Definitions

  • the channel is a horizontal channel open at the top, which carries near its front end a pair of horizontal bearing pins on which the flap is mounted.
  • the front end region of the channel is under a funnel, and the flap is approximately vertical, with its lower part closing the front end of the channel and with its upper part protruding into the funnel, so that the filling material falls into the channel , but cannot leave it at its front end.
  • the Spreading device has a nozzle through which air is introduced into a bag held in front of the channel in order to keep it open while the channel is being moved into it.
  • a piston-cylinder arrangement is assigned to the channel for its horizontally reciprocating movements. By means of a further piston-cylinder arrangement, a piston-like slide can be moved back and forth in the channel in order to push the filling material out of the channel to the front when it is immersed in the bag.
  • This known device is suitable for bulk goods of only moderate bulk, such as carrots.
  • the known device is in any case not suitable if the cross section of the channel and thus also the bag to be filled is not significantly larger than the largest root ball cross section of shrub plants. If the shrub plants were packed in appropriately large bags, their root balls would be insufficiently protected against drying out.
  • a device for packaging shrub plants which has a bed for placing shrub plants below a hopper for feeding shrub plants and a pair of mold jaws between which the shrub plant is compressible in such a way that it can subsequently be pressed together of a slide can be pushed transversely to the direction of movement of the two mold jaws through a mouthpiece into a container which has previously been pushed onto the mouthpiece. Only a few, particularly robust plant species can withstand the force effects associated with these processes undamaged.
  • devices which serve to fill plastic film bags with bulk material, for example potatoes.
  • protruding edge regions of bags which are formed by a film web and are not yet separated from one another are drawn in the longitudinal direction of the film web over a spreading body in such a way that the bag edge regions which extend in the longitudinal direction of the film web and are not connected to one another are spread apart and as long as possible be kept separate until a desired amount of filling material has been introduced into the container.
  • These known devices are not very suitable for contents which are bulky and tend to get caught on the bag.
  • the invention is therefore based on the object of designing a device for filling bags in such a way that it is also suitable for packaging recalcitrant shrub plants with bales.
  • the invention is preferably further developed in that a channel open at the top opens into the conveyor trough in its open position, into which the shrub plants fall at intervals from one another from a conveyor. This results in a pre-orientation of each shrub plant in the conveyor trough, which is then only responsible for aligning the shrub plant exactly in the longitudinal direction of the dip tube.
  • a plunger for inserting the shrub plants into the bag can be moved back and forth in the dip tube, as in the channel of the device known from US Pat. No. 4203269. If the dip tube is arranged sufficiently steep, in particular vertically, the contents will generally tend to slip through the dip tube into the bag; with the stamp described you get yourself at especially bulky shrub plants the certainty that the bottom of the bag is reached by the plant bale in any case.
  • a holding device is arranged on the other side of the expansion tube for holding the filled bag when the immersion tube is withdrawn. In this way it can be prevented with certainty that the immersion tube takes a particularly bulky shrub plant with it when it is withdrawn.
  • the system shown is used to place balled shrub plants 10 in a bag 12 made of shrinkable film and to close the bag in the area between plant shoots and root balls by locally shrinking.
  • the bags 12 are, still interrelated, formed in a tubular film web, which is conveyed upright in a vertical longitudinal plane through the system and is slit open at the top.
  • the individual bags 12 are delimited by vertical weld seams 14 which end below the upper bag edge regions 16 which are separated from one another by the slitting.
  • Each bag 12 has a viewing surface 18 facing the viewer of FIG. 2, onto which an adhesive label 20 is to be glued.
  • a binding label 22 is also to be added to each bag 12, which can be attached to the plant 10 when it is removed from the bag 12 at the planting location.
  • Each binding label 22 has an eyelet 24 in which a binding wire 26 is fastened.
  • the adhesive label 20 should be glued over the binding wire 26 and, for the sake of safety, also over the area of the eyelet 24.
  • shrinking the bag 12 should eventually form a neck 28; below and also above the neck 28, the bag 12 should not be affected by the shrinkage or only relatively little.
  • the system shown has an elongated machine frame 30, at the beginning of which, in FIGS. 1 and 2 on the right, a vertical decoiler 32 for the film web is mounted, in which the bags 12 are formed.
  • the film web runs gradually over a tensioning roller 34 and over deflection rollers 36 and along a vertical support surface 38 to a vertical expansion tube 40, which in plan view according to FIG. 1 has the shape of a ship's hull pointed at both ends.
  • the spreader tube 40 engages between the upper bag edge regions 16 projecting beyond the weld seams 14 and spreads them apart after each conveying step of the film web above a bag 12 to such an extent that the relevant bag 12 opens for receiving a balled plant 10.
  • a take-up reel 44 Arranged above the rear end of the machine frame 30, which is on the left in FIGS. 1 and 2, is a take-up reel 44 for winding up the upper bag edge regions 16 torn off from the bags 12.
  • a common motor 46 is provided for rotating the take-up reel 44.
  • an adhesive label dispenser 48 and, above it, a binding label dispenser 50 are arranged.
  • the adhesive label dispenser 48 as such is of a known type and is therefore not shown in detail.
  • the binding label dispenser 50 has six label containers 52, each of which is attached to the end of an arm 56 which projects radially from a vertical shaft 54.
  • a longitudinal conveyor 86 for example in the form of a conveyor belt, is provided to bring the plants 10, which are to be put into a bag 12 each, which rises like a ramp to a transversely lying, open channel 88 and on which the plants 10 fall one after the other at intervals leaves.
  • a plant 10 can be displaced radially in the direction of the vertical axis B of a dip tube 92, for example by a slide 90 that can be moved pneumatically back and forth.
  • the dip tube 92 is arranged coaxially with the expansion tube 40 and can be moved up and down by a drive 94, for example a pneumatic piston-cylinder unit, between a take-over position in which the dip tube 92 only protrudes into the expansion tube 40 from above and a lower end position, in which extends the immersion tube far into the bag 12 held open by the expansion tube 40, if necessary almost to the bottom thereof.
  • a drive 94 for example a pneumatic piston-cylinder unit
  • the immersion tube 92 has a semi-tubular section 96, to which a likewise semi-tubular delivery channel 98 is assigned.
  • This conveyor trough 98 is connected at its lower edge to the dip tube 92 by a joint 100 with a horizontal pivot axis C.
  • the conveyor trough 98 opens diagonally into the dip tube 98 so that it can take over a plant 10 from the transverse channel 88.
  • the conveyor trough 98 is guided in such a way that it supplements the semi-tubular section 96 to a completely closed pipe section when the immersion pipe 92 is lowered. As a result, the plant 10 is forced to participate in the downward movement of the dip tube 92 and can only slide downward in it.
  • the downward slide of the plant 10 within the dip tube 92 is promoted by inertial forces when the downward movement of the dip tube is stopped more or less abruptly. This may be sufficient to cause the plant 10 to slide downward in the dip tube 92 until the root ball settles on the bottom of the bag 12 into which the dip tube is immersed.
  • a plunger-like stamp 102 is assigned to the dip tube 92, which normally assumes a rest position in the upper end region of the semi-tubular section 96 or even above it.
  • the plunger 102 is connected to a piston-cylinder unit 104, which moves it downwards during or immediately after the lowering of the dip tube 92, so that the plunger 102 will certainly push the plant 10 down until its root ball is on the bottom of the bag 12.
  • a holding device 106 is arranged below the expansion tube 40, the function of which is to hold the bag 12 and the plant 10 introduced into it, preferably at their root ball, while the dip tube 92 is again moved upwards into its take-over position.
  • the holding device 106 has a pair of jaws 108 which, for example, can be moved pneumatically towards and away from one another.
  • the entire film strip on which the bags are formed is moved one step further.
  • the bag which has just been filled comes into the area of action of a front nozzle 110 of each of the two nozzle groups 42, so that hot air escaping from them begins to cause the neck 28 to shrink.
  • said bag 12 is exactly between two pairs of middle nozzles 112; the hot air flowing out of them continues the shrinkage at the neck 28.
  • the right edge region of the neck 28 in FIGS. 1 and 2 is located between rear nozzles 114 of the two nozzle groups 42, so that the shrinkage concentrated on the neck 28 is completed.
  • the two nozzle groups 42 are supplied with hot air by a blower 116 each time a bag 12 has reached its area of influence. Careful thermal insulation of the nozzle groups 42 prevents excessive cooling in the intervals at which the fans 116 are stopped.
  • the bag edge regions 16 are torn off the correspondingly perforated or otherwise prepared film web and wound up by the take-up reel 44. Simultaneously or immediately thereafter, the filled bags, which have been shrunk at their neck 28, are separated from one another by means of a separating device 118 and conveyed further by a longitudinal conveyor 120 and finally by a cross conveyor 122.
