Definitions

the present invention refers to a vertical bagging machine, intended for packaging with bags provided with strengthening and lateral shaping edges and square bottoms (sometimes also called “stabilo" bags).
“Stabilo” bags are bags provided with four vertical sealed folds to form four lateral edges; the presence of the edges gives the bag a shape that is similar to that of a parallelepipedon that is able to be free-standing by resting on its rectangular base.
the general object of this invention is to overcome the drawbacks mentioned above by providing a bagging machine for packaging with "stabilo" bags that enables high bagging speed and a satisfactory productivity level to be achieved.
a further object is to make a bagging machine that is reliable and has a simple and economical structure.
a vertical bagging machine for forming bags in plastic film comprising a pipe with a substantially circular and oval cross-section for delivering the product around which are formed and guided from top to bottom a pipe of plastic film and transverse sealing means of the pipe of film arranged downstream of the bottom end of the delivery pipe for forming a sequence of closed bags containing the delivered product, characterised in that along the delivery pipe there is means for the formation of longitudinal folds along the pipe of film and sealing means of said folds, guide means being arranged at the bottom end of the delivery pipe to give the pipe of film a rectangular section with said folds at corners of the rectangular section.
figure 1 shows a vertical bagging machine 11 for the formation of bags equipped with four sealed side folds for making lateral stabilisation edges; these bags, an example of which is shown in the example in figure 4, are known in the packaging field as "stabilo" bags.
the bagging machine 11 comprises a delivery pipe 12 (which may be vertical or be arranged according to a desired tilt) around which a pipe of continuous plastic film is guided from top to bottom.
the pipe of film is formed around the delivery pipe 12 by appropriate means 14 starting from a web of continuous film that is supplied to the machine (not shown in the figure).
the means 14 comprises a guide profile arranged near the top end of the delivery pipe 12 and is made according to techniques known in the field of bagging with vertical machines; the means will therefore not be disclosed with further details.
the delivery pipe 12 has a top opening upstream of which there is arranged known means of dosing the product to be packaged (not shown in the figure).
the pipe of film that forms around the delivery pipe 12 runs from top to bottom, dragged by known movement means (not shown). Dragging is indexed, to enable closing sealing of a bag at each advance step of the pipe of film downwards.
the pipe 12 is fixed to a support structure 13 on which the means 14 is also mounted for winding the film around the delivery pipe 12.
Figure 2 shows the bagging machine according to the invention with some parts removed. Note, at the height of the profile 14 for winding the web of film, the folding means 29, 30 and 31, which have the function of forming two longitudinal folds which extend to the outside in the pipe of film wrapped around the delivery pipe 12.
the two vertical ribs 31 are fixed to the delivery pipe 12 and are intended to stay inside the pipe of film (not shown) during operation of the machine.
the two flaps 30, are fixed to the support structure 13, just like the guide body 29.
the guide body 29 is arranged between the two ribs 31, whereas the flaps 30 are positioned to the side of the ribs 31, parallel to them.
the flaps 30 and the guide 29 remain outside the pipe of film and with the ribs 31 define two thin gaps that are suitable for forming two folds protruding outside the pipe of film.
folding means 60, 61 On the opposite side of the delivery pipe very similar folding means 60, 61 is arranged, which forms two folds that mirror the two formed by the means 29, 30 and 31.
the pipe of film assumes a cross-section that is similar to the one shown in figure 6, with the folds 51 protruding parallel to one another towards the outside from the pipe of film with a circular section.
the ribs 31, in an embodiment of the invention protrude parallel to one another from the delivery pipe.
sealing unit 41 is arranged, that is intended to seal the two folds formed by the corresponding folding means.
the sealing unit 41 is supported by an arm 20 fixed to the support structure 13 and comprises a pair of vertical sealing blades 22, moved hydraulically or pneumatically by known drive means 25.
the two blades 22 are suitable for closing in the direction of the contrast body 23 to pinch the longitudinal folds formed upstream of the corresponding folding means at each advance step of the film downwards.
the blades 22 and the contrast body 23 are arranged vertically and have an elongated shape, in particular, their length must be at least the same as the height of a bag, to ensure the formation of the side edges along the entire extent of the pipe of film.
the second sealing unit 42 On the side diametrically opposite the delivery pipe 12 the second sealing unit 42 is arranged, which is completely similar to the sealing unit 41 and is intended to operate on the longitudinal folds formed by the folding means 60, 61.
the machine could also comprise further longitudinal sealing means, intended to close longitudinally the pipe of film wound around the delivery pipe 12. Normally however, the longitudinal closure of the pipe occurs at one of the four seams of the folds 51, avoiding a further fifth seam being made on the pipe of film.
the delivery port 15 is made from which the product to be packaged emerges (see figure 1).
the delivery pipe 12 is shaped with a virtually circular cross-section along its entire extent as far as the delivery port 15.
the pipe section could be oval or have similar shapes (without sharp corners).
the means 16 Downstream of the delivery port 15 there is arranged means 16 to give the pipe of film a virtually rectangular cross-section.
the means 16 comprises a pair of guides 16 that push on the walls of the film from the inside of the pipe, gradually deviating the rectangular cross-section from the circular shape to the rectangular shape.
the two guides 16 extend from the port 15 downwards and have an angular position in relation to the folding means such that the sealed longitudinal folds are at the top of the rectangular section of the pipe of film.
Figure 5 shows the section that the pipe of film assumes downstream of the guides 16, with the sealed folds 51 at the tops of the rectangle described by the pipe.
the terminal part of the guides (or walls) 16 defines the short side of the rectangle described by the rectangular cross-section of the pipe of film. This solution enables it to be prevented that the walls 16 interfere in some way with the delivery flow, as they broaden out slightly as they move further away from the axis of the delivery pipe.
transverse sealing means 27 At a lower height in relation to the guides 16 known transverse sealing means 27 is arranged (shown schematically in figure 1), possibly equipped with known means for shaping (for example square) of the bottom of the bag.
the transverse sealing means 27 At each advance step of the pipe of film, the transverse sealing means 27 carries out a closing seal of the bags to form a sequence of bags starting with the continuous pipe of film. Sealing is performed parallel to two walls of the pipe of film, in such a way as to make a bag with a shape similar to that of a parallelepipedon.
transverse sealing means 27 means can be arranged to cut the bag that has just been formed from the pipe of film.
a bagging machine has been made for the formation of "stabilo"-type bags that is able to reach high packaging speeds and high productivity.
the circular section of the delivery pipe enables the time to be minimised for delivering product with the same bag dimension, thereby speeding up the total bagging process.
the machine according to the invention enables the frequency of jams and blockages to be reduced, contributing to increasing further the productivity of the machine.
