Definitions

  • the present invention concerns a method to separate wrappings, such as for example sachets, double sachets, bags.
  • the wrappings are suitable to contain solid substances in powder, granule or tablet form.
  • the substances may be, by way of non-restrictive example, drugs, supplements, food preparations, for both human and animal use, cosmetics, substances for washing and disinfection, chemical or biological substances, whether dangerous or not, and suchlike.
  • the present invention also concerns an apparatus for separating wrappings which implements the method according to the present invention, and a packaging machine comprising said apparatus.
  • These known machines or lines usually comprise a machine or processing station located upstream, for example a filling station in which the wrappings to be packaged are filled.
  • the filling station is usually suitable to load or form a wrapping inside which the substances with which the wrapping has to be filled are inserted.
  • the filling station After filling, the filling station usually provides a panel, or matrix, of wrappings, consisting of a series of rows and columns of wrappings filled and attached to each other.
  • the panel of wrappings is then received by an apparatus for separating the wrappings, which first cuts it into strips of wrappings, and then separates said strips further, into individual wrappings, where each strip consists of a single column of wrappings of said panel.
  • the apparatus for separating the wrappings then picks up each individual wrapping to send it toward one or more exit conveyor means, said means being typically conformed as movement lines of a known type.
  • the conveyor means transport the wrappings to a machine or processing station located downstream, for example a packaging station in which the wrappings to be packaged are disposed in an orderly manner inside boxes or cartons or flexible packages.
  • the separator apparatus can comprise separator means to separate the wrappings, and gripping means to pick up the separated wrapping.
  • known methods can provide to let it fall by gravity for a more or less long segment toward the gripping mean.
  • the gripping mean then intercepts the wrapping and grips it, transporting it far from the strip of wrappings.
  • the gripping position is not optimal, because for example the wrapping is gripped in an incorrect position, for example too close to an edge, or with an incorrect angle.
  • this can happen because, when it falls, the wrapping can assume a random, uncontrollable orientation, which can also represent a non-optimal configuration for gripping.
  • the subsequent operations to transport and package the wrappings can also be made more difficult.
  • Another disadvantage of the state of the art is also due to the fact that, in order to reduce the number of failed or incorrect gripping operations, the speed of the cutting process must be decreased, also slowing down the packaging process overall.
  • separator apparatuses can be configured, in an initial set-up step that precedes the production of a batch of wrappings having a certain size, so that the gripping means are located in a fixed position such as to allow them to grip the wrappings before they are separated from the corresponding strips.
  • the separator apparatus is suitable to process only wrappings of a certain size, and with each change in the format of the wrappings, the gripping means must be suitably repositioned in a position correlated to the sizes of the new wrappings to be processed.
  • the positioning of the gripping means requires long and laborious set-up operations, with consequent long downtimes of the machine.
  • Document JP2007191197 shows an apparatus for separating sachets from a strip of sachets in which a gripping member is configured to grip a sachet in correspondence with a cutting station, and to translate in a diagonal direction in order to take the gripped sachet toward a conveyor belt at exit from the apparatus.
  • this apparatus provides that the sachets are filled and sealed in correspondence with the cutting station, in which a cutting device is equipped with suitable sealing means. This necessarily implies an intermittent feed of the sachets.
  • it is not precisely specified at what moment the gripping member grips the sachet with respect to cutting and sealing.
  • Document DE 1020108202021 shows a gripping device which comprises an articulated arm with two joints, and equipped with a gripping head with suction cups.
  • the articulated arm allows a wide range of movements of the article that is gripped by the gripping head.
  • US patent 8631633 describes a sealing unit to close individual sachets, comprising in succession a sealing device, a cutting device and a device to grip the separated sachet. Downstream of the latter a gripping and feed member is provided, which grips the lower edge of the sachet while it is closed in its upper part, and draws the sachet to bring the upper edge into correspondence with the cutting device.
  • a gripping and feed member is provided, which grips the lower edge of the sachet while it is closed in its upper part, and draws the sachet to bring the upper edge into correspondence with the cutting device.
  • the sachet is held in position by abutment members of the cutting device, to be subsequently gripped by a gripping member equipped with a suction cup which grips the sachet laterally.
  • a gripping member like this does not allow to guarantee the correct positioning of the sachet in the following exit station.
  • Document GB 1271214 shows an apparatus for separating sachets in which the sachets are filled, sealed and cut in correspondence with a cutting station.
  • a rotary gripping device is provided, which takes, by means of a suction cup, the sachet that has just been cut and, by means of a rotation of about 90°, deposits it in a receptacle located immediately below.
  • the gripping device providing a suction cup, does not allow to guarantee the correct positioning of the sachet even though it is configured to move it over a minimum distance.
  • the configuration of this apparatus does not allow to easily process sachets of various sizes.
  • one purpose of the present invention is to improve the grip of the wrappings that have been separated from the strip of wrappings, preventing the free, that is, unaccompanied or controlled, fall thereof.
  • One purpose is also to facilitate the operations to transport and insert the wrappings into the packages following the intervention of the gripping means.
  • One purpose of the invention is also to speed up the packaging processes, both by avoiding unwanted blockages of the packaging machine, and also by increasing the speed of the cutting process as far as possible.
  • One purpose is also to avoid long and costly machine downtimes in order to provide the correct configuration of the gripping means.
  • Another purpose of the present invention is to provide a packaging machine comprising an apparatus for separating wrappings able to obtain the purposes indicated above and to carry out the corresponding method to separate wrappings.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • some embodiments described here concern a method to separate sealed wrappings able to contain substances, such as for example powder, granules, tablets, in particular of a foodstuff, pharmaceutical or cosmetic nature for a machine that packages wrappings, which overcomes the limits of the state of the art and eliminates the defects present therein.
  • Some embodiments described here also concern an apparatus for separating wrappings and a packaging machine that comprises it, which implement the method according to the invention.
  • the method to separate wrappings provides that, in a known manner, a panel of wrappings configured as a matrix of wrappings, comprising a plurality of rows and columns, is cut into strips of wrappings along cutting directrices parallel to a direction of feed.
  • the method provides that the strip of wrappings is fed toward separator means in the direction of feed.
  • the strip of wrappings is fed with a continuous motion, but an intermittent motion can also be provided.
  • the separator means when the wrapping has arrived in a separation zone, in correspondence with which the separator means penetrate in the strip in order to separate the wrappings from the latter by acting along a cutting directrix oriented according to a transverse direction with respect to the direction of feed as above, the separator means are driven, separating the wrapping from the strip of wrappings.
  • the method provides to grip said wrapping with gripping means.
  • the method provides that the gripping means as above are supported by mobile support arms and also provides to move these arms according to a movement having at least one linear translation component, in particular parallel to a directrix of vertical movement, in such a way as to alternately move the gripping means closer to or away from the wrapping.
  • the method therefore provides that the gripping means grip the wrapping before it is completely separated from the strip and accompany it, once separated, toward exit conveyor means.
  • the exit conveyor means as above can be configured as a line for moving the wrappings toward a working machine or station located downstream.
  • the method provides to drive the gripping means in rotation about an axis of rotation, so that the gripping means follow a trajectory defined by the combination of at least the linear translation component of the mobile arms and the rotation of the gripping means, in order to define a rotary-translational motion.
  • the rotation of the gripping means as above can occur according to an oscillatory movement.
  • the wrapping can be gripped when it is anchored, at least in a part thereof, to the strip of wrappings, so that its position and angle are known and controlled, thus allowing a better and repeatable grip.
  • a further advantage consists in the fact that the separation speed can be increased, since it is not necessary to control the separation process in order to prevent the wrapping from moving excessively from the predefined position for the grip by the gripping means.
  • Yet another advantage of the method and of the apparatus according to the present invention is that of being very flexible during use, because they can work wrappings of different sizes without requiring any set-up operation of the gripping means whatsoever.
  • the method provides that the separation is carried out according to a scissor-like movement along a transverse edge of the wrapping that connects two lateral edges of the latter.
  • the method provides that the separator means affect the entire separation zone at the same time, thus providing a clear separation of the wrapping from the strip of wrappings by means of a shearing that simultaneously affects the entire transverse edge. This causes the newly separated wrapping to fall straight, that is, without being at all inclined with respect to its position before the cutting.
  • the method provides that the gripping means grip the wrapping in correspondence with a part thereof that is distanced from, preferably opposite, the part in which the separation of the wrapping by means of the separator means occurs. More preferably, the grip of the wrapping, carried out by the gripping means, occurs in correspondence with the edge opposite the edge where the separation of the wrapping takes place.
  • an apparatus for separating wrappings in particular configured to perform the method as above.
  • the apparatus comprises a cutting assembly equipped with separator means able to separate strips of wrappings into the individual wrappings, and a gripping assembly which comprises gripping means configured to grip the individual wrapping, and mobile support arms able to support the gripping means.
  • the arms are mobile at least in a direction of linear translation, in particular parallel to a directrix of vertical movement, so as to alternately move the gripping means closer to or away from the wrapping, so as to respectively allow the gripping means to grip the wrapping before it is completely separated from the strip, and accompany the separated wrapping toward exit conveyor means.
  • the gripping means comprise an attachment and a gripper gripping mechanism.
  • the gripping mechanism advantageously comprises two portions, each one mobile with respect to the other between a non-operative position, in which the portions are reciprocally distanced, and an operative position, in which the portions are clamped in order to grip the wrapping.
  • the gripping assembly comprises a shaft rotatable about an axis of rotation and constrained to the arms by means of pins, and the gripping mechanism is constrained on the shaft by means of the attachment.
  • the gripping means are configured to rotate about the axis of rotation as above, in order to accompany the wrapping resting on the exit conveyor means.
  • apparatus 10 for separating wrappings 100 for a packaging machine, hereafter referred to as apparatus 10, is described.
  • the sealed wrappings 100 are able to contain substances, for example powder, granules, tablets, typically of a foodstuff, pharmaceutical or cosmetic nature.

  • the disc elements 13 are configured to rotate on a plane perpendicular with respect to the panel 101 and to cut said panel 101 along separation lines 103 in correspondence with the longitudinal sealing lines of the wrappings 100.
  • the separator means 14 can be configured, in a known manner, to separate the strips 102 into the individual wrappings 100. This separation occurs along a line transverse to the panel 101, that is, transverse to a direction of feed of the strip 102, as will be explained in more detail below.
  • the separator means 14 can be substantially similar to the cutting means 13, and therefore comprise disc elements, rotating elements, elements for laser cutting, scissor elements and suchlike.
  • the separator means 14 are configured as a rotating element with an axis of rotation perpendicular to a direction of feed D1 of the strip 102.
  • the rotating element 14 can have at least two projecting elements 15 on its external surface.
  • the projecting elements 15 can be configured with a cutting end 16, able to separate the wrapping 100 from the strip 102.

  • the projecting elements 15 can be configured in directions that are not perpendicular to each other, so as to present, during the rotation of the separator means 14, a single point of contact which moves in the direction of the cutting.
  • the separator means 14 are configured as shearing means able to affect the entire separation zone at the same time, thus providing a clear separation of the wrapping 100 from the strip 102 by means of a shearing that simultaneously affects the entire transverse edge 105.
  • the projecting elements 15 can extend parallel to each other, so as to be in contact with each other for the entire extension of their cutting end 16, during the separation of the wrapping 100 from the strip 102.
