Definitions

  • the present invention relates to a device for spacing at a predefined interval containers generally made of plastic, provided with an element for separating and braking the containers.
  • the present invention falls within the sector of devices for conveying containers, in particular containers made of plastic or PET, and acts as a connection between successive workstations.
  • Containers made of plastic or PET, more specifically bottles, must undergo a sequence of processing operations such as blowing, rinsing, filling and labelling, for each of which a workstation operating at a predefined interval and speed is provided.
  • the conveying device as a whole must therefore ensure, in addition to transfer of the containers from one station to the other, also adaptation of the feeding movement of the containers to the operating parameters of the machine downstream, in particular using the same interval and synchronizing the speed.
  • This type of conveyor which is generally operated by air or by chains, is able to transfer the containers in a compact row, keeping them in a vertical position and suspended by their necks, but is unable to space the containers so as to adapt them to the next workstation.
  • Chain conveyors suitable for this purpose are known, on which the containers rest with their bottom, synchronized with the workstation downstream, and which pick up the containers leaving the overhead conveyor and transfer them to a star conveyor.
  • the abovementioned containers are channelled between two screw feeders which space them by a distance equal to the operating step of the star conveyor and the workstation.
  • the containers which are suspended by their necks and arranged in a row, reach the exit section of an overhead conveyor where they are received by a pair of guides and are introduced by the latter into a star conveyor which spaces them at a suitable interval.
  • the star conveyor has two disks which are arranged above one another and coaxial and the external circumference of which, during rotation, comes into contact with the linear trajectory of the containers leaving the overhead conveyor.
  • the spacing of the containers is performed by means of recesses provided at a suitable angular interval in one of the two disks and formed so as to engage with and move the containers by means of their necks.
  • the second disk allows the containers to be stabilized, preventing any oscillating movements.
  • Such a device although simplifying the structure and accelerating the process, still has some drawbacks.
  • the two guides are necessary for supporting the containers along the portion between the exit section of the overhead conveyor and the section for entry into the star conveyor.
  • the object of the present invention is that of eliminating the abovementioned drawbacks and providing a device for spacing containers at a predefined interval, provided with an element able to divide and brake the containers so as to allow the star conveyor to engage correctly with the neck. Said objects are fully achieved by the device for spacing at a predefined interval containers generally made of plastic, according to the present invention, provided with an element for separating and braking the awaiting containers, which is characterized by the contents of the claims indicated below.
  • the device in question transfers directly to the star conveyor the containers leaving the overhead conveyor, with the aid of a separating and braking element which characterizes it.
  • This element for separating and braking the awaiting containers is formed substantially as a star conveyor comprising at least one disk with generally semi- cylindrical recesses for accompanying and separating the containers.
  • the insertion of this characterizing element may be performed at different distances from the star conveyor so as to allow the seating of containers with variable dimensions.
  • 1 denotes a container which is passing through the device according to the present invention, supplied by an overhead conveyor 2 along which the container 1 travels, suspended by its neck 3, following a substantially rectilinear trajectory 1 1.
  • the overhead conveyor 2 is of the air-operated type and transfers the containers 1, keeping them vertical and in a compact row, namely not separate from each other.
  • the containers 1 consist of bottles made of plastic, more particularly PET, which have the neck 3 in the vicinity of the mouth.
  • the containers 1 must follow a sequence of processing steps, such as blowing, rinsing, filling and labelling which result in their passing through stations with different operating parameters. Therefore the containers 1 , before entering into the workstation in question, must undergo spacing so as to have the same interval as the machine downstream.
  • This spacing is performed by means of a star conveyor 4 which engages with and moves along a circular trajectory 12 the containers leaving the overhead conveyor 2, supporting the necks 3 of the containers which are thus conveyed in the suspended condition, without resting with their bottoms on a support surface.
  • the star conveyor 4 has a substantially circular shape and comprises at least one disk in which recesses are formed in a known configuration not shown in the figures. Transfer of the containers 1 from the overhead conveyor 2 to the star conveyor 4 occurs directly, without the use of guides, which are required, on the other hand, in the device according to Italian Patent No. 1260380 mentioned above.
  • the element 5 is also able to brake the advancing movement of the row of containers 1 , thus ensuring that the star conveyor 4 engages more easily and reliably with a single container per recess.
  • the separating and braking element 5 is formed substantially as a star conveyor, mounted idle and rotating about an axis 6, so that the external circular trajectory 13 is substantially tangential to the rectilinear trajectory 1 1 and to the circular trajectory 12 in the vicinity of their point of contact.
  • the element 5 comprises an upper disk 7 in which recesses 8 with a substantially semi-cylindrical shape alternating with dividing portions 9 are formed.
  • the recesses 8 receive a container and transfer it to the star conveyor 4 separated from the other containers by means of the dividing portion 9.
  • This dividing portion 9 also performs the function of braking the feeding movement of the compact row of containers 1.
  • the separating and braking element 5 is provided with a lower disk 10 which is coaxial with the upper disk 7 and comes into contact with the containers 1 along a portion different from that of the upper disk 7 so as to accompany and stabilize the container.
  • the separating and braking element 5 may be mounted so that its distance from the star conveyor 4 is adjustable according to the dimensions of the containers 1.
  • This adjusting movement may be performed via adjusting means not shown, comprising means for locking the abovementioned axis in the chosen position and an eyelet, in which the axis 6 of rotation of the separating and braking element 5 is introduced free to slide in the longitudinal direction with respect to the eyelet itself.
  • the adjustment of the position of the axis 6 of the separating and braking element 5 may envisage some main positions for the containers which are most frequently used.

Abstract

L'invention concerne un dispositif permettant d'espacer à un intervalle prédéfini des récipients (I) généralement formés de plastique, amenés par un transporteur (2) surélevé. Les récipients se déplacent le long de ce dernier en rangée compacte, en suivant une trajectoire (11) suspendues par leurs cols (3) saillants puis entrent dans un transporteur (4) en étoile conçu pour les espacer à un intervalle prédéfini, et dans lequel elles suivent un trajectoire (12) circulaire suspendues par leur col (3). Un élément (5) servant à séparer et à freiner les récipients est installé entre le transporteur (2) surélevé et le transporteur (4) en étoile.
