Definitions

  • the present invention refers to the packaging of various types of articles into flexible plastic bags formed starting from a continuous web created by two superimposed flat layers mutually joined along at least one longitudinal edge.
  • plastic material in referring to such webs is not intended to be limiting, in that it intends films of materials such as polyethylene and the like, but also coupled paper/plastic films, poly-coated paper or other polylaminates , provided that they are at least partially electrically insulating, for reasons that will be clarified below.
  • the object of the present invention is that of providing a simple, yet efficient and functional solution for detecting possible anomalous situations for which, as was stated, no visual monitoring or manual interruption of the operation of the machine are required .
  • each abutment member and the corresponding movable clamp member constitute also a detector of the presence/absence of the corresponding edge of the web length in the above-said juxtaposed closed position, said detector being operationally connected to a control unit.
  • each abutment member and the corresponding movable clamp member define the contacts of an electrical switch: the presence of the edge of the web length, which as was stated is of an electrically insulating material, maintains such switch open. On the contrary, absence of the web length edge causes closure of the switch and consequently the intervention of the electronic control unit, which envisions the automatic stopping of the operation of the machine.
  • figure 1 is a schematic view in side elevation showing the fill-in station of a packaging machine according to the invention in a first operative position, and in which the relative electrical connections to the control unit are indicated diagrammatically, and
  • figures 2 and 3 are views analogous to figure 1 that represent the fill-in station in a second operative condition and in two different situations, respectively .
  • the fill-in station of the packaging machine is of the type generally known from the previously cited patent EP-0926069B1 , and for that reason will not be described in detail.
  • the fill-in station of the packaging machine comprises two operating heads 1, 2 through which a continuous web of flexible heat-sealable material is supplied, typically plastic material, in all cases electrically insulating.
  • the web can be, for example constituted by a flattened tubular film formed by two superimposed layers mutually joined along at least one lateral edge.
  • the fill-in station is provided with heat-sealing and cutting means, known and for simplicity not illustrated, by means of which sacks or bags (S) are formed periodically from the continuous web supplied intermittently to the fill-in station, first closed below, then filled from above with articles to be packaged, and finally sealed above after filling.
  • S sacks or bags
  • each bag S open above is grasped and held in correspondence to its upper edges by the two heads 1, 2, maintained reciprocally juxtaposed in the condition represented in figure 1. Then the two heads 1, 2 are reciprocally spaced apart transversally, for example moving head 2 with respect to head 1 as represented in figures 2 and 3, so to spread apart the edges of the bag S and allow introduction of articles.
  • each of the heads 1, 2 is provided with respective grasping means including a lower abutment member 3; 4 and an upper clamp 5, 6 movable vertically with respect to the corresponding lower abutment member 3, 4 between the raised open position, represented in figure 1, and the lowered closed position, represented in figures 2 and 3.
  • the abutments 3, 4 are conveniently constituted by adhesive pads apt to adhere to the edges of the bag S in the reciprocally juxtaposed condition of the two heads 1, 2 to allow then pinching of the relative clamp member 5, 6 following their movement from the raised to the lowered position, and the successive spreading apart by the reciprocal separation of the heads 1 and 2.
  • each abutment member 3, 4 with the respective movable clamp member 5, 6 of each head 1, 2 defines a detector of the presence/absence of the corresponding edge of the bag S.
  • such detector is electrical and is more precisely constituted by a switch, the fixed contact of which is constituted by abutment member 3, 4 (that is, by an electrically conductive part thereof) and the movable contact of which is constituted by the clamp member 5, 6 (that is, by an electrically conductive part thereof) .
  • the contacts 3, 5 and 4, 6 of each switch are connected electrically to the respective inputs of an electronic control unit 7 designed to control the operation of the machine.
  • figure 2 illustrates an anomalous situation in which one of the edges, in this case the one corresponding to head 1, was not properly retained between the abutment 3 and the clamp 5, that is, for some reason it was disengaged.
  • the switch constituted by the contacts associated with the abutment 3 and the clamp 5 close, causing the intervention of the electronic control unit 7.
  • control unit 7 The opening or closing of one and/or the other switch is detected by the control unit 7, which is then able to discriminate between situations of correct and anomalous operation.
  • the detector of the presence/absence of the edges of the bag S associated with the heads 1, 2 may be constituted by different sensors, instead of electrical switches, also of more sophisticated types, apt to detect for example field variations or other electrical characteristics according to whether the edges of the bag S are correctly retained between the abutments 3, 4 and the relative clamps 5, 6.

Abstract

L'invention porte sur une machine pour l'emballage d'articles dans des sacs en plastique souples, une bande continue formée par deux couches superposées plates étant fournie à un poste de remplissage (1, 2) et la bande étant coupée transversalement pour former des longueurs de bande de la longueur désirée. Les bords supérieurs des longueurs de bande sont saisis et écartés pour introduire des articles, tandis que la présence/l'absence de tels bords est respectivement détectée simultanément pour permettre ou empêcher automatiquement le fonctionnement de la machine.
