Definitions

  • This invention relates to a volumetric dosing apparatus for pasty material, namely for chopped meat and the like, for filling a packing line by thermoforming, of the type comprising at least an adjustable dosing chamber, having a known capacity, which can be automatically and cyclically filled and emptied to form portions having an identical volume and to deposit them in thermoformed cavities which are transferred on a travelling band under said chamber.
  • Patent WO 9014578 in which a machine is disclosed which includes a dosing chamber with an inlet and an outlet at one of its ends. Said dosing chamber is provided in its interior with a distributor to alternatively communicate said chamber with said inlet and with said outlet and a plunger which can be freely moved by the effect of the pressure exerted by a pasty material introduced in the dosing chamber by a feeder, a pump or the like, through said inlet and said distributor in inlet position. Said plunger free run goes from a first position to a second position which is predetermined by means of an accurately adjustable stop using a worm system which delimits the volume to be dosed.
  • said plunger is driven in the opposite direction by means of compressed air, being forced to come back to said first position, moving the dosed volume of pasty material through said distributor in position of communication with said outlet, from which it can be collected in a container or stuffed.
  • Said apparatus has pneumatic means which raise the whole dosing chamber in order to allow the access to the alternating distributor for its withdrawal, periodical cleaning and/or inspection.
  • Above apparatus is fully effective as for identical volume portions forming, but, however, it has the drawback that it expels the portions in an horizontal direction unsuitable for filling thermoformed cavities arranged on a continuous travelling band.
  • an object of this invention is to provide with a volumetric dosing apparatus for pasty material for filling a packing line by thermoforming, provided with multiple outlet openings for the dosed portions situated uprightly downwards, mounted on a support which can be situated above a travelling band, so that said outlet openings are facing each other and close to thermoformed cavities arranged on it.
  • Another object of the invention is to provide with an apparatus of the type referred to with means of access to the distributing mechanism, simple, easy to handle and safe for the worker.
  • Said valve body in cooperation with corresponding ducts communicated with said housing, is capable of conducting a pasty material introduced by an external feeder through an inlet arranged in axial position inwardly the dosing chambers and, successively and alternatively, to lead the pasty material from the interior of the dosing chambers, pushed by pneumatic means, up to other as many openings situated at the lower part of said housing of the valve body, aligned with said chambers.
  • the apparatus of the invention has available a combined system formed by plungers for withdrawing the portions of the volume from within the chambers, which correspond to the so-called doses, and pushers to finish to fully empty the lengths within the valve body.
  • said pushers are provided with stems which protrude at the top end of the dosing chambers while the plungers are provided with central holes by means of which they can freely slide along a portion of said stems.
  • the top ends of all these stems are fixed on a plate provided with a slide which is sliding inserted in a second stem ended at both ends by stops.
  • a pneumatic cylinder moves a pneumatic clamp which can grasp said plate to force, through the respective stems, the pushers to individually carry out said travel within the valve body and release said plate to allow that said pushers, together with their corresponding plungers, carry out their joint travel within their related dosing chambers, moved by the pressure of the pasty material during the filling, and impelled by means of compressed air injected by the top end of said chambers during the emptying operation.
  • said plate When the pushers, together with the corresponding plungers start the portion of travel within the dosing chambers, said plate, freed of said clamp, contacts the top stop of the second stem pulling it along in its travel until said lower stop contacts a block situated in a predetermined position, accurately adjustable by means of a worm driven by an electric motor.
  • valve body housing and its corresponding ducts and openings is carried out by means of a block fixed overhanging from a side cabinet, adjustable in height and provided with travelling feet on which block a base plate is hinged which bears said dosing chambers with their related mechanisms, covered by a housing.
  • Said block incorporates sealing means for said plate in working position, as well as a cover likewise at one end likewise hinged and provided with sealing means.
  • Said side cabinet incorporates a pneumatic cylinder for driving the valve body, as well as the electric and pneumatic circuits with their related control devices.
  • the apparatus of this invention can be situated so that its dosing head remains above a travelling band, with said outlet openings facing each other and close to thermoformed cavities arranged on said band, for their filling, the cycles forming the dosed portions being synchronized with stop and forward movement cycles of said travelling band.
  • a block associated to dosing chambers 4 provided with joining means 47 to be fastened overhanging on a side housing 41 mounted on a pair of feet 42, provided with wheels 43, capable to keep the assembly in stable equilibrium leaving a large space between said feet 42 and the outlet mouths of the outlet ducts 2, said housing incorporating said cylinder 19 for driving the valve body 7, electric circuitry and fluid dynamic elements (not shown) with corresponding control elements thereof and means 44, 45 to adjust in height the position of said block 9 so that it can be positioned above and close to containers A formed on a self-conveyed band B , which is an integral part of the packing line, for example by thermoforming.
  • Said means for adjusting in height the position of said block 9 consist in fastening elements 44 integral with a first portion 41a, associated to said at least one foot 42, of the housing 41, in cooperation with oblong holes 45 formed on a second portion 41b, bearing said block 9, of the housing 41, and in that it includes a protecting cover 46 of the dosing chambers 4 and mechanisms associated with them 21-35.

  • the first position 5A of the stem 5 is delimited by a protrusion 28 formed by the slightly smaller diameter of the passageway duct 3 communicated with the housing 6.
  • the apparatus includes a detector 48 of end of stroke of said joint run of the stem 5 and the pusher 20, which releases a signal to stop the entrance of pasty material M through the inlet duct 1, to move the valve body 7 from the first position 7A to the second position 7B and activate the entrance of the fluid under pressure F by the second end 4b of the dosing chamber 4.
  • Fig. 6 illustrates a step in which the stem 5, together with the pusher 20 move within the chamber 4 under the effect of a pressure exerted by a pasty material introduced from the inlet duct 1 through the valve body 7 at the position 7A.
  • Said pasty material is directly in contact with the pusher 20 which pulls along the stem 5 and the first stem 22 which is integral with the plate 24 bearing the slide 25 which contracts the stop 32 pulling along the second stem 23.
  • the second stem 23 slides within a hole of a block 29, fixed at a predetermined position by means of a worm 30 driven by a motor 31, until the stop 33 of said stem 23 contacts said block 29 (Fig. 7), delimiting the second position 5B of the plunger 5.
  • the entrance of pasty material through the inlet duct 1 stops and the valve body 7 rotates within its housing 6 to adopt the second position 7A.
  • a fluid under pressure preferably air
  • the injection of a fluid under pressure starts, by the second end 4b of the chamber 4, so that the stem 5 moves in direction to the first end 4a pulling along with it the pusher 20 and the first 22 and second 23 stems until said stem 5 stops against the protrusion 28 at the first end 4a of the chamber 4, which delimits the first position 5A of the stem 5 (Fig. 8).
  • the volume delimited by the internal diameter of the chamber 4 and the distance between said first 5A and second 5B positions constitutes the accurate dose of the portions to be packed. Said distance is determined by the position of the block 29, and coincides with a second portion 23b of the second stem 23 which slides within a hole of said block.
