Abstract
The invention relates to a compression plate, which ensures a tight wrapping of continuous film on at least one compressible object during a packaging process. Prior to closing the continuous foil wrapped around the compressible object, the compression plate compresses the compressible object unevenly so as to ensure a desired shape of the packed compressible object after closing the continuous foil.
Description
- The invention relates to a compression plate, which ensures a tight wrapping of one or more compressible objects.
- In the industry of insulation materials it is of outmost importance that the cubic content of the packets of insulation material is reduced to a minimum, enabling transportation of an increased number of packets per volume. Further, in order to simplify both the transportation of insulation material and to enhance the operability of the packages of insulation material on site, it is desired to bundle multiple packages of insulation material.
- In general, compressible objects such as insulation materials are only compressible in one direction. Compression in any other direction than this will damage the properties of the insulation material. This unidirectional compression characteristic results in a number of problems described in the following.
- Horizontal compression could also be performed. Here e.g. three packages of pre-compressed objects are led horizontally into a vertically oriented foil and are horizontally over-compressed. At this point three surfaces (top, bottom and one end) are covered in foil, the last and fourth surface is not yet covered. In order to maintain that over-compression before the foil is closed, spears are directed at the back of the last of the three packages—just in front of the fourth surface. The foil is hereafter closed and the spears withdrawn. Consequently, some of the potential energy of the over-compressed objects is released, whereby the objects expand and the foil is tightened. The over-compression causing the expansion of the objects is, however, undesired, as this can potentially destroy intended function of the objects. In the case of insulation material this could then lead to a reduction of the insulation properties. A solution to this could be to reduce the over-compression to a minimum. However, in the present example of three compressible objects that are bundled and packed in one, there is a risk that the centre object will fall out of the package. This is because most of the potential energy of the compressed objects will be released during expansion. The remaining potential energy is not sufficiently high to keep the centre object in place, which then risk falling out of the final package.
- In the case of vertical compression, e.g. three packages—comprising a plurality of stacked objects—are led horizontally into a vertically oriented foil. Due to the unidirectional compressibility of the objects, they are only led into the foil without any horizontal compression. When three sides of the three packages have been covered in foil, spears are directed in front of the fourth side. Hereafter the objects are compressed, the foil is closed at the fourth side, and the spears are closed. Since the objects are directed into the foil in an uncompressed state, the length of the foil will be larger than the circumference of the compressed objects. Withdrawing the spears and removing the compression will therefore release the potential energy of the objects, which will expand. However, as there is more space left in the end of the package because of the withdrawn spears (fourth side), this expansion will be uneven. Hence, the final package that was to be rectangular will instead have an irregular shape, by e.g. having a larger height in one end, compared to the other.
- The present invention relates to a packaging machine for packaging at least one compressible object into foil comprising at least one compression plate, where the at least one compression plate comprises at least two segments which can be sloped individually, whereby it is obtained that the at least one compressible object can be unevenly compressed by the compression plate during the packaging process of the at least one compressible object. This is advantageous as the uneven compression of the compressible objects enables a desired uneven expansion of the compressible objects, when the compression plate no longer exerts its compression. Hereby an even final package is obtained. If the packaging machine employs spears as described above, the compression plate can advantageously compress the compressible objects more in the end of the spears. This because the foil wrapped along and around this end of the compressible objects and the spears lengthwise will correspond to the foil wrapped around the objects in the opposite and less compressed end. A further advantage is that the compression plate only compresses the compressible objects in the direction where the compressible objects are compressible. Damage to the properties of the compressible objects is thereby avoided.
- In another embodiment of the packaging machine the at least two plate segments are interconnected by at least one hinge. In a further embodiment the compression plate further comprises at least one hinge connected to one of the at least two plate segments. Apart from the advantages already mentioned, this embodiment is advantageous as e.g. the number, form and size of the plate segment and hinges can be varied for example to accommodate a desired product type or product range.
- In yet another embodiment of the packaging machine the compression plate comprises a flexible plate and at least one eyelet mounted on the flexible plate for separating at least two segments of said flexible plate. This embodiment is advantageous as the bending of the flexible plate can constitute a more coherent surface.
- In other embodiments of the packaging machine, the compression plate compresses the at least one compressible object by pneumatic means or hydraulic means. In a further embodiment of the packaging machine the compression is employed by means of linear actuators. These different means are advantageous as they can be used to serve different purposes depending on e.g. the properties of the compressible objects and/or existing manufacturing equipment.
- The present invention further relates to a method for wrapping a foil onto at least one compressible object, comprising the steps of wrapping at least one side of the at least one compressible object whereby the foil covers the at least one side and compressing the at least one compressible object unevenly. In a further embodiment the method comprises the step of closing the foil after the at least one compressible object has been unevenly compressed. Here the advantages are as described above.

At this point of time in the process, thesecond segment 123 of thecompression plate 119 is oriented horizontally and thefirst segment 121 is sloping downwards relative to the conveying direction. That is the end of thefirst segment 121 facing thesecond foil 113 is positioned higher relative to the end of thefirst segment 121 facing thesecond segment 123.
