Description:
A PACKAGE FORMING DEVICE AND THE WAY OF FORMING PACKAGES

The subject of invention is a device to form packages and the way of forming packages which allows to make packages, especially cardboard ones, of different sizes matching a consignment's variable volumes.

A system of assorting package sizes described in patent EP 2858909 being used by Boxsizer Ltd. is already known. After goods are packed into an open carton box a machine cuts vertically on edges and makes horizontal engravings matching the height of the box with its contents. The box is later automatically locked and sealed.

A similar device is known from European patent description EP 0645309. The idea here is to cut off the upper part of a box up to a given height and then to close the reduced box with an exactly-matching cover.

A device making boxes of given sizes by Packsize International (http://www.pac5ize,com) is also known. Basing on in-hand orders a machine can make custom-made blanking dies out of a long cardboard tape. Due to this feature one can make different-shaped cartons adjusted to packed goods with no necessity of storing them in various shapes and sizes.

There are many market-available cartoning machines that form packages from cardboard blanking dies. They offer a box forming section, manual or automated goods inserting section and a box closing section. Catoning machines are introduced on production lines where we deal with the same product and a regular box size.

According to the invention a box-forming machine is equipped with a product-packing station in which there is a canal fitted with a continuous cardboard gutter and limiting separators on both sides creating one-box space. it also has a side-forming station equipped with a set of knives, tools to create folding lines and pistons to bend package's flaps and tools connecting package's flaps as well as a station that closes the package with a cardboard cover. A machine has a station to form a continuous cardboard gutter equipped with rib-making rolls in place of bending lines and a system of guideways making a cardboard gutter with a cover out of flat tape.

The way of forming packages is that a solid material package, best cardboard, is formed from a continuous tape of packing material from which a continuous gutter in a canal is made. Separators are inserted into a gutter, !n insertion place a cut is made to form separate packages and to create end sides of a package.

The invention based solution allows to adjust package's volume to inserted goods' volume.

All operations of forming and closing cardboard are done automatically which increases the whole packing process efficiency.

Material used to form a package is fully-used which reduces potential losses.

An invention is presented on a picture where fig.l represents an outlook of a complete device armed with safety guards. Fig.2 represents a station making folding lines and forming rectangular gutter from packing material and a product-packing station. Fig.3 represents a station forming package's sides. Fig.4 represents upper-cover and upper-flaps closing station. Fig.5 represents action elements to form package's sides where a set of knives has been turned to view details better. Fig.6 represents other details of small elements. Fig.7 represents components of a package being made. Fig.8 represents an alternative way of making elements of the package's side-forming station.

A device comprises of a cardboard storage place 1, a cardboard rectangular gutter forming station 2, a packing product station 3, a station forming final sides of a package 4 and a station to close a cover and upper-flaps 5.

A cardboard storage place 1 has a scroll of a long cardboard strip made into a roll 6. In a gutter forming station 2 there are reels g5, g6, g7, g8 making ribs z5, z6, z7, z8 along cardboard gutter bending lines. In a product-packing station 3 there is a rectangular canal 7. !t has a drive system moving cardboard gutter allowing to move it along its axis. Above canal 7 there is a cover 8 with a cut over a cardboard gutter enabling goods and separators 9 to be inserted into a gutter. Those separators limit the side space of a single package 10.

In sides-forming station 4 there is a knives gantry 11 which moves vertically along a desk's guideways 12. Along gantry 11 there is horizontal movement of a left set of knives 13 and a right set of knives 14 in perpendicular direction to a cardboard gutter axis.

Between sets of knives there is a catcher 15 which enables positioning of separator 9 towards a station. Catcher 15 has a hook 16 which enables the hold of separator 9. Catcher 15 moves in a vertical direction along a rotating platform 17. Under a knives gantry 11 on both sides of canal 7 there are side pistons folding end side flaps of a package kl and k3 upper pistons left 19 and right 20 together with lower pistons left 21 and right 22.

Among side pistons under canal 7 there is an inner piston 24 folding end bottom flaps k2 with a knife n2.

Left set of knives 13 comprises of n3, n4, n5, n6, n7 knives and is making cuts on the upper cover and its adhering package side c3, c4, c5, c6, c7.

Right set of knives comprises of nl, n8 knives and is making cuts on the other side of a package cl, c8.

There are sticking out humps on sets of knives gl, g3, g4 which make ribs in cardboard where side flap foldings zl, z3, z4 appear.

Flaps-folding side pistons 19,20,21,22 have appropriate indentations enabling sets of knives 13 and 14 to enter them.

Side lower pistons 21 and 22 have glue dispensers 23 positioned on a piston's side and bottom.

A solution has been introduced which doses glue to both adjoining surfaces which improves the quality of connection.

Next in an upper-flaps closing station 5 there are glue dispensers 25. In the next part of station 5 there is a rotating platform 26 to close the upper lid k5 equipped with a rotating platform 27 turned by rams 28 and used to close the flap of upper lid k6.

Behind a rotating platform 26 at the bottom of a cardboard-providing canal there is a pulled-out glue dispenser 30.

Next to a glue dispenser 30 there is a rotating platform 29 to close the end upper flap k4.

In alternative embodiment a knife n6a making a cut c6 between the end upper flap k4 and an end side flap k3 is attached to the top of the upper left piston 19a. This positioning allows to make a cut c6 from an inner angel between an upper lid k5 and a package's side k7. Side lower pistons 21a and 22a have pull-out rolls 31 to make folding lines 22 for end lower flaps k2 package.

In alternative embodiment a sides-forming station is situated on a moving platform which moves along with a mobile cardboard gutter.

Owning to this one can move a cardboard gutter with a stable speed without any stops which increases packing comfort in a packing station.

In yet another embodiment a package's storage form might appear as a long tape made into a harmonica like bundle.

A machine's working cycle begins when a separator 9 moving together with a continuous cardboard gutter reaches a side-forming station 4. A separator is disabled by a hook 16 in a gripper 15 and a cardboard gutter is stopped. Gantry of knives 11 lowers a set of knives 13 and 14 in between cardboard gutter sides. At the process of lowering a left set of knives 13 makes cuts c4 an c5 and folding lines z4 on a package's cover. When gantry 11 is in a lower position sets of knives 13 and 14 move sides making cuts cl, c3, c6, c7, c8 and zl, z3 foldings on a package's sides. Sets of knives 13 and 14 move back again and together with gantry 11 move up leaving a cardboard gutter. Next up and above a package sets of knives 13 and 14 move side again to allow releasing separator 9. Side pistons 19,20,21,22 move deep into a cardboard gutter folding end side flaps kl and k3. Bottom piston 24 lifts itself up to a medium position and makes a cut c2 between end lower flaps k2. Lower side pistons 21,22 slide out and
