DEVICE FOR ADJUSTING HEIGHT OF A PACKAGE BOX AND FOR CLOSING THE BOX
A device for adjusting height of a prefabricated package box (1) and for closing the box, wherein the box (1) comprises a forehand made ware filling (4) to a certain height (L) and the box (1) comprises a wall, the thickness of which is not less than 2 mm, wherein the device comprises. The device comprises a measuring device (2) for detecting the filling height (L) in the box (1), a supporting means (5),(6),(7) placeable inside the box (1) and mounted against the box (1) wall and being adjustable of its height position, a work piece (8) mounted outside the box (1) said work piece being arranged to make horizontally directed folding tracks in the outer surface of the box (1), cutting means (10) for cutting open the corners of the box (1), and devices for turning the flaps (13, 14) formed in the upper edge of the box (1) and for mounting a cover onto the box (1),
The invention relates to a device for adjusting height of a prefabricated package box and for closing the box, wherein the box comprises a forehand made goods filling to a certain height and the box comprises a wall, the thickness of which is not less than 2 mm, wherein the device comprises:
-
- a measuring device for detecting the filling height in the box,
- a supporting means placeable inside the box and mounted against the box wall and being adjustable of its height position,
- a work piece mounted outside the box said work piece being arranged to make horizontally directed folding tracks in the outer surface of the box,
- cutting means for cutting open the horns of the box, and
- devices for turning the flaps formed in the upper edge of the box and for mounting a cover onto the box.
Earlier is known a device according to the preamble above from publication EP 1832413 where the adjustment of the box height is presented according to the height of the goods filling. For adjusting the box height fold line markings, like pressings or scorings round the box are made on the box walls on their both sides at the height defined by the ware filling, after which in the next station the box wall portions of each sides of the box above these height lines are folded as flaps closing the box. The pressing lines are steering the foldings in desired points and are also facilitating the folding.
The disadvantage for this known solution is that after their foldings the flaps are trying to return back up, and therefore the flaps are needed to keep folded until a cover can be mounted onto the box. In the known solutions the flaps are glued together for securing that they keep folded. If the box wall is made of normal box cardboard, like corrugated board thickness 3-4 mm, may the foldings break uncontrolled the folding lines. Also one can meet difficulties when mounting cover, when in the folding line level the folding line of the flap can locate either on the inner or outer surface of the box.
For eliminating these disadvantages a new device has been developed for adjusting the box height according to the filling volume and a device for closing the box using flaps and cover. Characteristics for the device according to the invention is that the work piece for making folding tracks in the outer surface of the box is cutting work piece, which cuts from the outer surface of the box to an adjusted deep extended cutting lines.
Advantageous for the invention is that the inner surface of the box stays unbroken. The film of the inner surface in the box functions as a hinge for the folded flaps, the folding does not comprise any binding which would turn the flaps back up. The folding lines of the flaps become accuracy i.e. the flaps will fold according straight lines and locating on correct levels. It is very easy to make outside the box cuttings on adjusted level so, that the inner surface of the wall stays uncut. The filling height of the boxes transported to the device can be automatically detected by means of a scanner device or by means of a mechanical inside the box lowered measuring device, which measures the highest location of the filling in the box and all in this way of their fillings measured boxes can be manufactured so that their heights are minimized for saving space.

Claims
1. A device for adjusting height of a prefabricated package box (1) and for closing the box, wherein the box (1) comprises a forehand made ware filling (4) to a certain height (L) and the box (1) comprises a wall, the thickness of which is not less than 2 mm, wherein the device comprises:
- a measuring device (2) for detecting the filling height (L) in the box (1),
- a supporting means (5),(6),(7) placeable inside the box (1) and mounted against the box (1) wall and being adjustable of its height position,
- a work piece (8) mounted outside the box (1) said work piece being arranged to make horizontally directed folding tracks in the outer surface of the box (1),
- cutting means (10) for cutting open the corners of the box (1), and
- devices for turning the flaps (13, 14) formed in the upper edge of the box (1) and for mounting a cover onto the box (1),
- characterized in that the work piece (8) for making folding tracks in the outer surface of the box (1) is cutting work piece (8), which cuts from the outer surface of the box (1) to an adjusted deep extended cutting lines.
2. A device according to claim 1 characterized in that said device comprises a control unit for adjusting the height level of the horizontally in adjusted deep cutting work piece (8) to be essentially at least the filling height level (L).
3. A device according to claim 1 characterized in that the support device (5, 6, 7) is placed inside the box (1) and adjusted to support the wall of the box (1) on the level of the filling height (L) or close above it.
4. A device according to claim 1 characterized in that there are cutting work pieces (8) one piece per each side of the box (1).
5. A device according to claim 1 characterized in that the cutting work pieces (8) are connected to carry out the cutting motion together by means of the same driving means, like a pulling means which is led via the work pieces (8).
6. A device according to claim 1 characterized in that the cutting work pieces (8) are adjusted to leave the inner surface of the box (1) uncut.
