A method of placing thin-walled packages in a basket, box, or the like

The invention relates to a method for placing thin-walled packages 5 in a basket, box or the like, in which method the packages are arranged in predetermined groups and arranged in groups in baskets, boxes or the like reserved for the purpose.

Such packaging methods are now very well known in the food industry, for example. In these known methods, packages, for example milk cans, are lifted by gripping the brush portion of the cans. This limits the use of known methods and devices to packages with a brush or similar protrusion 15 on the top surface of the package. Thus, packages with a flat top surface, for example some packages of fresh juice, cannot be packaged at all by known methods, but must be packed by hand.

The object of the invention is to provide a method which can be used in connection with all known thin-walled, liquid-containing packages and which method is also advantageous and reliable in use.

The basic idea of the invention is that although the thin-walled package alone is relatively weak because the vertical, relatively long walls do not withstand high compression but indent, the group of several packages is surprisingly much stronger because the individual packages of the group form a kind of honeycomb structure, the packages support each other.

More specifically, the invention is characterized in that the packing group is fitted to the basket, box or the like by applying a simultaneous compressive force to the free vertical sides of the packing group, the packing group being held together by fitting

The invention has the advantage of its versatility, as the method can be used in connection with all known liquid-containing packages. In this case, packaging costs can be significantly reduced, as cumbersome and costly manual packaging is eliminated. It is also preferred that the same system can be used to handle different packages.

The invention will now be described in more detail by means of an exemplary embodiment described in the accompanying drawing, in which Figures 1 to 4 show the various steps of the method in principle.

In the figures, packages are denoted by reference numeral 1. The group formed by packages 1 is generally denoted by reference numeral 2. In principle, the pressing device 15 shown in principle is denoted by reference numeral 3. In addition, reference numeral 4 shows a basket, box or the like to which packages 1 are fitted. Fig. 2 also shows, by means of reference numeral 5, in principle a device by means of which a basket, a box or the like 4 can be moved. Figure 4 also shows a conveyor 6 by means of which the packaged packages 1 can be conveyed forward.

The method according to the invention works in the following way. The thin-walled packages 1, for example cans of milk or fresh juice, are transferred in the normal way to the line where they are grouped into equal groups. The size of the group can be, for example, 5x5 packages. This step is illustrated in Figure 1. This part of the method is a prior art technique that can be implemented in a number of different ways.

Figure 2, in turn, shows an essential feature of the method according to the invention. Em. the feature is that a simultaneous compressive force is applied to the free vertical sides of the group 2 formed by the packages 1. These forces are indicated in Fig. 2 by dashed lines P. 35. These forces P are used to hold the packing group together so that it can be fitted to a basket, box or the like 68576 4 without support on the lower surface of the packing group 2. The lower surface of the packing group 2 is thus completely free, so that the whole group seems to depend on the device 3 providing the pressing force P. The device 3 may, for example, comprise pressing plates 5 which can press all vertical sides simultaneously and which extend at least horizontally over the sides of the group 2. The group can also be supported from above as has been done in the example of the figure. What is essential, however, is that the method according to the invention does not grip the upper ends of the individual packages of the group 2, but the free vertical sides of the group, whereby the upper surfaces of the packages can be of any kind. Em. the mode of adhesion is made possible by the fact that the group 2 formed by the packages 1 withstands horizontal compression, even if the packages alone cannot withstand it. This is because the packages support each other sufficiently in the group, so that no harmful agglomeration can occur.

Fig. 2 further shows a preferred way in which the packing group 2 supported by the compressive forces P can be placed in a basket, box or the like 4. This can be done so that the group 2 is not moved but held in place by the compressive forces P and the base (not shown in the figures). ) on which the group 2 is initially removed, after which the basket, box or the like 4 is placed below the packing group 2 and lifted upwards so that the free bottom surface of the group 2 enters the basket, box or the like and rests on its bottom. The lifting is shown in Fig. 2 by the arrow N. When the bottom 30 of the packaging group 2 rests on the bottom of the basket, box or the like 4, the pressing is stopped, whereby the packages stand free. Next, the basket, box or the like 4 containing the packages 1 is moved downwards, for example to the conveyor 6. The lowering step is shown in Fig. 3 and the transport step in Fig. 4. In the example of the figures, the basket, box or the like 4 is lifted and lowered by the device 5 4 68576 through. This device is shown in Fig. 2 as a complete principle and the the device can, of course, be of any kind. The conveyor 6 shown in Fig. 4 is correspondingly shown in principle. The conveyor 6 can lead 5 to, for example, a warehouse or a loading place as required.

The above example is of course not intended to limit the invention, but the invention can, of course, be modified in many different ways within the scope of the claims. Thus, there can be any number of packages 1 in groups 2. The basket, box or the like 4 in which the packages 1 are contained (Fig. 3) also does not necessarily have to be lowered onto the conveyor 6, but other means, for example lateral or upward movement, are possible if it is considered appropriate for other reasons, etc.

Claims (3)

5,68576 A method for placing thin-walled packages (1) in a basket, box or the like (4), wherein the packages (1) are arranged in predetermined groups (2) and arranged in groups in purpose-built baskets, boxes or the like (4), characterized in that the package group (2) is fitted to a basket, box or the like (4) by applying a simultaneous compressive force (P) to the free vertical sides of the packing group 10, the packing group (2) being held together during fitting to the basket, box or the like (4) by the above pressing forces (P) without support on the lower surface of the packing group (2). Method according to claim 1, characterized in that the packing group (2) is fitted to a basket, box or the like (4) by supporting the packing group (2) in place by means of compressive forces (P), by placing the basket, box or the like (4) 2) below and by lifting the basket, box or the like (4) so that the free lower surface of the packing group (2) rests on the bottom of the basket, box or the like, whereby pressing is stopped and the basket, box or the like (4) containing the packages (1) are, moved away from the point where the above compression is performed. Method according to Claim 2, characterized in that the basket, box or the like (4), in which the packages (1) are contained, is moved downwards after the pressing has been completed.
