Definitions

• the present invention concerns a unit for the packaging of bags, sachets, sticks, flowpacks and the like in box-shaped cases.
• the present invention relates to a unit for packaging bags, sachets, sticks, flowpacks and the like, e.g. containing pharmaceutical, cosmetic, food, chemical, and other products, supplied in granular, powder, liquid, viscous or solid form, in tablets, and the like, in box-shaped cases, the latter being, for example, in the shape of a parallelepiped but also other shapes.
• sachets means, for convenience, bags, sachets, sticks, flowpacks, or the like.
• sachets are in turn packaged for sale in cases, for example of cardboard or other suitable material, by packaging machines of a known kind.
• cases are box-like and have substantially a parallelepiped shape, or even different shapes.
• the sachets to be packaged are fed in a predetermined number to one or more respective inserting stations, which are generally movable along a predetermined feeding path.
• cartons are initially contained in a store in which they are, for example, in a flattened configuration, or they are stored directly in the form of semi-finished blanks.
• Each case is taken from the store, formed and/or opened by respective opening means, and conveyed with an open side to a respective inserting station, at which the sachets are inserted into the case by means of inserting means.
• each case rests on one side parallel to the ground, and has one open side facing the station, through which the sachets are let in.
• the sachets which have an irregular shape, or in any case a shape not suitable for their stacking one on top of the other, can accidentally slip one with respect to the other, especially if the case has not been completely filled yet: this can cause incorrect packaging of the sachets, or damage to the sachets and/or the cases, or even - if the sachets accidentally come out of the case - jamming of the machine, with subsequent downtime and service costs.
• the here above described phenomenon can be further amplified by the fact that often, the sachets will contain powdery or granular material which is free to move, and consequently, change in an unpredictable manner the position of the centre of gravity of the sachet itself.
• the aim of the present invention is to improve the state of the art.
• one object of the present invention is to develop a packaging unit that allows for the correct insertion of sachets and the like into respective box-shaped cases, preventing their incorrect positioning inside the case itself and/or accidental sliding out.
• Another object of the present invention is to make a packaging unit available which allows the aforementioned purposes to be achieved via a technical solution characterised by low costs and by a simple and effective use.
• the packaging unit comprises support means for at least one box-shaped case open at one side and resting on one flank, and a station for inserting one or more sachets, or the like, inside the case itself.
• the inserting station comprises inserting means suitable for pushing one or more sachets, or the like, onwards into the inside of the case through the aforementioned open side.
• the supporting means comprise positioning members of the case in a configuration in which the supporting flank is inclined to a predetermined angle with respect to a horizontal plane.

• sachets 4 shall mean, for convenience, bags, sachets, sticks, flowpacks, or the like: therefore the list of possible types of container will not be repeated each time, in order not to weigh down the reading.
• the unit 1 further comprises an inserting station 5 of one or more sachets 4 into the case 3.
• the inserting station 5 comprises inserting means 6.
• the inserting station 5 can comprise, for example, a collection portion 5a of the sachets 4 to be inserted into the case 3.

• the inserting station 5 may be fixed; or it may be movable, and paired with respective feeding means 5 b of any type known in the art.
• the supporting means 2 comprise positioning members 7.
• the positioning members 7 are suitable for positioning the case 3 in a configuration in which the supporting flank 3a is inclined to a predetermined angle a with respect to a horizontal plane A.
• each case 3 in the aforesaid inclined configuration prevents that the sachets 4 placed therein may accidentally move or partially or completely come out of the case 3 during the operating steps of packaging unit 1 operation.
• the positioning members 7 comprise at least a first surface 7a, to which the supporting flank 3a of the case 3 adheres.

• the positioning members 7 comprise at least one abutment element 9 for the bottom 3 c of the case 3.
• the abutment element 9 comprises the aforementioned second surface 7b.
• the abutment element 9 can be fixed, for example with respect to the wedge element 8 and therefore also with respect to the inserting station 5.
• the abutment element 9 can also be movable towards or away from the inserting station 5.
• the positioning of the case 3 with the supporting flank 3a inclined by a predetermined angle a with respect to the horizontal plane A allows the sachets 4 to be retained inside the case 3 in a particularly stable configuration, in which any vibrations or inertial actions transmitted to the sachets 4, due to the operation of the packaging unit 1 , can not cause displacements such as to cause instability or poor balance conditions inside the case 3 itself.
• An object of the present invention is also a packaging machine comprising at least one packaging unit 1 having the features described above.
• the packaging machine comprises conveyor means 10 of each case 3 from and/or towards the inserting station 5.
• the conveyor means 10 can be, for example, of the belt, chain, strap type, or the like.
• the positioning members 7 can be connected to the conveyor means 10.
• the positioning members 7 can be released from the aforementioned conveyor means 10, that is, in a fixed position with respect to the inserting station 5.
• the operation of the packaging unit 1 according to the invention is, in the light of what has been described, entirely intuitive.
• the sachets 4 are fed in a predetermined number to the inserting station 5; each case 3 is taken, for example, from a store by the conveyor means 10, which lead it to the inserting station 5 in a box-like configuration - substantially a parallelepiped with an open side 3b.
• the positioning members 7 allow the case 3 to be kept resting on the flank 3a in an inclined configuration according to the angle a with respect to the horizontal plane A: this ensures, once the cases 3 are filled with the sachets 4 through the inserting means 6, that the sachets 4 stay always inside the case 3, without being able in any way to move uncontrollably or even come out, for example, due to the vibration generated during the operation of the packaging machine.
• FIG. 1 Another embodiment of the packaging unit 1 according to the present invention is illustrated in Figure 4.
• This embodiment differs from that of Figures 1-3 in that the positioning members 7 further comprise lateral abutment means 11 for the case 3.
• the lateral abutment means 11 prevent any accidental movement of the case 3 transversely to the direction of insertion of the sachets 4 inside it.
• FIG. 5 Another embodiment of the packaging unit 1 according to the present invention is illustrated in Figure 5.
• the positioning members 7 comprise at least one plate element 12.
• the plate element 12 comprises an upper face, which in turn comprises the aforesaid first surface 7a.
• the aforesaid plate element 12 comprises an abutment element 9, which defines a second surface 7b on which the bottom 3c of the case 3 rests.
• the plate element 12 can be of any shape and size, without any particular limitations.
• the plate element 12 can be supported by fixed parts of the packaging unit 1, or by the base of the packaging machine.
• the plate element 12 could be replaced by another element having a different shape but technically equivalent thereto.
• Figure 6 shows an embodiment of the invention in which the positioning members 7 are incorporated in the packaging machine conveyor means 10. More in detail, the conveyor means 10 - e.g. of the belt, chain, strap type, or the like - comprise the positioning members 7, and in particular the cross section of the conveyor means 10 is substantially wedge shaped, like in the embodiments shown in Figures 1-4.
• the conveyor means 10 e.g. of the belt, chain, strap type, or the like - comprise the positioning members 7, and in particular the cross section of the conveyor means 10 is substantially wedge shaped, like in the embodiments shown in Figures 1-4.
• FIG. 7 Another embodiment of the packaging unit 1 according to the invention is shown in Figure 7.
• the positioning members 7 comprise a plate element 12, or an element technically equivalent to it.
• the positioning members 7 comprise inclination means 13.
• the inclination means 13 are suitable for selectively bringing the first surface 7a of the plate element 12 from a position in which the supporting flank 3 a of the case 3 is parallel, or substantially parallel, to the horizontal plane A, and in which the insertion of the sachets 4 inside the case 3 is carried out, to a position in which the supporting flank 3a is inclined to a predetermined angle a with respect to said horizontal plane A.
• the sachets 4 are inserted into the case 3 when the latter is in a horizontal configuration (i.e. with the support side 3a parallel, or substantially parallel, to the horizontal plane A), and the same is then brought to the inclined position by a predetermined angle a with respect to the horizontal plane A once the sachets 4 (all or only some of them) have been inserted into the case 3.
• the advantages of this solution mainly consist in the fact that insertion of the sachets 4 in the case 3 occurs in a facilitated condition: normally, the inserting means 6 work in a horizontal or substantially horizontal direction, and therefore inserting stations 5 of a pre-existing type can be used.
• inclination means 13 of the case 3 can be operated only when necessary: for example, it is possible to choose to tilt the case 3 only when a certain number of sachets 4 has been inserted inside it, or when the case 3, already filled with sachets 4, is about to be transferred to a downstream operating station, or in any other operating phase in which this may be of some use.
• the inclination means 13 can comprise, for example, a base 14; the base 14 can be connected to the conveying means of cases 3, or it can also be released from same. Moreover, the inclination means 13 comprise an articulation axis 15 provided between the base 14 and the plate element 12 on which the case 3 rests.
• actuator means may be provided which rotate the plate element 12 with respect to the base 14.
• predetermined angle a This allows the predetermined angle a to be varied according to the different application requirements, for example when the dimensions of the case 3, the number of sachets 4 contained, and other things, vary.
• the inclination means 13 can comprise a fixed element, integral with the framework of the packaging unit, and conveyor means, provided with a plurality of housings for respective cases 3.
• the conveyor means are movable with respect to the fixed element; the latter is shaped in such a way as to determine a change in the inclination of the flank 3a when the cases 3 come into contact with it, pulled by the conveyor means.
• the fixed element can be shaped like a profile of a linear cam, in which the cases, pulled by the conveyor means, act as followers; therefore, the inclination of the flanks 3a of the cases shifts from a horizontal position to an inclined one and vice versa, in the production steps in which this is required, due to the relative motion of the cases 3 with respect to the fixed element.
• FIG. 8 Another embodiment of the packaging unit 1 according to the invention is shown in Figure 8.
• the positioning members 7 comprise vacuum-operated gripping means 16.
• the vacuum gripping means 16 are suitable for keeping the case 3 in a configuration in which the supporting flank 3 a is inclined to a predetermined angle a with respect to the horizontal plane A.
• the vacuum gripping means 16 comprise at least one gripping surface 17 suitable for adhering to the supporting flank 3 a of the case 3.
• the embodiment of Figure 8 comprises a wedge-shaped element 8 such as that described with reference to the embodiments of Figures 1-4; the gripping surface
• the gripping surface 17 can comprise holes or openings 18 through which the vacuum gripping means 16 act, through respective channels 19.
• the vacuum gripping means 16 allow the case 3 to be kept in the desired position in a more stable and safe manner; thanks to this, the positioning members 7 can be constructively simpler (for example, an abutment element may not be necessary for the bottom of the case 3).
• FIG. 9 Another embodiment of the packaging unit according to the invention is shown in Figure 9.
• This embodiment differs from that of Figure 8 in that the positioning members 7 comprise a plate element 12 retaining the supporting flank 3a of the case 3.
• the vacuum gripping means 16 with characteristics similar to those described for the previous embodiment operate through the plate element 12.
• the packaging unit 1 according to the embodiment of Figure 9 can further incorporate inclination means 13 such as those of the embodiment of Figure 7.
• the solution adopted is especially advantageous since the vacuum gripping means 16 firmly retain the case 3 and prevent accidental movements during its inclination operation.
• FIG. 10 Another embodiment of the packaging unit 1 according to the present invention is shown in Figure 10.
• the positioning members 7 comprise at least a first supporting element 20 and a second supporting element 21 of the flank 3 a of the casing 3.
• the first supporting element 20 and the second supporting element 21 comprise respective end portions supporting the flank 3a of the case 3, positioned at different heights with respect to the horizontal plane A.
• the first supporting element 20 and the second supporting element 21 can be mutually connected to each other by a central section 22, or by other connecting elements.
• the supporting elements 20,21 can be connected to the conveyor means 10 of the cases 3 - as shown in Figure 10 - or they can be released from same.
• At least one of the first supporting element 20 and the second supporting element 21 is selectively movable between a lowered position, in which the flank 3 a of the case 3 is parallel, or substantially parallel, to the horizontal plane A, and in which the sachets 4 are inserted into the case 3, to a raised position in which the flank 3 a is inclined by a predetermined angle a with respect to the horizontal plane A.
• the first supporting element 20 in particular can be selectively movable between the two above mentioned positions.
• Figure 11 shows another embodiment of the packaging unit 1 according to the invention which differs from that of Figure 10 in that in the positioning members 7 the second support element 21 is substantially at the same height as the central section 22; moreover, the abutment element 9 is made to be integral with the same central section 22.
• the positioning members 7 are incorporated in the conveyor means 10 of the cases 3.
• Figure 12 shows as a cross section an example in which the conveyor means 10 comprise a belt, or a chain, a strap, or the like (seen in cross- section); the positioning members 7 comprise a first edge 23 and a second edge 24 of the belt, or chain, or strap, which reach different heights with respect to the horizontal plane A, and therefore allow the case 3 to be positioned in the desired inclined configuration.
• the predetermined angle a can be comprised between 1 ° and 70°.
• the invention greatly limits the risk that the sachets inserted in the case can move or come out accidentally during the packaging operation steps.
