Definitions

  • the present invention relates to a procedure as defined in the preamble of claim 1 and an apparatus as defined in the preamble of claim 3 for wrapping a fresh-fodder bale in plastic.
  • a device for wrapping a round bale which is hitched to a baler and moves on its own wheels and which has picking devices for picking up bales from the ground, a wrapping table on which the bale is rotated, a wrapping arm provided with a plastic roll and a plastic holder and a plastic cutter.
  • the wrapping unit is hitched to the baler at a distance large enough to allow the wrapping arm to rotate without hitting the baler in any circumstances.
  • a bale gate at the rear of the baler is opened and the bale is dropped onto the ground, from where it is lifted by the picking devices of the wrap- ping unit onto the wrapping table.
  • the object of the present invention is to eliminate the drawbacks mentioned above and to achieve a procedure and an apparatus for wrapping bales in plastic that are reliable and easy to use.
  • the procedure of the invention is charac- terized by what is presented in the characterization part of claim 1.
  • the apparatus of the invention is characterized by the features presented in the characterization part of claim 3.
  • Other embodiments of the invention are characterized by what is presented in the other claims.
  • the solution of the invention has the advantage that the bale will catch no dirt from the ground, the fodder quality being thus improved.
  • Another advantage is that the bale can- not 'run away' even on sloping ground, because the bale is dropped from the baler directly onto the picking device of the wrapping unit.
  • the table can be properly tilted e.g. in a down-hill working situation to permit the bale to be properly moved onto the table, and, because of the guard, there is no fear of the bale falling down over the table.
  • a further advantage is that, at the end of the working period, the fodder material has been baled and the bales have been wrapped in plastic at the same time and gathered in the right locations. This is possible be ⁇ cause the wrapping time is shorter than the baling time, so when a new bale is still being formed, the wrapping of the previous bale will have been finished and there is still enough time left to move the wrapped-up bale to a desired location along the balirig route before the next bale is dropped onto the wrapping unit.
  • An additional advantage is that the bale is wrapped up immediately after baling, thus ensuring that the fodder will not suffer any detriment from the influence of air. This means improved fodder quality. Also, the bale cannot be soaked by rain between the baling and the wrapping.
  • Fig. 1 presents the baling and wrapping apparatus at the end of the baling phase in top view.
  • Fig. 2 presents the baling and wrapping apparatus during the wrapping phase in top view.
  • Fig. 3-6 present different stages of the wrapping process in side view.
  • the apparatus of the invention is described first to make it easier to understand the procedure.
  • the traction machine used is a tractor 1.
  • a baler 2 moving on wheels, which gathers the fodder mate ⁇ rial from the field and forms it into round bales 19 of a certain size, finally tying the bales.
  • a wrapping unit 3 moving on wheels, by means of which the round bale is wrapped in plastic imme ⁇ diately after the baling.
  • the basic part of the wrapping unit frame consists of a substantially horizontal drawbar 4, which is attached to the rear of the baler. Fixed at right angles to the rear end of the drawbar is a horizontal shaft with a rotatable wheel 22 at either end.
  • an overhead supporting arm 7 which rises upwards from the beam and is bent backwards in its upper portion.
  • the supporting arm carries a wrapping arm 8 rotatably mounted at its rear end.
  • the wrapping arm 8 is bent downwards essentially in the same shape with the over ⁇ head supporting arm, in a way that enables the wrapping arm to turn horizontally about its vertical joint without touch ⁇ ing the overhead supporting arm.
  • the wrapping arm is rotated by a hydraulic motor 18 mounted on the overhead supporting arm.
  • the power transmission is implemented e.g. by using a chain and sprockets.
  • the wrapping arm supports a roll of plastic placed in a vertical position at its lower end. The roll is revolved around the fodder bale 19 to be wrapped.
  • Each end of the shaft is provided with a lug for the wrap ⁇ ping table 10, placed close to the wheels 22.
  • the wrapping table is pivoted in the lugs by means of horizontal joints so that it can be tilted forwards and backwards to a suit- able position to allow a bale to be picked up or removed.
  • the tilting is implemented using hydraulic power means, one end of which is linked to the wrapping table and the other to the frame.
  • the wrapping table 10 is of rectangular form, consisting of two side beams and two end beams.
  • the table is linked to the shaft 20 by joints placed in the side beams.
  • the machine has two horizontal rotating rollers 17 linked to the side beams by bearings placed at the ends of the roll ⁇ ers, the rollers being mounted at right angles to the side beams.
  • the machine is provided with at least one belt 16 stretched around the rotating rollers so that when a fodder bale is on the belt, it will rotate along with the belt while at the same time the belt forms a concave pocket in which the fodder bale remains well in place during the wrapping operation.
  • the driving energy for the rotating rollers is obtained from a hydraulic motor mounted on the wrapping table.
  • the rear edge of the table is pro ⁇ vided with a guard 11 designed to prevent the bale from fal ⁇ ling off the table, mounted transversely to the direction of motion of the bale and attached to the table by its ends by means of turnable levers 12.
  • the levers 12 are turned by means of a hydraulic cylinder 13 linked at its first end to the wrapping table 10 and to the lever 12 at its other end.
  • the machine is provided with picking devices 5, mounted on each front corner of the wrapping table by means of a joint.
  • the position of the joint is so selected that, when the ta ⁇ ble 10 is inclined to its extreme position to pick up a bale, the joint is in an essentially vertical position, so that the picking device turning about the joint lies near the ground, rotating in an essentially horizontal plane, i.e. in practice parallel to the ground surface.
  • This ar ⁇ rangement allows bales of different diameters to be handled by the same apparatus.
  • the turning movement of the picking devices is produced by means of hydraulic power units 15, which are connected via joints to the picking devices 5 by one end and by the other end to lugs attached to the table 10.
  • the drawbar 4 has a telescoping structure, having inside it an extension bar 6 which forms an extension of the drawbar in the same direction with the latter and is attached to the rear of the baler.
  • the drawbar is moved in relation to the extension bar by means of a hydraulic cylinder 9 attached by one end to the frame of the wrapping unit and by the other end to the extension bar 6.
  • the wrap ⁇ ping unit is drawn close up to the rear of the baler just before the bale is dropped from the baler onto the wrapping unit to avoid dropping the bale to the ground.
  • the wrapping unit is pushed farther away from the baler by means of the hydraulic cylinder 9 and the wrapping process is started. Pushing the wrapping unit to a distance from the baler eliminates the risk of the wrapping arm hitting the rear of the baler e.g. when the working combination is turning.
  • the bale handling proc- ess is as follows: The operating cycle starts from the situation illustrated by Fig. 1. In this situation, the baler has nearly finished the baling process and the tying of the bale on the baler is beginning.
  • the solution of the invention uses logic control such that when the tying is started, the hydraulic cylinder 9 simultaneously begins to draw the wrapping unit 3 closer to the rear of the baler 2.
  • the wrapping arm 8 is in its standby position below the overhead supporting arm 7 and the picking devices 5 are also in a standby position with their free ends pointing towards the rear of the baler.
  • the operation of the guard 11 is so synchronised with that of the wrapping table and picking devices that when the table is tilted backwards beyond its horizontal position e.g.
  • the guard when working on a down ⁇ hill slope, the guard is in a vertical position, preventing the bale from falling down from the wrapping table. When the table returns to the horizontal position, the guard also moves down out of the way of the wrapping arm before wrap ⁇ ping is started.
  • the free end of the plastic wrapping 21 is held fast on the plastic cutter 14 while the other end is in the plastic roll placed at the lower end of the wrapping arm.
  • the wrapping ta ⁇ ble is tilted towards the baler, the picking devices forming a support for the bale falling down from the baler between the baler and the wrapping unit.
  • the bale gate 20 is opened, whereupon the bale is dropped onto the picking devices 5.
  • the bale is recognised by means of detectors and the wrapping table 10 is turned to its horizontal position as illustrated by Fig. 2, 4 and 5, the bale gate is closed and the wrapping table is drawn farther away from the rear of the baler by means of the hydraulic cylinder 9 and the picking devices 5 are turned in against the front edge of the wrapping table to keep them out of the way of the wrapping arm.
  • the combination is driven on and the baler starts forming a new bale from straw gathered from the field.
  • a detector detects the position and situation for the logic control and the wrapping phase is started by rotating the bale by means of the belts 16 and revolving the wrapping arm 8 around the bale, which is thus wrapped in plastic 21.
  • the rotation of the bale is slow during one revolution and is then accelerated slowly to avoid tearing the plastic during the initial jerk.
  • wrapping is continued through a number of revo ⁇ lutions set in the logic control and identified from the revolutions of the wrapping arm by means of a revolution counter.
  • the rotation of the bale is again slowed down during the last revolution to avoid stopping the rotation too abruptly and to allow the wrapping arm to be gently locked in its standby position.
  • the press arm of the plas ⁇ tic cutter 14 is lifted up according to the logic control and the wrapping arm is moved to its standby position in such a way that, during the last revolution, the plastic goes around the press arm of the plastic cutter.
  • the press arm is turned down again, crumpling the plastic in the di ⁇ rection of the plane of the plastic.
  • the arm compresses the plastic into a bunch against a press back stop and cuts the plastic so that the end of the plastic remains gripped be- tween the press back stop and the plastic roll on the wrap ⁇ ping arm as illustrated by Fig. 6, to be ready for the next bale.
  • the bale is free to be dropped down from the wrapping table.
  • the baling phase takes a longer time than the wrapping phase, so the baling process is continued and the newly wrapped bale is trans ⁇ ported on the wrapping unit to a suitable storage area.
  • the wrapping table is tilted backwards as shown in Fig. 6, the guard 11 is turned down to make way for the bale and the bale is dropped down off the wrapping table. After this, the wrapping table is turned back into its horizontal position and a new working cycle can begin.
  • the inven- tion is not restricted to the example described above, but that it may be varied within the scope of the following claims.
  • the ma ⁇ chine may have only one picking device, turnably mounted on one of the front corners of the wrapping table.
  • the picking device may also consist of a rectangular frame or plate placed at the middle of the table edge.
  • use of the wrapping unit is by no means limited to operation after a baler, but the same wrapping unit can also be used to pick up bales from the ground and by hitching it directly to a tractor or other hauling apparatus.
  • the logic control of the system of the invention is so implemented that the wrapping operation after baling and tying of the bale takes place completely automatically and the wrapping is performed by using commands entered into the logic control system and de ⁇ tectors mounted on the wrapping unit, without separate work contribution by the operator of the apparatus.
  • the operator can interrupt the operation of the automatic system and per- form the wrapping manually if required by the situation.
