Definitions
- the present invention relates to the field of the manufacture of packaging bags. More specifically, the present invention relates to devices for manufacturing packaging bags by continuous movement of a film fitted with at least one strip with an opening / closing function. Even more precisely, the present invention preferably applies to devices for manufacturing bags in which the strip with opening / closing function is arranged transversely to the direction of travel of the film.
- the present invention is not limited to this specific application.
- the invention can also be applied to devices in which said strips with an opening / closing function are arranged parallel to the direction of travel of the film or at an angle to this direction.
- the opening / closing strip can take many forms.
- the strip with an opening / closing function can be formed of complementary closing profiles, for example male / female profiles, or with complementary hooks, arranged on opposite faces of the film.
- the strip with an opening / closing function can also be formed from a profile or a tear-out / cutting strip, from an adhesive strip, peelable or not, or also from a metal strip for closing by folding, etc ...
- Such devices for manufacturing packaging bags with horizontal or vertical scrolling are known.
- machines known as FFS are known for the English expression “Form, Fill and Seal”, that is to say a machine designed for forming bags, filling and then closing them automatically.
- FFS machines are known in particular comprising: means of conveying a film in the planar state,
- these latter means are generally designed to ensure almost simultaneously a weld constituting for example the bottom of an upstream bag in the direction of travel, a second weld at the mouth of a downstream bag, and a sectioning of tubular film to isolate the finished downstream bag from the upstream bag during preparation.
- machines are known today comprising a station designed for fixing the strip with an opening / closing function, on the film, upstream of the forming neck, transversely with respect to the direction of movement of the film.
- the closure strip can be deposited longitudinally, that is to say parallel to the direction of movement of the film, or obliquely with respect to this direction.
- the present invention now aims to improve the known packaging bag manufacturing devices by allowing reliable detection of the positioning of the strip with opening / closing function.
- This object is achieved in the context of the present invention, thanks to a bag-forming device comprising at least one sensor capable of detecting the presence of a strip with an open / close function, in a predetermined relative position relative to the cyclic film processing means for the formation of the sachet, in particular with respect to the transverse fixing means of the film making up the sachet, provided on the device.
- the senor consists of a mechanical probe.
- the present invention also relates to a method for forming sachets.
- FIG. 1 represents a schematic view of a device for forming packaging bags in accordance with the present invention
- FIGS. 2 and 3 show views on an enlarged scale of a sensor according to the present invention, respectively in the case of a detection of correct positioning of a strip and in the case of an incorrect position detection of that -this,
- FIG. 4 represents a partial side view of the device illustrating the location of the sensor
- Figures 5, 6, 7 and 8 show two views similar to Figures 2 and 3, in the case of a double sensor and respectively on the assumption of correct positioning detection for Figure 5 and incorrect positioning for Figures 6, 7 and 8 of the strip in question.
- the description which follows will relate essentially to a device in which the closure / opening strip is arranged transversely to the direction of movement of the film.
- the invention is not limited to this provision.
- the invention also applies to devices in which the strip of closing / opening is placed parallel or oblique to the direction of movement of the film.
- FIG 1 a device for forming packaging bags to which particularly applies, but is not limited to, the invention.
- This is a FFS type machine with vertical scrolling.
- the film 12 is guided using different rollers or equivalent means which will not be described in detail below, insofar as they can be the subject of numerous variant embodiments.
- the device comprises downstream of the roller 10 a station 14 at which a strip with an opening / closing function is deposited on the film 12 transversely to the direction of movement of this film.
- the film 12 then reaches a forming neck 16.
- the latter is shaped so that at the exit from the forming neck 16, the film 12 is in the tubular state.
- a filling chute 18 superimposed on the forming neck 16 opens into the tube thus formed.
- the filling chute 18 is used to introduce the product to be packaged into the blanks of sachets formed by the above-mentioned tubular film.
- Means shown diagrammatically in FIG. 1 under the reference 20 are designed to ensure the longitudinal closing of the tubular film, for example by thermal welding. Downstream of this station 20, there is an assembly 30 designed to ensure:
- sectioning means 36 inserted between the aforementioned means 32 and 34, a sectioning of the film to separate the finished downstream bag from the upstream bag blank, and - Optionally using means 38, the finishing of the fixing of the strip with opening / closing function on the wall of the film.
- the strip with opening / closing function can be fixed, at the level of the station 14, only over half the width of the film, the fixing on the other half of the width of the film being carried out. downstream of the forming neck 16, using the aforementioned means 38.
- the machine illustrated in FIG. 1 is a vertical scrolling machine.
- the present invention also applies to machines with horizontal scrolling.
- the present invention can also find application in bag-forming devices using a film 12 pre-provided with strips with a transverse opening / closing function at the level of the reel 10.
- the invention applies to pouch forming devices in which the strip with closing opening function is attached to the film 12 at a location different from that illustrated in FIG. 1, for example at the level of the forming neck 16 or downstream thereof.
- the present invention applies to any type of band with the function of opening / closing of sachets, in particular the bands comprising complementary closure profiles, such as male / female or with complementary hooks, tear / cut tapes, adhesive tapes, peelable or not, metal strips for closing by folding, etc.
- the strip with opening / closing function has the general reference 60.
- the present invention applies to any type of film 12, such as for example plastic films, simple or composite, metallized films, etc.
- the sensor 100 consists of a mechanical feeler comprising a pusher 102 biased towards the film 12, which is sandwiched between the feeler or pusher 102 and a stop 110 forming an anvil.
- the pusher 102 is associated with an electrical contactor 104 sensitive to the position of the pusher 102, that is to say closed or open, depending on whether the closing / opening strip 60 is present or not and whether or not forms an additional thickness between the stop 110 and pusher 102.
- the senor 100 is placed downstream of the jaws 100 ensuring the transverse welding of the film.
- the sensor 100 and the anvil 110 are carried by the jaw support unit 30 so that the anvil 110 and the sensor 100 are cyclically distant and brought closer to the film 12 in synchronism with the jaws of welding 30 so as not to disturb the movement of the film 12.
- the sensor 100 is located at the longitudinal edge of the sachet opposite to that by which the strip with opening / closing function 60 is conveyed.
- FIG. 4 shows diagrammatically under the arrow referenced A the routing of this strip 60.
- the sensor 100 makes it possible to detect both: - the presence of the strip 60 with an open / close function, - the correct routing in the transverse direction, of the strip 60, that is to say the verification of the coverage of the film by the strip 60 (in the event of a defect, the strip 60 does not cover the entire mouth of the sachet, we can expect a failure to subsequently close, or even a leak), and - the correct positioning of the strip 60 in the longitudinal direction relative to the direction of travel of the film (a positioning fault in this direction would lead to a positioning fault of the strip with opening / closing function relative to the mouth of the bag).
- FIG. 2 thus illustrates the case of correct positioning of the strip 60 relative to the welding jaws 30.
- FIG. 3 illustrates the case of detection of incorrect position of the strip. 60 (in this case, the strip 60 is situated too far in front of the running of the film).
- the present invention thus makes it possible to eliminate drifts due in particular to the intrinsic elasticity of the film 12, to see deformations of the latter due to its quality, or even, depending on the type of products packaged or the way in which the product is poured into the sachets through the chute 18.
- the present invention also applies to devices in which the opening / closing strip is arranged not transversely, but longitudinally, that is to say parallel to the direction of displacement of the film or even obliquely with respect to this direction (it suffices to adapt the position of the sensors).
- at least two sensors can be provided respectively near each edge of the bag, according to an oblique generatrix with respect to the direction of movement of the film, corresponding to the expected oblique position of the strip.
- the present invention is not limited to the particular embodiments which have just been described, but extends to all variants in accordance with its spirit.
