Definitions

  • This invention relates to an apparatus for moulding containers, in particular bottles, made of thermoplastic material, in particular PET, by blowing or blowing and stretching. More specifically, this invention relates to a blow-moulding apparatus designed to make bottles of different sizes.
  • the bottles are made in moulds comprising two half -moulds hinged to each other along a defined axis and mobile towards and away from each other about this axis, and a bottom mould, also known as "base-mould", mobile vertically along an axis parallel to the axis of the two half-moulds between a lowered position and a raised operating position where it engages the two half- moulds.
  • a bottom mould also known as "base-mould”
  • base-mould mobile vertically along an axis parallel to the axis of the two half-moulds between a lowered position and a raised operating position where it engages the two half- moulds.
  • Each mould component is internally shaped in such a way that when the three components are engaged with each other, they form a cavity whose shape and volume correspond to the shape and volume of the bottle to be made with the mould.
  • the base-mould is supported by a rod having, at its top end, a supporting surface for the base-mould and, at its bottom end, a cam follower wheel.
  • the wheel is designed to engage a cam that imparts the upward or downward vertical movement to the rod and hence to the supporting surface.
  • the base supporting surface is moved selectively to the lowered or the raised position.
  • the base-mould guide rod cannot be used to vary this height because it must engage the cam and must therefore remain at a fixed height.
  • the height reached by the base-mould is varied using spacing elements or spacers interposed between the base-mould and the surface that supports it on the guide rod.
  • the spacers vary in size according to the height of the bottle to be made and are used to vary the maximum height reached by the base- mould when it moves to the raised position.
  • the fact that the base-mould and the element that supports the base-mould i.e. the element which defines an upper limit for the stroke of the base-mould
  • the element that defines an upper limit for the stroke of the base-mould are arranged at an adjustable distance (in order to accommodate moulds for blowing containers of different sizes) makes the setting of the blowing machine time consuming and scarcely precise, because each base-mould must be adjusted singularly, with respect to its distance form the corresponding support element.
  • This invention therefore has for an aim to overcome the above mentioned disadvantages by providing a blow-moulding apparatus that enables the size of the bottles being made to be changed quickly and effectively without having to use different components for each different size.
  • this aim is achieved by a blow-moulding apparatus, in particular a blow mould, comprising the technical features set out in one or more of the appended claims.
  • the invention concerns an apparatus for blow-moulding parisons to make plastic containers (such as bottles), comprising:
  • a carrousel that turns about an axis and is equipped with at least a mould having two half -moulds mobile towards and away from each other and a base- mould mobile vertically relative to the two half-moulds between a lowered non- operating position and a raised position where it engages the two half-moulds, the base-mould and the two half-moulds forming an internal cavity when engaged with each other;
  • a base-block for supporting the base-mould; - means for guiding the base-mould, designed to interact with a cam to move the base-mould between the lowered position and the raised position, the base-mould being slidably mounted on the base-block in such a way as to move, relative to the two half-moulds, between the lowered position and the raised position, wherein the base-block is configured to limit upwardly a stroke of the base-mould, to define said raised position.
  • the apparatus comprises:
  • said adjusting means defining at least one predetermined position for the base- block relative to the supporting means, wherein said means for guiding the base-mould are arranged at a fixed distance from the base-mould.
  • the means for guiding the base-mould are rigidly connected to the base-mould. This makes the machine particularly reliable and robust and, at the same time, allows a rapid adaptation of the machine to the blowing of containers of different sizes in moulds of different sizes.
  • he apparatus comprises means for calibrating (i.e. adjusting the position of) the cam; said calibrating means are configured to adjust the position of the cam according to the distance between the base-block and the carrousel.
  • Figure 2 illustrates the apparatus of Figure 1 in a schematic perspective view from a different angle
  • FIG. 3 is a schematic perspective view illustrating an enlarged detail of the blow-moulding apparatus according to the invention in a first operating configuration
  • Figure 4 shows the detail of Figure 3, with some parts cut away to better illustrate others and with some parts exploded;
  • Figure 5 illustrates the detail of Figure 3 in a schematic perspective view from a different angle
  • FIG. 6 shows the detail of Figure 5, with some parts cut away to better illustrate others and with some parts exploded;
  • FIG 7 is a schematic perspective view illustrating an enlarged detail of the blow-moulding apparatus according to the invention.
  • FIG. 8 is a schematic perspective view from a different angle illustrating the detail of Figure 3 in a second operating configuration.
  • the numeral 1 denotes in its entirety an apparatus for blow-moulding parisons to make plastic containers, and in particular, bottles.

  • blow -moulding apparatus may also be of the linear type.
  • the blow-moulding apparatus 1 comprises a carrousel 2 that turns about an axis X.
  • the carrousel 2 comprises a plurality of moulds 3.
  • the carrousel 2 is illustrated schematically and comprises only one mould 3.
  • the carrousel 2 turns between a parison infeed station, where a parison is placed inside a respective mould 3, and bottle outfeed station, where the bottle made by blow-moulding the parison in the mould 3 is extracted from the mould 3 and transferred to other stations downstream.
  • the mould 3 comprises two half-moulds, namely a first half -mould 4 and a second half-mould 5, hinged to each other and rotatable about a vertical axis Y, and a bottom mould 6, or base-mould.
  • the two half-moulds 4, 5 are free to rotate about the axis Y towards and away from each other.
  • the base-mould 6 is mobile vertically relative to the two half-moulds 4, 5 between a lowered non-operating position and a raised position where it engages the two half-moulds 4, 5.
  • the two half-moulds 4, 5 and the base-mould 6 can therefore move between an open position (half-moulds 4, 5 away from each other and base-mould 6 lowered) where the parison can initially be fed in and the finished bottle extracted at the end, and a closed, blow-moulding position (half-moulds 4, 5 clamped shut and base-mould raised and engaged with the half -moulds) during which a fluid is blown into the parison under pressure to make a bottle.
  • the base-mould 6 comprises an upper portion 6a in the form of a substantially annular, or petaloid, cavity shaped like the bottom of the bottle, and a rod 6b supporting the upper portion 6a.
  • Each of the two half-moulds 4, 5 has a respective internal cavity 4a, 5a forming half of the central portion of the bottle, shown in Figure 1.
  • the base-mould 6 is connected to the carrousel 2 by means of a support 7, shown in detail in Figures 1, 2, 3, 4, 5 and 6.
  • the support 7 comprises an upper plate 8 fastened to the carrousel 2 by four screws 9 (of which only two are shown Figure 1) and two parallel vertical rods, namely a first rod 11 and a second rod 12.
  • the first rod 11 and the second rod 12 are circular in cross section, are connected to the plate 8 and have a predetermined spacing D between them.
  • the rod 11 has a plurality notches 13 in the form of grooves cut in the rod 11 itself and whose function is described in detail below.
  • the apparatus 1 comprises a base-block 14 for supporting the base-mould and in the form of a slider that runs along the rods 11, 12.
  • the first rod 11 and the second rod 12 constitute means 10 for supporting the base-block 14.
  • the notches 13 constitute means 102 for adjusting the base-block 14 relative to the supporting means 10.
  • the base-block 14 is moved along the rods 11, 12 to a predetermined required position corresponding to one of the notches 13 on the vertical rod 11.
  • the base-block 14 comprises a first through hole 15 in which a screw 16 with a bush 17 round the outside of it is inserted.
  • the screw 16 and the bush 17 constitute means 103 for fastening the base- block 14 to the supporting means 10.
  • the profile of the bush 17 is such that it will adapt to any of the above mentioned notches 13: that way, once the base-block 14 has been moved to the required height, the base-block 14 is fixed axially in place relative to the rods 11, 12 by the screw and bush assembly 16, 17, which engages a corresponding notch
  • the base-block 14 is fastened stably to the rods 11, 12 by three screws 18, illustrated in Figure 4.
  • the rod 6b that supports the base-mould 6 is connected to the base-block 14 by an interposed slide 19 fixed to the base-block 14 itself.
  • the base-mould 6 can therefore slide axially relative to the base-block 14.
  • the base-mould 6 is free to move along the slide 19 between the aforementioned lowered position and the aforementioned raised position of engagement with the half-moulds 4, 5.
  • the height reached by the base-mould 6 in the raised position depends on the notch 13 which the base-block 14 is fastened to, as described in more detail below.
  • the blow-moulding apparatus 1 comprises a circular segment 20 adjacent the carrousel 2. On the inside wall of it facing the carrousel 2 the circular segment 20 is equipped with a track 21 forming a cam 22.
  • the rod 6b that supports the base-mould 6 comprises a pair of wheels 23 designed to engage the cam 22, in such a way as to enable the base-mould 6 to move vertically between the above mentioned lowered position and the above mentioned raised position as the wheels 23 run along the cam 22.
  • the apparatus also comprises a pair of springs 100 interposed between the base-block 14 and the base-mould 6.

  • the cam 22 is mounted on a pair of vertical telescopic rods, labelled 24 and 25.
  • the telescopic rods 24, 25 can move vertically up or down by means of a kinematic chain 26.
  • Each telescopic rod 24, 25 is composed of two portions:
  • Each outside portion 24b, 25b is coupled to the respective inside portion 24a, 25a by screwing.
  • each inside portion 24a, 25a is threaded and each outside portion 24b, 25b is screwed onto the respective inside portion 24a, 25a. In that way, turning the inside portion 24a, 25a causes the outside portion
  • each telescopic rod 24, 25 has a sprocket wheel 27 at its bottom end.
  • the kinematic chain 26 comprises: a shaft 28 with a sprocket wheel 29 at its bottom end; a bevel gear pair 30 associated with the shaft 28, for moving the latter and able to be operated by hand using a crank lever 31; and a sprocket wheel 32 for each telescopic rod 24, 25.
  • the bevel gear pair 30 may be operated automatically.
  • the kinematic chain is not provided and the telescopic rods, and hence the cam, can be lifted and lowered by hand.
