Definitions

  • This invention relates to a packaging machine and a method for making a package which includes a bag made of flexible material filled with a dose of loose product and coupled with a respective spout.
  • loose product means a product with a low cohesion, that is, low adherence between its constituent parts, and therefore without its own shape: it may be a liquid, semi-liquid, grated or powdered product.
  • An automatic packaging machine for making a package which includes a bag made of flexible material filled with a dose of loose product is known from patent document EP3257764A1 , in the name of the same Applicant.
  • the machine comprises, on a rotary carousel, at least one filling device designed to feed the dose of product inside the bag through its open top end, and at least one sealing device designed to seal the full bag by means of a sealing at the open top end, after feeding the dose of product.
  • the sealing device is associated with a device for feeding a cap.
  • Patent document US4283901A provides a rotary machine for filling a bag with a cap associated with a spout, formed in advance, removing the cap from the spout and filling the bag through the spout; this machine must be supplied with bags already formed, with respective spouts already fixed; consequently, it must be integrated in a production line which provides another machine dedicated to the formation of the bags, with a consequent increase in the overall dimensions and complication of the production line. Moreover, if the bag already formed remains empty for a long time before being fed to the filling machine, the walls can adhere to each other causing escape of product from the spout, during filling.
  • WO 2005/014399 A1 also discloses a packaging machine according to the preamble of claim 1.
  • the aim of this invention is to provide a packaging machine and a method for making a package which include a bag made of flexible material filled with a dose of loose product, which overcome at least one of the above-mentioned drawbacks of the prior art.
  • the packaging machine is configured for making a package including a bag and a spout.
  • the bag is made of flexible material, preferably heat-sealable.
  • the bag is preferably formed starting from a multilayer sheet, comprising a layer of metallic material (for example, aluminium) and a layer of plastic material.
  • the spout is preferably formed from rigid plastic material; the spout is shaped to be associated with a cap (preferably by screwing).
  • the machine is configured for receiving the empty bag, with a top end open.
  • the bag in one embodiment is formed by a sheet of multilayer material folded back on itself (in such a way that an edge of the bag is defined by the folding line) and sealed on two of the remaining edges, leaving a remaining edge open; in this case, the open edge defines the open top end.
  • the bag is formed by a sheet of multilayer material folded back on itself and sealed on the remaining edges, leaving a corner (and part of the edges adjacent to it) open; in this case, the angle defines the open top end.
  • the bag which is fed is completely open (that is to say, it is composed of a sheet folded back on itself); in this case, the open top end is one of the open sides.
  • the machine is configured to receive, for each bag, a respective spout.
  • the machine is configured for moving the bag and the spout along a packaging path.
  • the machine comprises (at least) one sealing device.
  • the sealing device is movable along the packaging path.
  • the sealing device is configured for sealing the bag along its open top end, around the spout.
  • the flaps of the top end are joined stably to the spout, at the spout, and between each other, in the zone in which there is no spout.
  • top end of the bag has a central portion and two lateral portions (between which is the central portion); the two flaps of the top end, in the central portion, are sealed to the spout, whilst the lateral portions are sealed to each other.
  • the bag is joined stably to the spout: in fact, the spout is sealed between one flap and the other of the top end. Moreover, the bag is closed: the only passage which remains between the inside of the bag and the outside is defined by the opening of the spout.
  • the machine comprises a dispensing device.
  • the dispensing device is movable along the packaging path.
  • the dispensing device is configured for introducing the dose of product inside the sealed bag (that is to say, in its inner space) through the spout.
  • the product therefore passes, due to the dispensing device, through the opening of the spout and enters the inside of the bag.
  • the bag may be filled up to its maximum capacity.
  • the seal (or sealing) does not interfere with the product (which is subsequently introduced, with the bag already sealed), and a clean surface can be sealed, with better results both in terms of quality of the sealing and the levels of hygiene of the package.
  • the dispensing device comprises a straw.
  • the straw has an end (bottom) configured for being inserted in the opening of the spout for dispensing the dose of product inside the bag.
  • the product passes along the inner channel of the straw and comes out of the straw inside the bag (or in the spout), without be dispersed outside and/or generating splashes.
  • the straw (or its inner channel) has a cross section of passage of the product which is less than the opening of the spout. In this way, as the product is inserted into the bag, the air or the gas initially present in the bag escapes through the spout (outside the straw).
  • the additional straw comprises an additional channel for venting the air or gas initially present in the bag.
  • the additional channel may be to the side of the channel or concentric, inside or outside it.
  • the additional channel is sized to penetrate into the bag only in an upper zone, which will not be filled with the liquid.
  • the machine comprises a packaging carrousel (hereinafter also referred to as 'carousel').
  • the packaging carousel includes a plurality of seats (hereinafter as also referred to as 'seats') which are angularly spaced. Each seat is configured to receive (and retain) a bag and a respective spout.
  • Each seat (or processing unit) comprises a respective sealing device and a respective filling device.
  • the sealing device and the filling device are on-board the packaging carrousel, repeated in each seat (or processing unit) of the packaging carrousel.
  • the sealing device and the filling device of each seat (or processing unit) rotate on the carousel together with the respective seat (or processing unit).
  • the packaging path extends along a circular periphery of the packaging carrousel (from a corner for loading the bags and the spouts to a corner for discharging the finished packages).
  • the machine comprises a control unit programmed for activating in succession, for each packaging seat, firstly the sealing device and then the dispensing device, during a rotation of the packaging carrousel (and, therefore, a forward movement of the bag and the spout along the packaging path).
  • the control unit controls, before the activation of the sealing device, a gripping of the spout and its insertion in the open end of the bag, by means of a pickup element of the spout.
  • control unit is programmed for activating the sealing device of each packaging seat when the respective packaging seat is in (or enters) in a first circular sector of the carousel (the first circular sector is the same for all the seats).
  • control unit is programmed for activating the filling device of each packaging seat when the respective packaging seat is in (or enters) in a second circular sector of the carousel (the first circular sector is the same for all the seats).
  • the second circular sector is downstream of the first circular sector in the direction of rotation of the packaging carousel.
  • each packaging seat includes an arm for supporting the bag.
  • the supporting arm of the bag is configured to support the bag (during the sealing and during the filling).
  • the arm for supporting the bag is also configured for moving the bag along a radial direction, formed along a radius of the packaging carrousel, from a first radial position to a second radial position.
  • the sealing device of each seat is configured for sealing the bag positioned in the first radial position.
  • the dispensing device of each seat is configured for filling the bag positioned in the second radial position.

  • each packaging seat includes a spout gripping element.
  • the pickup element of the spout is movable along the packaging path (together with the respective seat) and is configured for receiving and retaining the spout.
  • the pickup element of the spout is preferably configured for moving the spout along a vertical direction (parallel to the weight force) for inserting it, at least partly inside the open top end of the bag. This movement includes a lowering. This movement is prior to the sealing.
  • the gripping element of the spout is, preferably, configured to insert the spout (at least partly) in the open end of the bag when the bag is in the first radial position.
  • the pickup element of the spout is preferably associated with the sealing device: in effect, the control unit firstly commands the pickup unit to position the spout inside the top end of the bag and then, whilst the pickup element retains the spout in its position, commands the sealing device to seal the top end of the bag around the spout.
  • the sealing device includes a first gripper (or first grippers) configured for closing the top end of the bag around the spout.
  • the first gripper in one embodiment surrounds the spout pickup element.
  • the sealing device includes one or more electrical resistors (preferably integrated in the first gripper) configured for heat sealing the top end of the bag (whilst it is kept closed, that is, the flaps are kept close, by the action of the first gripper).
  • the sealing device includes one or more ultrasound emitters (preferably integrated in the first gripper), configured for sealing by means of ultrasound the top end of the bag (whilst it is kept closed, that is, the flaps are kept close, by the action of the first gripper).
  • ultrasound emitters preferably integrated in the first gripper
  • This invention also provides a method for making a package which includes a bag made of flexible material filled with a dose of loose product coupled to a respective spout.
