Definitions

  • This invention relates to an integrated bale-forming and wrapping machine which comprises a bale pressing mechanism which is operative to form a mown or cut agricultural crop, such as grass, into a cylindrical bale, and a bale wrapping mechanism which is operative, after formation of the cylindrical bale, to apply stretch film wrapping to the cylindrical surface and to the two planar end faces of the bale .
  • bale-press of the "fixed chamber", or of the "variable chamber” type, in which a mown or cut crop e.g. grass or straw lying on the ground is picked up, and then formed into a cylindrical bale (a so-called “round bale” or “big bale") within a pressing chamber defined within the bale press.
  • a mown or cut crop e.g. grass or straw lying on the ground
  • a cylindrical bale a so-called “round bale” or “big bale”
  • twine or cord, or netting to the cylindrical surface only of the bale, prior to rearward discharge of the bale onto the ground.
  • the rearward discharge of the bale usually takes place by upward pivoting of a rear enclosure wall of the bale press, which then allows the bale to be discharged from the pressing chamber and via an outlet defined by the upward pivoting of the rear wall.
  • Stretch film wrapping of other agricultural crop material, and particularly long stem material such as straw or hay also can be carried out in order to exclude the baled material from contact with rain and air born moisture.
  • Bale wrappers generally fall into two separate categories, one being of the rotating table or turntable type in which film is withdrawn from d static film dispenser reel and is applied to all of the external surfaces of the bale as a result of combined rotation of the bale about two perpendicular axes simultaneously i.e. 1 ) rotation of the bale directly about its longitudinal axis (which is usually horizontal or near horizontal) by engagement of drive rollers and / or a belt with the underside of the bale; and 2) rotation of the bale about an upright axis (usually vertical or near vertical) by rotation of the entire table or platform on which it is supported.
  • bale wrapper is an "orbiting" or satellite type of film dispenser reel, in which the bale is rotated about its longitudinal axis, but the rotation of the bale about the vertical axis is replaced by the technical equivalent of causing the film reel to orbit around the bale in a substantially horizontal plane.
  • bale press fixed and variable chamber
  • bale wrapper two types of bale wrapper
  • bale wrapping mechanism coupled with the rear end of a standard design of bale press, such mechanism receiving the bale after it has been formed and then rearwardly discharged from the pressing chamber.
  • the bale wrapping mechanism therefore forms a rearward extension of the bale press, and receives the bale directly from the press, rather than by picking it up off the ground after it has been discharged onto the ground by the press in existing two machine operation.
  • bale press examples include machines of the type known from EPO 110110 (Manuli) and German OS 2614154 (Claas), as well as DE 4120733 (John Deere).
  • the invention seeks to provide a combined cylindrical bale-forming and wrapping machine, in which the wrapping of the bale can take place within the general confines of the bale press e.g. preferably to wrap the bale at the same general location in the bale press at which it has been formed, so as to provide a combined bale-forming and wrapping machine which is of generally the same length as existing designs of bale press .
  • This invention provides integration of a bale-wrapping mechanism within the region of the bale pressing chamber, and up to now this has not been thought to be possible in view of inevitable mechanical complexity of integrating such mechanism into the machine to carry out the quite different function of bale wrapping, compared with the mechanism employed to carry out formation of the cylindrical bale.

Abstract

La présente invention concerne une machine combinée (10) servant à presser les balles et à les emballer. Elle est en mesure de: (a) ramasser une récolte sur le sol; (b) donner à cette récolte la forme d'une balle cylindrique (15); (c) placer un film d'emballage étirable sur la surface extérieure de la balle, et (d) évacuer la balle emballée de la machine. Cette machine comprend: un châssis (11), un ramasseur (14), un support (16) monté sur le châssis (11) et conçu pour porter un rouleau (17) de film plastique étirable; un compartiment de compression qui 1) comprend des dispositifs de prise supérieurs et inférieurs de forme généralement arquée (18, 19); 2) le dispositif de prise inférieur (19) comprend une série de rouleaux (20); 3) le support (16), qui est conçu pour porter le rouleau de film (17) peut être déplacé entre une position neutre qu'il prend pendant la formation de la balle cylindrique (15) et une position d'emballage des balles; 4) le dispositif supérieur de prise (18) peut être éloigné de la balle cylindrique (15), après sa formation, pour permettrre au support (16) de se mettre dans la position d'emballage des balles; 5) les rouleaux (20) du dispositif de prise inférieur (19) font tourner la balle cylindrique (15), après sa formation, autour de son axe longitudinal (21), tout en créant une rotation relative entre le rouleau de film (17) et la balle (15) autour d'un axe montant sensiblement perpendiculaire à l'axe longitudinal de la balle. Du film peut alors être prélevé sur le rouleau pour emballer la surface extérieure de la balle cylindrique.
