Definitions

  • the present invention relates to a packaging machine for making up single-dose packs with break opening.
  • the single-dose packs with break opening are composed of a layer of semi-rigid plastic material superimposed on and sealed to a flexible plastic material so as to define a sealed pocket containing a dose of product.
  • the layer of semi-rigid material has a central pre-cut to guide and make subsequent breaking easier.
  • packaging machine for making up single-dose sealed packs with break opening is described by the patent WO2008/038074 and comprises a first and a second feeding device of a first tape of semi-rigid plastic material and of a second tape of flexible plastic material respectively.
  • the first and the second tapes are then superimposed on one another by means of superimposition means.
  • a scoring device of the first tape Upstream of the superimposition means is envisaged a scoring device of the first tape. More particularly, the scoring device is made up of two plates moving in direction of reciprocal approach/moving away, arranged on opposite sides of the first tape, having scoring elements suitable for cross scoring (i.e., at right angles to its extension) the first tape itself. To allow scoring the first tape, upstream of the scoring device, a pair of dandy rollers are provided suitable for permitting the temporary stop of the first tape between the pair of plates. Downstream of the superimposition means a first hot-sealing device is arranged suitable for the longitudinal sealing (i.e., parallel to their extension) of the two superimposed tapes, defining a sort of tube.
  • a second hot-sealing device Downstream of the first sealing device a second hot-sealing device is then arranged suitable for cross sealing the tapes to define along the tube one or more containment pockets of a respective dose of product.
  • product dosing means Between the first and the second sealing devices are placed product dosing means. More in particular, the dosing means remain placed between the two tapes following the longitudinal seal made by the first sealing device and dispense the dose of product inside the tube after the cross seal made by the second sealing device which practically speaking defines the bottom of the relative pocket.
  • the tapes continue to move forward towards the second sealing device, which seals the pocket containing the dose of product at the same time defining the bottom of the next pocket.
  • the sealed pockets made this way are then aligned with each other longitudinally.
  • the machine described in WO2008/038074 also envisages an additional sealing device, arranged downstream of the second sealing device suitable for making a cross seal wider than that made by the second device itself. Downstream of the additional sealing device is then provided a cutting device suitable for separating in succession the single-dose sealed cutting packs.
  • a drawback of this known packaging machine consists in its high complexity and, in particular, in the high complexity of the scoring device. The need to temporarily block the first tape to allow the plates to make the cut in fact calls for the use and the combination of a large number of components; this results in a high manufacturing cost, difficult maintenance and a high probability of malfunctions which could cause failure to make or incorrectly make the cut.
  • Another drawback of the packaging machine described above consists in the fact that the particular arrangement and realisation shape of the sealing devices and of the dosing means can contaminate the product contained in the single- dose pack, considerably reducing its storage period. In fact, it can occur that, while the second sealing device seals the top of the product containment pocket, the dosing means are still in the dispensing phase. At least a part of the product to be packed therefore comes into direct contact with the sealed edges of the containment pocket and, at least for some types of products (food, cosmetics or the like), the heat produced by the second sealing device causes the considerable deterioration of the product itself, with the concrete risk of contaminating the contents and negatively affecting its correct storage.
  • Another drawback consists in the complex making of the cross seals on the tapes, which requires two sealing devices arranged in series the one with the other.
  • the object of the present invention is to provide a packaging machine for making up single-dose packs with break opening, which has a scoring device that is much simpler in terms of manufacture and operation compared to that of the packaging machine described in WO2008/038074.
  • the object of the present invention is therefore to make a scoring device which is made up of just a small number of components, that is easy to service and adjust and which is reliable in terms of operation.
  • Another object of the present invention is to provide a packaging machine which allows performing sealing and dosing operations in a reliable and easy way, avoiding any risk of contamination of the product contained in a sealed pack.
  • Yet another object of the present invention is to considerably simplify the means that carry out the seals at right angles to the tapes with respect to the known packaging machine described above.
  • Another object still of the present invention is to provide a packaging machine of mechanical type, i.e., in which the various devices and means making it up are mechanically controlled.
  • the present packaging machine for making up single-dose packs with break opening, comprising: at least a first feeding device of a first tape of semi-rigid plastic material; - at least a second feeding device of a second tape of flexible plastic material; - at least a scoring device of said first tape arranged downstream of said first feeding device; superimposition means of said first tape on said second tape arranged downstream of said scoring device; at least a forming station of at least a single-dose pack, arranged downstream of said superimposition means, comprising: - at least a first and a second sealing device of said first tape with said second tape to define at least a sealed containment pocket and - at least a dosing station, positioned between said first and said second sealing device, for feeding a dose of product in said pocket; characterised by the fact that said scoring device is of the continuous type and comprises scoring means intended to be in constant and longitudinal contact with said first tape.

  • the pack 1 comprises a first layer 2 of semi-rigid plastic material and a second layer 3 of flexible plastic material, which is superimposed and sealed to the first layer 2 to define a sealed pocket 4 containing a dose of product P.
  • The, first and the second layer 2 and 3 have a substantially rectangular shape and the first layer 2, in its median area, has a first and a second cut 5a, 5b crossways to its extension, i.e., parallel to the shorter sides and at right angles to the longer sides.
  • the cuts 5a, 5b guide the breakage of the first layer 2, which occurs as a result of the folding of the first layer itself, to allow the product P to come out.

  • the machine 6 shown in the figure 3a comprises, besides the first and the second reels 12 and 13, also an auxiliary reel 12a, this too formed from the first tape 10. More in particular, when the first tape 10 that forms the first reel 12 is close to running out, its end section is connected to the initial section of the first tape 10 that forms the auxiliary reel 12a, in such a way that the machine 6 can quickly restart its operation without having to wait for the first reel 12 to be changed. Downstream of the first feeding device 8 a scoring device 14 is positioned of the first tape 10.
  • the scoring device 14 is of the substantially continuous type and comprises scoring means 15 suitable for contacting in a substantially constant and longitudinal way the first tape 10 and, therefore, defining along the first tape 10 at least a longitudinal and continuous cut 5a, 5b.
  • the scoring means 15 are composed of at least a cutting disc operating in rotation and defining a cutting surface suitable for longitudinally contacting (i.e., parallel to its extension) the first tape 10. In use, the position of the cutting disc 15 with respect to the first tape 10 is therefore fixed.
  • the scoring device 14 comprises adjustment means for adjusting the position of the cutting disc 15 with respect to the first tape 10.

  • the machine 6 Downstream of the scoring device 14, the machine 6 comprises superimposition means 16 for superimposing the first and the second tapes 10 and 1 1. More in particular, the superimposition means 16 are composed, as shown in figure 3, of a pair of parallel rollers, idle or motorised, having the side surfaces substantially in contact with each other and between which slide the tapes 10 and 1 1.
  • the rotation axis of the rollers 16 is substantially vertical and the tapes 10, 1 1 exiting from them lie on a substantially vertical plane and move along a substantially horizontal direction.
  • downstream of the superimposition means 16 are arranged forward movement means 17 for feeding the superimposed tapes 10 and 1 1 towards a forming station 18 on which are formed a succession of single-dose packs 1.
  • the forward movement means 17 are composed of a pair of motorised grip plates, parallel the one to the other and facing one another and positioned on opposite sides with respect to the tapes 10 and 1 1.
  • the grip plates 17 are movable in direction of reciprocal approach and moving away respectively to grip and release the tapes 10 and 1 1 and are movable, for a predefined stroke, along a forward direction substantially at right angles to the direction of reciprocal approach/moving away and substantially parallel to the tapes 10 and 1 1.
  • the direction of reciprocal approach/moving away of the grip plates 17 is shown in the illustration 5 with the reference number A, while the forward direction is indicated by the reference number B.

  • the further stroke of the grip plates 17 conveys the single-dose packs 1 thus formed and partially joined the one to the other to the cutting and unloading station 33.
  • the second cutting means 34, 35, 36 separate the single-dose packs 1 completely the one from the other, the single-dose packs 1 falling by gravity resting on the supporting element 38, 39.
  • the operation of the second cutting means 34, 35, 36 occurs at substantially the same time as that of the sealing devices 19 and 20 and of the nozzles 31 on the sections upstream of the tapes 10 and 1 1.
  • the plates making up the first and the second sealing devices 19 and 20, as well as those supporting the second cutting means 35, 36 are therefore mechanically connected the one to the other and move substantially in synchronism.
  • the packaging machine according to the invention allows achieving the preset objects.
  • the machine according to the invention allows, with respect to the state of the art, considerably simplifying the scoring phase of the semi-rigid material and, at the same time, carrying out the sealing and dosing operations in a practical, easy and functional way, ensuring the perfect preservation of the product contained in the packs thus obtained and avoiding any risk of contamination.
