may also become electrostatically charged during processing in the various workstations of the bag production line.
  • the means 18 for eliminating the electrostatic charge include an anti-static bar 18 extending transverse to the direction of movement of the film 21 and substantially parallel to the surface 211 upon which the tags 91 are attached.
  • the anti-static bar 18 is located in an intermediate position between two successive rollers 11, 12.
  • the distance between the anti-static bar 18 and the surface 211 of the film 21 preferably ranges from 10 to 30 mm and the supply voltage for the anti-static bar 18 is preferably at least 5000 Volt.
  • the power supply polarity of the anti-static bar depends on the film material being used.
  • the anti-static bar creates an ionized air zone between the bar and the surface 211 of the film 21; the generated ions neutralize excess charges on the surface 211 of the film 21, thereby reducing the electrostatic voltage on the surface 211 of the film to a value close to zero Volt, or anyway to a voltage value low enough to avoid damages to the radio-frequency tags.
  • the anti-static bar 18 comprises an outer tubular member 181, electrically connected to ground, which has transverse holes 182 with discharge points 183 held therein, and capacitively coupled to the power source.
  • the anti-static bar 18 may be of traditional type, and will not be further described herein.
  • the means 18 for eliminating the electrostatic charge are of passive type, i.e. of the type comprising grounded carbon fiber brushes.
  • the means 2 for feeding the films 21 include an unwinder 2 for a roll of one-ply film 21, particularly a powered unwinder.
  • the machine is fed with a flat film from a roll, which is used to obtain a one-ply film.
  • the means 3, 33 for converting the film material 21 into a plurality of bags 4, 4, ... 4 include a sealing unit 3, which divides the one-ply film 21 into a succession of bags 4, 4, ... 4. joined by transverse sealing lines.
  • a pre-cutting unit 33 is provided downstream from the sealing unit 3, and pierces a series of aligned holes defining a tear-off line 41 transverse to the direction of movement of the one-ply film 21, proximate to each sealing line.
  • the sealing and pre-cutting unit 3 comprises actuator means (not shown), e.g. brushless motors, for moving the sealing and pre-cutting unit 3, 33 up and down.
  • actuator means e.g. brushless motors
  • the sealing and pre-cutting unit 3, 33 may be of traditional type, and will not be further described herein.
  • the tagging machine 8 is located downstream from the antistatic bar 18 which is in turn located downstream from the sealing 3 and precutting 33 unit.
  • the radio-frequency tags 91 are attached to the side 211 of the film 21 after the formation of the bags 4, 4, ..., 4.
  • the position of the tagging machine 8 downstream from the sealing 3 and precutting 33 unit has certain advantages: particularly, it minimizes the mechanical stresses acting on radio-frequency tags during bag production.
  • the tagging machine 8 and the antistatic bar 18 may be located upstream from the sealing 3 and pre-cutting 33 unit, i.e. prior to conversion of the film 21 into joined bags 4, 4, 4..., 4.
  • the plastic bag production line may include a dandy roll unit 6, which is located downstream from the sealing 3 and pre-cutting 33 unit, as well as a winder 7 which is in turn located downstream from the dandy roll unit 6, to create rolls of successive bags, joined by pre-cut lines.
  • the dandy rolls 6 hold the bags 4 under tension during the time from the end of the formation of a roll of bags to the start of the formation of the next roll.
  • the bags may be manufactured in loose form.
  • the speed at which the one-ply film 21 is fed and the rate at which the sealing and pre-cutting unit is lowered may be adjusted as needed, by console control.
  • the tagging machine 8 is located downstream from the sealing unit 3 and the pre-cutting unit 33 and upstream from the dandy roll unit 6, and the radio-frequency tags 91 are attached to an outer side 211 of the bags 4, 4, ... 4 while they are being fed.
  • the tagging machine 8 is synchronized with the sealing 3 and pre-cutting 33 unit, thereby ensuring the proper pitch of the tags 9 on the bags 4.
  • the synchronization of the tagging machine 8 with the sealing unit 3 (and pre-cutting unit 33) is controlled by a relay (not shown), which is in turn controlled by an electric signal which is synchronized (in phase) with the signal that controls the descent of the sealing unit 3 (and precutting unit 33).
  • the pulse that controls the tagging machine 8 comes from a PLC (not shown).
  • the tagging machine 8 is equipped with an optical sensor which is adapted to read the pitch and number of self-adhesive radio-frequency tags 9, which are attached to the surface 211 of the film 21.
  • an idle roller 81 having an axis of rotation substantially parallel to the surface 211 is added, where the radio-frequency tags 91 are peeled off the backing web 9.
  • the idle roller 81 is adapted to apply pressure to the radio-frequency tags 91, as they are peeled off the backing web 9, thereby ensuring proper positioning of the tags 91 on each bag 4, 4, ... 4 and preventing the tags 91 from being blown off during peeling.
  • the idle roller 81 affords a further increase of the throughput of the equipment, by maximizing production without the risk that the radio-frequency tags (RFID tags) 91 might be blown off or be inaccurately attached.
  • RFID tags radio-frequency tags
  • the above arrangements allow operation with a throughput of about 4 bags/second, corresponding to a linear speed of about 2.4 meters/second.
  • the idle roller 81 applies pressure to the tags 91 with its own weight; for this purpose, the idle roller 81 is fixed to an arm 811 which is hinged to the tagging machine 8.
  • the idle roller 81 is a roller made of synthetic sponge or foam rubber.
  • the bag production line produces bag rolls.
  • the invention may be also used in production lines for loose bags.
  • the radio-frequency tag is placed on the exterior of the bag.
  • the material that forms the bags and the conformation of the bags being produced may change as needed, and no limitation is imposed thereto.
  • the invention may be also used in production lines for handled bags, shoppers, die-cut handle bags, bags made of biodegradable materials, etc.
