Definitions

  • the present invention relates to a vertical machine for packaging in bags a product with substantially fluid behaviour.
  • the speed of the machine is greatly limited by the need to wait for the granular product to drop completely, which product is supplied in an inconsistent manner by an upper hopper.
  • the general object of the present invention is, inter alia, to prevent the aforesaid drawbacks by providing a packaging machine for packaging a product into bags at high frequency owing to a special batching device.
  • the device generates constant and repeatable high volumes of product to be discharged at high frequency inside the bags of the packaging machine in a synchronised and constant manner.
  • a vertical machine for packaging into bags a product with substantially fluid behaviour, comprising a unit supplying product to a batching unit underneath to discharge batches of product into a forming pipe of a unit for packaging into bags
  • the batching unit comprises two cups supported and driven to be aligned alternatively on the forming pipe, each cup comprising below a discharge gate valve that is driven for discharging vertically into the aligned forming pipe, above the cups there being a levelling cone supplied by the product supplying unit and which is movable for being aligned on command alternatively with a cup to fill the cup with product, each cup defining an internal volume that is substantially equal to the volume of product per single bag and, along the vertical discharge direction, the cups each having both a surface and a perimeter of the cross section that remain constant, or at most grow, from top to bottom.
  • figure 1 shows schematically a vertical packaging machine, indicated generally by 10, made according to the invention.
  • the machine 10 comprises above a supplying unit 11, that discharges the product (through a flexible pipe 12) into a batching device 13 that in turn conveys the product into a forming pipe 14 of a known packaging unit 15.
  • a web of film 16 is supplied which forms into a longitudinally welded pipe 17 and which after each filling is welded transversely in a known welding unit 35 that comprises special transverse jaws (not shown) for forming the full and sealed bags.
  • the packaging and welding units of the packaging unit are in themselves known and easily imaginable by those skilled in the art and will not therefore be disclosed in detail.
  • the supplying unit advantageously comprises a hopper.
  • the supplying hopper is also easily imaginable by those skilled in the art. It has a cylindrical shape that ends below with a cone frustum and has the simple function of containing and constantly mixing the product, in addition to acting as a storage unit kept at a roughly constant level in function of probes that will interact with the hopper loading system.
  • the batching unit 13 comprises a fixed frame 18 on which a movable carriage 19 is mounted that runs horizontally owing to linear sliding blocks 21.
  • a motor 20 can move the movable carriage 19 along the sliding blocks 21 with alternating movement by means of a screw coupling 22.
  • the carriage 19 supports two vertical batching cups 23, 24 placed adjacently in the movement direction of the carriage to move alternatively in the vertical direction of the forming pipe 14.
  • Each cup 23, 24 has a bottom closed by a respective lock 25, 26.
  • the two locks 25, 26 are slideable independently of one another by means of a respective pneumatic actuator 30, 31 to open upon command the bottom of the respective cup and discharge the contents thereof into the forming pipe 14 underneath.
  • the perimeter of the lower outlet of the cup substantially follows the internal upper perimeter of the forming pipe to become juxtaposed thereto.
  • a single conveying pipe or levelling cone 27 is present that is supported on the movable carriage 19 by means of a slide 28 that is moved alternatively between the two cups by means of an actuator 29 (advantageously a pneumatic cylinder).
  • the conveying pipe is supplied above with product through the flexible pipe 12.
  • both the surface and the perimeter of the cross section of the cups remain constant, or at most grow, from top to bottom, in such a way as not to cause fluidodynamic acceleration in the product in transit.
  • the shape of the cup pre-form in fact enables the product not to become decomposed during the drop and the shape thereof not to be modified, thus adapting better to the section of the forming pipe during the descent but above all enables queues or dragging of product between one discharge and another not to be created.
  • the volume contained in each cup substantially has to be the volume of the product to be introduced into a single package.
  • the product supplied for packaging has substantially fluid behaviour; it is typically to be equated with powders with granulometrically constant and morphologically regular features, such as to enable the product to behave like a fluid through the effect of gravity.
  • the treated product must in general be non-abrasive, dry and non-adhesive due to the mechanical or electrostatic effects.
  • the product to be batched flows by dropping through the levelling cone 27 into the aligned cup, stopping the flow once the cup has been completely filled. A uniform and compact column of product is thus formed as far as the loading hopper.
  • the other cup which is coaxial with the forming pipe 14, discharges the product with the opening movement of the respective lock.
  • the lock is closed again after a preset time T has elapsed that ensures complete evacuation of the product from the cup.
  • the actuator 20 is commanded to move the full cup to a position that is coaxial with the forming pipe 14 whilst the levelling cone 27 is positioned above the other cup by means of the movement of the slide 28 controlled by the actuator 29.
  • the cup in the position that was coaxial with the forming pipe is thus ready to be unloaded, with the corresponding opening movement of the lock thereof.
  • the cycle may start again from the beginning with the opposite movement of the movable carriage 19 and so on.
  • the operating logic of the movements is not sequential but takes account only of overriding some simultaneous events: the movement of the movable carriage 19 occurs only after time T has elapsed for the cup that is coaxial with the forming pipe and the certain reclosure of the lock 25 or 26 has been ascertained (advantageously by means of a known suitable sensor, which is not shown); the movement of the slide 28 occurs only if the cups are both shut and if in the meantime a lock opens, which means that the opposite cup has been discharged; the movement of one or the other lock occurs alternatively in function of the position of the movable carriage 19 (thus in function of which cup is coaxial with the forming pipe).
  • the device is supplied by a flexible pipe with a continuous hydrostatic head of product that transfers the product from the hopper to the batching cups in a constant manner to ensure at the same time a high flow and uniform compactness of product in the cup, thus ensuring repeatability and thus batching accuracy.
  • the vertical packaging part may be of any type that is known and is easily imaginable by those skilled in the art which has been chosen to make any desired type of package.
