Definitions

  • the invention relates to a device for packaging objects according to the preamble part of Claim 1.
  • a device of this kind for packaging objects such as rectangular containers made of laminated paper, metal and/or plastic sheets and containing a liquid such as milk, juice etc. is known from the WO-A-79/00 102.
  • packaging units are produced, in which the objects are arranged in two subgroups in rectangular arrays on a tray folded from corrugated board.
  • Each tray has a double layered partition wall which is folded upwardly and extending across said tray dividing it into compartment, each compartment containing a subgroup of ubjects.
  • the partition wall is provided with a perforated line, whereby the compartments are separable from each other to form separated box shaped trays each containing a group of objects.
  • This packaging unit has the advantage that the packaging machine may be used with its full capacity by forming packaging units comprising a rather large array of objects.
  • the large units can be separated into smaller sub-units at any desired time and location, either at the packaging side itself or by the transporter, the distributor or the user.
  • the objects are collected separately to form the subgroups which are then separately transferred to a precut sheet of corrugated board. After the transfer the subgroups are moved with respect to each other whereby the part of the sheet which is between the subgroups is folded upwardly to form the partition wall. As the subgroups are arranged and transferred separately and as they have to be moved with respect to each other the speed of the packaging process is rather limited.
  • the objects are collected together on a single collecting surface and the subgroups of objects are transferred at the same time by a single transfer pusher to the prefolded sheets. So the partition wall can be formed at an earlier stage of the process and no movement of the subgroups with respect to each other is required.
  • Figure 10 illustrates an arrangement where the same number of objects A are packaged according to the present invention, using a pre-cut sheet b 2 as shown in Figure 11.
  • the two halves b', b' are located at either side of a perforated line c, and the sheet b 2 is folded into the form b' 2 shown in Figure 12, with the flaps f located at either side of the perforated line c folded upwardly to form a double-layered partition wall, which together with the upwardly folded end walls e confines two compartments d.
  • Figure 15 illustrates an arrangement in which the same number of objects A are packaged according to the invention using a pre-cut sheet b 4 as shown in Figure 16.
  • the sheet b 4 is pre-folded to the shape shown in Figure 17 for receiving the objects which are pushed into the three compartments d in a direction parallel to the perforated lines c, whereafter the side wall flaps g and the securing flaps h are folded and secured.
  • a pair of left and right vertical belts 2 and 2 are provided on the front end part of a continuously driven conveyor 1 for conveying the objects.
  • These vertical belts 2 and 2 which are intermittently driven, feed forward the commodities or objects A conveyed on the conveyor 1 such that they are assembled into groups of, for example, three articles each.
  • a collecting pusher 3 which is provided in front of the vertical belts 2 and 2, is actuated in a direction perpendicu tar-to the travelling direction of the conveyor 1, thereby pushing forward (toward the right side of Figure 1) the objects A three pieces by three pieces.
  • This position p to which the objects A are fed is the collecting section, which, as shown in Figures 2 and 3, is equipped with a partition plate 4 provided perpendicularly to the actuation direction (longitudinal direction of Figure 1) of the above-mentioned pusher 3, a receiving plate 7 which is arranged on the right side of and parallel to said partition plate 4 and a transfer pusher 8 which pushes the array of collected objects to the side (to the lower part of Figure 1).
  • said partition plate 4 is connected with two cylinders 5 and 6 so that the actuation of cylinder 5 causes said partition plate 4 to make an advance toward the pusher 3, while exhausting .
  • the pressure from the cylinder 5 causes the same to make a gradual retreat.
  • the actuation of the cylinder 6 causes the partition plate 4 to be pivoted up sideways as shown by two-dot chain line 4' of Figure 3.
  • the receiving plate 7 is caused to make an advance toward the pusher 3 by the actuation of the cylinder 7a, whereas it is caused to make a gradual retreat by exhausting the pressure from the cylinder 7a.
  • the cylinder 6 is actuated to extend its piston rod whereby the partition plate 4 is lowered as shown in the dot line of Figure 7-(c), so as to lie against the rear end face of the 12 collected objects.
  • the pusher 3 is actuated again so that the next group of three objects are pushed out forward and since the partition plate 4 is inserted between the group of 12 objects previously collected and the objects presently being collected as shown in Figure 7-(d), these two groups are separated from each other and, as shown in Figure 7-(e), the reciprocating motion of the pusher 3 provides another group of 12 objects to be collected on the left side of the partition plate 4.
  • the pusher 8 is actuated and pushes out the two groups of collected objects. As shown in Figure 3, there is a sufficient clearance between the lower edge of the partition plate 4 and the collecting surface to allow the transfer pusher 8 to pass through without being impeded by the partition plate 4.
  • the cylinders 5, 6, and 7a are actuated so that the partition plate 4 and the receiving plate 7 correspondingly return to the positions shown in Figure 7-(a), standing ready for the next collecting cycle.
  • a tray sheet folding device as shown in Figures 4 to 6.
  • This sheet folding device comprises a sheet dropping device 10 provided above a feeder 9 for transferring the tray sheet as well as a flap folding device 11.
  • Said sheet dropping device 10 comprises, for example, a pair of left and right suction heads actuated by a cylinder 10a to pull down individually the tray sheets b 2 which are accumulated above the feeder 9, starting from the bottom sheet to the next one.
  • the flap folding device 11 has upstanding left and right folding plates 11a and 11a and a folding blade-llb interposed between those plates as shown in Figure 6, and is capable of vertically moving by means of a cylinder 11c; when said flap folding device 11 makes an ascent, the two left and right folding plates 11 a and 11 a fold the external left and right flaps e and e of the tray sheet which is pulled down by the tray sheet dropping device 10 and the intermediate folding blade folds the flaps f and f connected by the perforated line c as shown in Figure 4, thereby forming the sheet into a shape having left and right compartments d as shown in Figure 12.
  • an adhesive applicator 12 applies adhesive 13 to four external flaps g which are not yet folded and the tray sheet is then pushed out on a discharging feeder 14 advancing (in the direction indicated by the arrow in Figure 1) and passing by a flap folding device (not shown) which folds the internal flaps h and the external flaps g, thereby forming such a finished tray B 2 as shown in Figure 10, which is discharged.
  • the tray sheet dropping device 10 is located within the frame of the flap folding device 11 and does not impede the vertical motion of the latter device.
  • the folding tool or tools may be changed according to the shape and size ofthetraysheets.
  • a conventional tray sheet b as shown in Figure 9 and or a tray sheet b 3 as shown in Figure 14
  • only the two folding plates 11 a are employed in the flap folding device 11 or, alternatively, when performing the packaging with a tray sheet b 4 as shown in Figure 16, a flap folding device 11 having two left and right folding plates 11 a and two folding blades 11 b, is employed.
  • the packaging device of the present invention by performing at least one partition wall in the tray sheet at least two compartments are formed for receiving groups of objects which have previously been collected in the predetermined number. This enables efficient packaging of the objects on fold-box type trays without reducing the capacity of the packaging machine. Furthermore, by using different shapes of tray sheets it is possible to perform the packaging into smaller collecting patterns whilst of keeping the total number of objects to be packaged the same.
  • packaging units as shown in Figures 8,10,13 and 15 may be delivered without being further treated, it is possible to apply shrinking film packaging by surrounding the peripheries of the packaging units polyethylene film. In that case, it is recommendable to provide the film in advance with a perforation running along the perforated line c of the tray sheet in order not to impede the separation of the packaging unit into two or more parts.
