Description
- There is disclosed herein a production line for plastic bags, particularly for rolled plastic bags, where each bag produced has a radio-frequency tag.
- The need is currently felt in the art, of monitoring the origin and amount of plastic bags designed for garbage collection, and particularly plastic bags designed for separate garbage collection.
- This will allow users more committed to separate garbage collection to be rewarded, e.g. with incentives.
- For this purpose, 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.
- The information stored in the RFID tag may be used to monitor the amount and quality of the garbage collected by each user.
- In former times, radio-frequency tags were attached to plastic bags manually, which considerably increased the overall bag production times and costs.
-
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. - Then, 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.
- One of the drawbacks of the prior art is the non-negligible amount of waste caused by defective radio-frequency tags being applied to plastic bags.
- Therefore, an operation check is required on the radio-frequency tags attached to the bags, to eliminate waste; this involves an increase of production times and costs for bags with RFID tags.
- 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.
- This object is fulfilled by a production line for plastic bags as defined in claim 1.
- Further advantages may be achieved by the additional features of the dependent claims.
- A possible embodiment of the invention will be now described with reference to the accompanying drawings in which:
-
Figure 1 is a perspective view of a tagging machine, installed on a plastic bag production line; -
Figure 2 shows the same tagging machine asFigure 1 , with the addition of a roll of self-adhesive radio-frequency tags; -
Figure 3 is an enlarged view of a particular embodiment of a tagging machine, which shows how a self-adhesive radio-frequency tag is attached during bag production; and -
Figures 4a and 4b are two diagrammatic views of a production line for plastic open-mouth bags; -
Figure 5 shows a tagging machine, installed on a plastic bag production line, and an anti-static bar mounted upstream from the tagging machine; and -
Figure 6 shows a detail of the anti-static bar ofFigure 5 . - Referring to the accompanying drawings, 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 thefilm material 21 into a plurality ofbags film material 21. - A
tagging machine 8 is also provided, for attaching self-adhesive radio-frequency tags 91 to one side of thefilm material 21 that is used to form thebags Figures 1 ,2 and3 ). - In one possible embodiment, the
tagging machine 8 comprises anunwinder 82 for aweb 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. - In order to peel the self-adhesive tags, the
tagging machine 8 comprises aplate 84 that forces thebacking web 9 to make a U-turn. - The
tagging machine 8 is adapted to attach the radio-frequency tags 91 to oneside 211 of thefilm 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 theside 211 of thefilm material 21 upon which thetags 91 are attached (Figure 5 ). - Due to this feature, the waste caused by defective radio-frequency tags is reduced to negligible levels.
- While the present inventors do not intend to provide a scientific explanation for this result, they nevertheless believe that the elimination of the electrostatic charge from the
surface 211 of thefilm 21, upon which thetags 91 are later attached, avoids the risk of electrostatic charges that might destroy the microchip in the radio-frequency tags. - Usually, 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). - Furthermore, the
film material 21 may also become electrostatically charged during processing in the various workstations of the bag production line. - In the illustrated embodiment, the
means 18 for eliminating the electrostatic charge include ananti-static bar 18 extending transverse to the direction of movement of thefilm 21 and substantially parallel to thesurface 211 upon which thetags 91 are attached. - In the illustrated embodiment, the
anti-static bar 18 is located in an intermediate position between twosuccessive rollers - The distance between the
anti-static bar 18 and thesurface 211 of thefilm 21 preferably ranges from 10 to 30 mm and the supply voltage for theanti-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 thefilm 21; the generated ions neutralize excess charges on thesurface 211 of thefilm 21, thereby reducing the electrostatic voltage on thesurface 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. - As shown in
Figure 6 , theanti-static bar 18 comprises an outertubular member 181, electrically connected to ground, which hastransverse holes 182 withdischarge 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. - In an alternative embodiment (not shown), the
means 18 for eliminating the electrostatic charge are of passive type, i.e. of the type comprising grounded carbon fiber brushes. - In the illustrated embodiment, the means 2 for feeding the
films 21 include an unwinder 2 for a roll of one-ply film 21, particularly a powered unwinder. - With this solution the work speed of the production line 1 can be maximized.
- Alternatively, the machine is fed with a flat film from a roll, which is used to obtain a one-ply film.

film material 21 into a plurality ofbags ply film 21 into a succession ofbags - A pre-cutting unit 33 is provided downstream from the sealing unit 3, and pierces a series of aligned holes defining a tear-off

- In the illustrated embodiment, the
tagging machine 8 is located downstream from theantistatic bar 18 which is in turn located downstream from the sealing 3 and precutting 33 unit. - In this embodiment, the radio-
frequency tags 91 are attached to theside 211 of thefilm 21 after the formation of thebags - 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. - In an alternative embodiment, the
tagging machine 8 and theantistatic bar 18 may be located upstream from the sealing 3 and pre-cutting 33 unit, i.e. prior to conversion of thefilm 21 into joinedbags - 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. - In an alternative embodiment, not shown, 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. - This will allow adjustment of both bag size and bag throughput.
- In the illustrated embodiment, 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 anouter side 211 of thebags - 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). - In the preferred embodiment, 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 thesurface 211 of thefilm 21. - This further enhances reliability of the operation of the tagging machine.
