Definitions
- the material falls under gravity from an hermetically sealed degassing and weighing chamber mounted above the filling chamber, passing through a tube into the bag.
- the neck of the filled bag is heat-sealed under vacuum in the filling chamber by two sealing heads.
- the sealed, filled bag is then removed from the filling chamber by opening the door and the bag is removed from the enclosure by a suction plate which grips one side of the bag.
- the bag can be inflated before insertion into the enclosure in order to produce its maximum volume.
- PACKAGING MACHINE BACKGROUND OF THE INVENTION This invention relates to packaging materials of low mesh size in bags of flexible material. It relates to a machine for such packaging.
- Pulverulent or granulated products such as cements, lime, sugar, flour and granulated plastics material are normally packaged either in paper, plastics or plasticized jute bags etc. in the case of small amounts (less than lOkg.), or in vessels made of metal, reinforced plastics or reinforced concrete, such as containers or silos, in the case of greater amounts.
- these finely divided products takes place either in bags for small amounts or finely divided amounts or in vessels made of metal or possibly reinforced plastics for larger amounts. In the latter case, whether they are conveyed by road, rail, waterway or sea, the vessels are generally permanently mounted on specialized transportation appliances.
- the time required for creating the vacuum does not make it possible to envisage an economical industrial exploitation.
- the dura tion of the operation depends on the volume to be packaged and on the pressure drop undergone by the evacuated air, this pressure drop being particularly dependent on the dimensions of the inter-granular spaces. In the case of a material having a low mesh size, these dimensions are very reduced and even tend to decrease as the value of the vacuum increases, under the action of atmospheric pressure exerted on the walls of the enclosure.
- the new machine comprises:
- At least one door for opening the second chamber, allowing introduction of the bag therein and to bring the neck of the latter under the discharge pipe;
- each bag is inflated before filling to produce its maximum internal volume.
- Packaging may also take place with a controlled gaseous atmosphere.
- the packaging time itself is shorter, since the volume of gas to be eliminated is less.
- the volume of material does not vary during its packaging and it is possible to give the packaging enclosure a well defined shape before filling, so that it has at least one flat face for gripping by the nozzle. For the same reason, it is thus possible to use containers which are lessflexible, thus thicker and stronger than the sheet of plastics material used in the known methods.

- DESCRIPTION OF PREFERRED EMBODIMENT Bags 2 used for packaging material in accordance with the present invention have a shape such that they may be conveyed with reduced volume when they are empty. When they are full, they preferably generally cubic shape, as shown, and have at least one flat side enabling them to be gripped by a suction plate.
- substantially cubic bags 2 made from flexible polyethylene of 1 mm. thickness. This thickness is sufficient to make the bag impermeable to gases and to facilitate prolonged storage; it also provides good resistance to impact and to wear.
- each'bag As shown in FIG. 1 has a cylindrical neck 3 on a vertical axis, connected to the lateral faces of the bag by a surface in the form of a pyramid.
- the bags are hung from an endless cable 1, 4 by clips 5, each acting on the wall of a bag in the vicinity of the upper edge 6 of the neck 3 (see FIG. 1
- each bag is manually detached in order to be subjected to an inflating operation intended to provide its maximum internal volume and to eliminate as far as possible the folds which may have formed on its outer surface and which could be detrimental to subsequent manipulation by a suction plate.
- each bag is engaged manually on the lower end portion 8 of a vertical tube 7 at the upper end of which a blower 9 blows in air.
- a microswitch (not shown) causes inflation of an annular seal 10 placed around and secured to the tube 7, at its lower end 8 (see FIG. 2).
- This seal 10 shown deflated in FIG. 2, bears against the inner wall of the neck which it keeps on the air supply tube 7.
- the same air supply tube 7 is used to put each bag in position in the machine proper.
- the supply tube is mounted to slide on parallel guide bars 11 and 12 which make it possible to supply the bag above the machine and the lower end portion 8 of each tube 7 has telescopic, slidable fit with the tube itself to lower the bag into the machine.
- the machine proper comprises two identical packaging chambers 13 and 14, surmounted respectively by chambers 15, 16. Each chamber l5, 16 is disposed for removing gas from, and for weighing, the material to be packaged.
- the packaging chambers 13, 14 are connected to the degassing and weighing chambers l5, 16 respectively, by vertical pipes 18,19 for discharging the material to be packaged.
- the two packaging chambers 13 and 14 are located side-by-side in a single cylindrical enclosure 17 on a horizontal axis. They are separated from one another by a hermetic transverse partition 17', but are interconnected by a pipe 56 provided with a valve 57 whose purpose will be described hereafter.
- the two ends of the enclosure 17 may be closed hermetically by vertical circular closure means or doors 20 and 21, mounted on ball sockets sliding on horizontal steel bars 22 and 23, 24 and 25, and disposed to be moved along these bars by jacks such as 26.
- each door for example the door 20, is rigidly connected with a vertical basket or enclosure 27 whose inner dimensions are the outer dimensions of the cubic part of the bag and whose upper end is open, in order to facilitate the introduction of a bag 2 vertically, by means of the telescopic air supply tube 7, 8 when the door 20 is open.
- a basket or enclosure 27 It is the purpose of the basket 27 to retain the walls of the bag during the filling, in order to prevent the formation of folds which may be detrimental to subsequent gripping by means of a suction plate.
- each basket or enclosure 27 is provided with a vibrating table 92 intended to facilitate settling of the material in the bag 2 during packaging.
- the basket 27 is also open at one of its side faces, for example the side 32, in order to facilitate the subsequent gripping of the filled and sealed bag by a device having a vertical suction plate such as 28.
- a vertical plate 29, mounted inside the chamber 13 on a horizontal jack (not shown) closes this open side 32 to ensure that the bag 2 is retained over its entire periphery.
- FIGS. 3 and 4 show that the end closure door 20 is provided with a device intended to retain the neck of the bag while the bag is filled. In fact, this operation cannot be carried out by the telescopic tube 7, which must be extracted from the neck of the bag before closing the door 20 and after the seal 10 has been deflated.
- the neck-retaining device comprises two arcuate members 30 and 31 which, when they are in position, form a horizontal circular ring fitted on the upper edge 6 of the neck of the bag.
- Each arcuate member comprises a rib 34, which engages the edge of the neck 6 (see FIG. 2).
- An inflatable seal 35 fitted in the rib, bears against the latter, on the outside, in order to press it tightly against an edge 36 of the rib located inside the neck.
- Each of the two members 30 and 31 of the ring is integral with an oblique arm, 37 and 38, respectively, mounted to rotate about a vertical cylindrical shaft 39 and 40 respectively, integral with a horizontal cross member 45 arranged parallel to the general plane of the door 20.
- An abutment 48 and 49 respectively integral with the cross member 45, limits the movement of the cam and makes it possible to obtain a predetermined position for retaining the neck accurately.
- the cross member 45 supporting the arms 37, 38 is able to move vertically under the action of a vertical jack 50 bearing, on the one hand, against the lower side of the movable cross member 45 and, on the other hand, against a second cross member 51 integral with the door 20.
- Guidance of the movable cross member 45 during this vertical movement is ensured by shafts 39 and 40, extended under the cross member 45 and able to slide in vertical cylindrical apertures in the fixed cross member 51.
- the bag whose sides are retained by the walls of the basket 17 and by the movable plate 29 and whose neck 3 is retained by the gripping members 30 and 31, is placed in the filling position, the opening of the neck being located immediately below the pipe 18 for discharging the material to be packaged.
- the lower part of the discharge pipe 18 is provided with a telescopic tubular member 33, coaxial with the pipe 18 and mounted to slide vertically along the latter.
- the telescopic member 33 is engaged vertically in the neck 3 of the bag before filling the latter and makes it possible to prevent to a maximum losses of material to be packaged from the bag.
- the vertical movement of the member 33 is controlled by two diametrically opposed synchronised jacks, such as 52, acting between a fixed frame 53 and a ring 54 integral with the member 33.
- the ring 54 is guided in its vertical movement by vertical cylindrical rods such as 55, on which it is slidably mounted.
- the discharge pipe 18 connects the packaging chamber 13 to the chamber for removing gas and weighing.
- the two chambers may be separated by a hermetic valve 63 located in the discharge pipe 18 (see FIG. 6).
- the chamber 15 for removing gas and weighing, with which its counterpart 16 is identical, is defined by a wall in the form of a vertical truncated funnel 58 surmounted by a vertical cylinder 59 closed at its upper part by a cover 60.
- the vacuum source 93 can be replaced by other means for maintaining a controlled gaseous atmosphere, for the packaging of certain finely divided materials.
- Opening into the cover 60 is the lower part of a chute 61 which receives the material from which gas is to be removed and which is to be packaged, the chute 61 being able to be separated from the chamber 15 by a hermetic valve 62.
- a hermetic valve 62 In practice, it is appropriate to always keep the chute 61 full, in order that opening the valve 62, at the time of introducing material into the chamber 15, does not cause the simultaneous entrance of too great a quantity of air.
- the raw material introduced through the valve 62 is collected by a vertical funnel 67, whose lower part is in the form of a cylindrical pipe 68 coaxial with the discharge pipe 18, closed by a valve 69.
- the funnel 67 is mounted on a weighing machine of known type, not shown in FIG. 6, but shown diagrammatically by a dial 70 in FIG. 1. (and by a dial 71 in the case of the degassing and weighing chamber 16), this device making it possible to introduce into the chamber 15, then into the packaging chamber 13, through the intermediary of the valve 69 and valve 63, the quantity of material corresponding exactly to the quantity to be packaged in one bag.
- a dial 70 in FIG. 1 and by a dial 71 in the case of the degassing and weighing chamber 16
- the bag Once the bag has been filled, it is sealed transversely under vacuum in the vicinity of its neck 3 by means of a device contained in the chamber 13 (the chamber 14 contains an identical device).
- the neck 3 which is originally cylindrical, a flattened shape in order for it to have two joined walls.
- two hooks 72 which are diametrically opposed with respect to the axis of the neck are used, acting vertically in a plane which in this case is perpendicular to the plane of the jacks controlling the telescopic member 33 of the discharge pipe 18.
- the hooks 72 are placed on the edge 6 of the neck 3, inside the latter, at the two ends of the diameter of the latter. They are interposed between the two members 30 and 31 for gripping the neck (FIG. 4).
- the neck is sealed by two rectilinear sealing heads 82, located horizontally opposite each other, parallel to the two joined walls which form the neck 3 after preparation, i.e. parallel to the vertical plane in which the two hooks 72 act.
- These two heads located at the upper part of the packaging chamber 13, inside the latter, are moved towards the neck by two jacks 96, (FIG. 1) acting horizontally below the level in which the hooks 72 act.
- FIG. 7 is a cross section of one of the heads 82.
- a longitudinal sealing strip 85 Located inside a U-shaped longitudinal section 83, whose opening is directed towards the neck of the bag and insulated from this section by a heat-resistant material 84, is a longitudinal sealing strip 85.
- a longitudinal electric resistance element 86 is provided inside the sealing strip 85 .
- a longitudinal plate 87 is provided inside the sealing strip 85 .
- the active part of the sealing strip 85 projects from the section 83 and it is provided, at the point where it is intended to come into contact with the material strip to be sealed, with a rod 88 of a material intended to 'transmit the heat necessary for sealing, whilst able to be readily detached from the sealed material, before coolmg.
- Rods 88 of PTFE filled with a conducting material such as bronze heated to the melting point of the film of polyethylene, namely 130 to 150C, the strips being applied under a pressure of the order of about 10 kg/cm
- Rods 88 firstly cause melting of the wall of the polyethylene, penetrating therethrough under the action of jacks 96. They have contours 88a and 88b (FIG. 8) causing a flow of the melted material to promote thorough sealing, for example in the regions 101 of the two joined walls of the neck 3.
- the penetration extends for several dozen mm., then it is limited by longitudinal abutments such as 89, fixed laterally to the section 83. As they are sufficiently close to each other, they thus cause the sealing proper. An operating process of this type makes it possible to seal walls of great thickness.
- An abutment plate 94 is interposed between the sealing strip 85 and the heat insulation 84 located at the base of the section 83, in order to distribute the stress on the insulation as well as possible.
- a sheet of shock-absorbent material 95 is interposed between the base of the section 83 and the insulation 84 in order to prolong the sealing action by applying slight pressure after the abutments 89 have come into contact.
- a valve, 90 and 91 respectively, FIG. 1, makes it possible to connect each packaging chamber 13 and 14 respectively, with the open air.
- each packaging chamber 13 and 14 Located at the side of each packaging chamber 13 and 14 is a handling device comprising a suction plate.
- a handling device comprising a suction plate.
- Each of these devices for example the arrangement associated with the chamber 13, is composed of a support 97 on which is mounted a vertical suction plate 28, capable of rotating with respect to a vertical shaft integral with the support 97.
- the support 97 slides on two horizontal rails 98 and 99, perpendicular to the general direction of the guide bars 22 and 23 of the door 20.
- the arrangement is such that the suction plate 28 adheres against the side of the bag left free by the basket 27, when the door 20 is open.
- One rotation of the suction plate 28 thus makes it possible to move the bag to a point where it may be discharged by a known system.
- the bags 2, supplied by the supply chain 1, are manually unhooked in order to be fixed by their neck 3 on the lower end 8 of the vertical blowing tube 7.
- a micro-switch located on the tube 7 causes the inflation of the seal 10 placed around the lower end 8 of the tube 7. This seal 10 bears against the inner wall of the neck, which it presses against the tube 7 throughout the period of inflation.
- the bag is also retained by the seal 10 whilst being put in position in the basket 27 of the machine.
- this positioning is effected by sliding the tube 7 on guide bars 11 and 12, this sliding bringing the bag above the basket 27, then by telescopic elongation of the lower part 8 of the tube 7, this elongation causing the downwards movement of the bag into the basket.
- the jacks 41 and 42 acting on the cams 43 and 44 respectively, bring about the positioning of the gripping members 30 and 31 above the edge 6 of the neck 3 of the bag, the inner seal 35 being deflated.
- the jack 50 brings about the downwards movement of the cross member 45 and thus the downwards movement of the two members 30 and 31 which engage the edge 6 of the neck.
- the inner seal 35 of the gripping members is then inflated, retaining the neck in the stationary position.
- the seal 10 of the telescopic blowing tube 7 is then deflated and the tube 7 moved upwards.
- the door 20 is then reclosed, by the action of the jack 26. With its closing movement it entrains the basket 27 and the bag which it contains, and the neck of the bag is placed directly below the lower part of the discharge pipe 18 at the end of this closure.
- the telescopic connection 33 of the discharge pipe 18 then moves downwards, under the action of jacks 52 in order to engage in the neck 3 of the bag.
- the two books 72 complete the first stage of their downwards movement underthe action of jacks 73 and are placed on the edge 6 of the neck.
- the equalizing valve 57 is then closed. One then opens the valve 63 providing a connection between the packaging chamber 13 and the weighing and degassing chamber 15, which is always under vacuum due to the action of the pump 93. At this time, the finely divided material to be packaged contained in the funnel 67 has already been in the chamber 15 for a sufficient period of time to have been degassed: it is thus ready to be packaged.
- the valve 69 is then opened and the material to be packaged drops into the bag, in a quantity predetermined at the time of weighing, which is carried out in the chamber 15, before opening the valve 63.
- the bag is filled quickly and without dust, owing to the vacuum and to the short gap separating the outer wall of the telescopic tube 33 from the inner wall of the neck 3'.
- a vibrator 92 is started up, which causes settling of the material in the bag and makes it possible to obtain flat faces which bear perfectly against the walls of the basket 27.
- a new weighing operation may then be undertaken in the chamber 15, by opening the measuring valve 62 for connecting the chute 61 and the weighing funnel 67.
- the output of the supply devices for the chute 61 of material to be packaged is such that this chute is always full, whereby vacuum losses at the time of this introduction are minimal.
- the two sealing heads 82 are brought together by jacks acting horizontally. In a first stage, they penetrate the wall of the neck of the bag by causing this wall to melt, until the abutments 89 are pressed against the wall. In a second stage, when the heads are sufficiently close to each other, the two joined walls are sealed.
- the equalizing valve 57 is opened to establish a first partial vacuum inside the chamber 14, whose operating cycle is alternated with that of the chamber 13.
- vertical jacks 73 and 76 bring about the return of the hooks 72 to their upper position, whereas horizontal jacks 81 cause them to return to their position in grooves of the telescopic tube 33.
- the equalizing valve 57 is re-closed, then the valve 91 for connecting the chamber 13 to the outside air is opened.
- the jack then causes the translation of the suction plate 28 towards the full bag, the suction plate bearing against the free side of the latter.
- a vacuum is established between the suction plate 28 and the wall of the bag against which it is applied, a jack lifts the arrangement, then the support 9'7 of the suction plate is returned to its original position by means of the jack 100.
- the suction plate 28 is then caused to rotate on its support to a new position 28a in order to bring the bag into the discharge region; atmospheric pressure is reestablished between the suction plate 28 and the bag, which is released.
