Definitions

  • the invention relates to an apparatus for transferring bottles provided with an extending collar at their neck, such as PET-bottles or alike, from a crate having a partially open bottom towards a conveyor engaging the neck of each bottle.
  • a conveyor may be of the type described in Dutch patent application 90.01589 of applicant, in which two distanced endless driven conveying elements, for example belts, receive between them the neck of each bottle.
  • an apparatus for transferring bottles provided with an extending collar at their neck, such as PET-bottles or alike, from a crate having a partially open bottom towards a conveyor engaging the neck of each bottle, the apparatus comprising a conveying device for horizontally moving the crate and lifting means which at least temporarily move onwards synchronously with the crate, said lifting means being movable upward and downward relative to the crate for engaging the lower side of the bottles and thus lifting these in such a way that their neck may be gripped by the conveyor.
  • a supplied crate filled with bottles is positioned on the conveying device which horizontally propels the crate. During, or previously to, this propulsion of the crates the lifting means lift the bottles such that the neck thereof projects beyond the upper edge of the crate. In this position the necks may be engaged by the conveyor positioned above the conveying device for further removing the bottles.
  • the apparatus according to the invention has fulfilled its function when the bottles are lifted relative to the crate in such a way that their necks may be engaged by the conveyor. Entirely removing the bottles from the crate thereafter is carried out by the conveyor. In this respect it is essential that the distance between the conveyor and the crate increases in the propulsion direction of the crates.
  • the crates, after engagement of the bottles by the conveyor keep on moving horizontally whereas the conveyor follows an upwardly inclined track, such that the bottles are lifted out of the crate.
  • the conveyor follows a horizontal track whereas the crates, after engagement of the bottles by the conveyor, follow an downwardly inclined track. Now also the bottles are lifted out of the crate.
  • a combination of both previously mentioned possibilities also leads to a good result.
  • the conveyor engaging the neck of the bottles also could comprise a stationary guiding.
  • the increasing distance between the conveyor and the crate will be realized by moving the crates inclined downwardly.
  • the conveying device comprises at least one slide for housing at least one crate, in which slide the lifting means are mounted movably upward and downward.
  • the supply of the crates to the slides occurs in a way not described further, for an expert however easy to realize, such that each slide houses at least one crate.
  • the lifting means, which are part of the slides, thus are automatically positioned correctly relative to the bottles present in the crate, such that the lifting means function in a reliable way.
  • the conveying device comprises an endless belt carrying the slides.
  • the apparatus may operate continuously.
  • the supplied crates are positioned at one side of the conveying device and are removed at the other side. In the intermediate section the removal of the bottles from the crates occurs.
  • each lifting means is provided with follower rolls cooperating with a stationary curved track. It is possible, for example, that each lifting means has its own follower roll, so that through an appropriate choice of the shape of the curved track care can be taken that each bottle is presented correctly to the neck engaging conveyor. Lifting a bottle then occurs always at the same position of the conveying device.
  • an embodiment of the apparatus may be realized, in which the lifting means are provided with such a drive mechanism, that they carry out at least a vertical motion for lifting the bottles and successively a horizontal motion for propelling the crates. So the lifting means now constitute the conveying device for the crate too.
  • the drive mechanism comprises two similar endless chains or alike, which, positioned above each other, each occupy a vertical plane and describe a mainly rectangular track, wherein the corresponding sections of the chains are connected by a connection member carrying the lifting means.
  • the lifting means of a crate are interconnected and are movable upward and downward together.
  • all bottles are commonly moved upward and downward.
  • the lifting means of one single crate are now operated by one single follower roll, such that the motion of the lifting means occurs simultaneously.
  • lifting means which comprise pins movable upward and downward through the bottom of the crate.
  • the pins are provided in a pattern which corresponds with the pattern of the bottles in the crate, so that always one single pin engages a single bottle.
  • the lifting means comprise radial projections of a vertical wheel positioned below the conveying device, wherein a part of the circumference of the wheel is substantially tangent with the track of the crates propelled by the conveying device and of which wheel the circumferential velocity substantially corresponds with the propulsion velocity of the conveying device. Because the radial projections of the vertical wheel follow a circular track they move upward and downward relative to the crate. So these radial projections may function as lifting means and may lift the bottles relative to the crate.
  • the apparatus comprises in the shown embodiment a conveying device 1 comprising slides 3 which are interconnected by an endless chain 2 or alike and which are supported by a guiding 4.
  • the chain 2 is driven in such a way that the slides 3 follow an endless track in the direction indicated with arrows.
  • the slides 3 are provided with a recess 5 for housing a crate 6 in which the bottles 7 are positioned.
  • recess 5 it is also possible that the slides 3 comprise at the upper side carriers for in a controlled way receiving a crate 6.
  • the crates 6 filled with bottles 7 are supplied to the apparatus through a supply device 8 only indicated schematically.
  • a supply device several devices known per se may be used, such as a chute or a conveying belt. Appropriate means may be provided then for at the correct moment supplying a crate 6 to a passing slide 3.
  • the bottles 7 present in the crates 6 are provided with an extending collar 9 at their neck (see Fig. 2) onto which a conveyor 10 positioned above the apparatus should engage.
  • bottles may comprise the so-called PET-bottles.
  • the conveyor 10 positioned above the apparatus preferably comprises a conveyor of the type as described in Dutch patent application 90.01589, of which the conveying elements comprise belts or alike engaging the neck of the bottles to be conveyed.
  • Each slide 3 comprises a lifting device 11 to be elucidated further referring to Fig. 2, which in co-operation with a stationary curved track 12 realizes the partially lifting of the bottles 7 out of the crate 6.
  • the bottles 7 lifted thus are presented to the conveyor 10 that then entirely removes the bottles from the crates 6 and discharges them.
  • the empty crates 6 are, in a way not shown further, presented to a discharge device 13 indicated only schematically that may mainly correspond with the supply device 8.
  • the lifting device 11 of the slides 3 comprises a number of interconnected pins 14 which are housed movable upward and downward in recesses 15 shaped in the slides 3.
  • the pins 14 carry a follower roll 16 following the curved track 12.
  • the pins 14 of the right-hand slide 3 in Fig. 2 are in their lowermost position as a result of the co-operation between the follower roll 16 and the curved track 12. In this position the uppermost ends of the pins 14 do not engage the bottles 7 present in the crate 6.
  • the follower roll 16 has been moved upward by the curved track 12 such that the pins 14 have reached their uppermost position. In this position they engage the bottom of the bottles 7 and have lifted these bottles 7 relative to the crate 6. The distance over which the bottles 7 are lifted is such that a neck provided with a collar 9 extends beyond the upper edge of the crate 6. So the conveyor 10 may engage this collar 9.
  • the crate While lifting the bottles 7 relative to the crate 6 the crate functions as a guiding for the bottles 7 prohibiting the bottles from tumbling down.
  • the slide 3 with crate 6 reaches the position according to the left-handed slide 3 in Fig. 2.
  • the follower roll 16 has left the curved track 12 and the pins 14 have reached their lowermost position again.
  • the bottles 7 have been removed almost entirely from the crate 6 as a result of an upwardly inclined direction of the conveyor 10. It is noted that generally the propulsion velocity of the conveyor 10 equals the propulsion velocity of the conveying device 1, so that no relative velocity occurs between the bottles 7 conveyed by the conveyor 10 and the crates 6 which could result in jamming.
  • the lifting device for lifting the bottles 7 is not movable upward and downward through a curved track 12 but through separately activatable drive means, such as cylinder-piston assemblies.
  • the shape of the curved track 12 may be varied widely too.
  • the curved track extends in Fig. 1 and Fig. 2 only over a small part of the entire apparatus it is possible too that the curved track extends all the way around, such that the follower rolls 16 are always received in this curved track.
  • the bottles are positioned in a special pattern beside and behind each other.
  • the pins 14 of the lifting device 11 may be provided in correspondence with this pattern.
  • the basic principle of the apparatus according to the invention does not change however.
  • FIG. 3 An alternative embodiment of the apparatus according to the invention is shown in Fig. 3.
  • a vertical wheel 18 is positioned below the conveyor 16 having radial projections 19.
  • Part of the circumference of the wheel 18 is substantially tangent to the track of the crates 6 propelled by the conveyor 16.
  • the circumferential velocity of the wheel 18 substantially corresponds with the propulsion velocity of the conveyor 16.
  • the shape of the crates 6, in which the bottles 7 are present should enable the movement therein of the radial projections 19.
  • Fig. 4 a different alternative embodiment of the apparatus according to the invention is illustrated.
  • two endless chains 20 and 21 are provided which are each positioned in a vertical plane and follow a substantially rectangular track and which extend around guiding rolls 22.
  • Corresponding sections of the chains 20 and 21 are interconnected by a connection member 24 carrying the lifting means 23. If now the chains 20 and 21 are driven synchronously the connection member 24 will follow a nearly rectangular track, while maintaining its illustrated upright position. In the position illustrated in full lines the connection member 24 is in a track section where it moves vertically upwards (as a result of the direction of movement of the chains 20 and 21 indicated by arrows). Now with the lifting means 23 it may engage the bottles 7 in a crate 6 which is present on an appropriate support 25. So the bottles 7 are lifted. Next the connection member 24 will follow the horizontal track sections of the chains 20 and 21, as indicated in the uppermost dotted position of the connection member 24. Now the lifting 23 have not only lifted the bottles 7, but also propel the crate 6 along the support 25.
  • connection member 24 is moved downwardly vertically and will be moved back through the lowermost horizontal track sections (as indicated by the dotted represented position). Now the crate is freed.
  • bottles can be removed from crates 6 and can be supplied to a conveyor 10.
  • the apparatus according to the invention is used for transferring bottles 7 from a conveyor 10 into the crates 6.
  • a reversal of the direction of motion of the several parts of the apparatus would be sufficient.
  • the required devices belong to the domain of control engineering and do not fall within the scope of the invention.
