1. Technical Field
The present application relates to a method of shrink wrapping packs of containers and a shrink-wrapping arrangement for performing the method.
2. Background Information
Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.
The present application relates to a method for heat-shrinking a shrink wrap film onto packs, whereby the heat-shrinking of the shrink wrap film of packs being moved a transport track is performed using a hot, gaseous media, for example hot air. The hot, gaseous medium forms at least one jet that is moved in conjunction with the respective pack by control action during heat-shrinking. The present application also relates to an apparatus for the heat-shrinking of a shrink wrap film to packs, having at least one jet of a hot, gaseous medium, for example having at least one jet of hot air, having at least one transport track on which the packs are moved during the heat-shrinking of the shrink wrap film, and having at least one discharge or nozzle opening for emitting the at least one jet of the hot, gaseous medium. The at least one jet of the hot, gaseous medium is moved in conjunction with the respective pack by control action during heat-shrinking for performing method of the present application.
Different types of packs, including for example in the form of trading units comprising multiple packaging units, are held together by means of shrink wrap film.
Packaging units include e.g. packs filled with a product and sealed, such as bottles and cans, but also product-filled packs made of a single or multi-ply sheet material, etc.
To create packs in the form of trading units, multiple packaging units are assembled into a trading unit group, which is then wrapped in shrink wrap and the shrink wrap exposed to a hot, gaseous medium, i.e. in practice heat-shrunk onto the trading unit group using hot air so that the packaging units are joined together to form the trading unit.
Heat-shrinking of the shrink wrap film is performed by moving the packs or trading unit on a conveyor through an apparatus configured as a shrink tunnel.
It is not always possible to heat-shrink the shrink wrap film to create crease-free packs, which are increasingly required to satisfy the more exacting requirements of consumers.
An object of the present application is to describe a method that can increase the effectiveness of the heat-shrinking of shrink wrap films onto packs and by means of which it is also possible to produce crease-free packs when heat-shrinking the shrink wrap film.
A method for achieving this object is disclosed as a method for the heat-shrinking of a shrink wrap film onto packs, whereby the heat-shrinking of the shrink wrap film of packs being moved a transport track is performed using a hot, gaseous media, for example hot air. The hot, gaseous medium forms at least one jet that is moved in conjunction with the respective pack by control action during heat-shrinking.
An apparatus for performing the method is the subject of an apparatus for the heat-shrinking of a shrink wrap film to packs, having at least one jet of a hot, gaseous medium, for example having at least one jet of hot air, having at least one transport track on which the packs are moved during the heat-shrinking of the shrink wrap film, and having at least one discharge or nozzle opening for emitting the at least one jet of the hot, gaseous medium. The at least one jet of the hot, gaseous medium is moved in conjunction with the respective pack by control action during heat-shrinking.
A general feature of the present application lies in the fact that the at least one jet of the hot, gaseous medium, preferably the at least one hot air jet, used to heat-shrink the shrink wrap film, is moved in conjunction with the respective pack during the shrink wrap operation so that this jet is constantly aimed at the respective pack until the conclusion of said shrink wrap operation.
In a preferred embodiment of the present application, the at least one jet of the hot, gaseous medium is moved in conjunction with the respective pack such at this jet is aimed exclusively at one heat-shrink port during the shrink wrap operation.
This is created by leaving at least one lateral opening, for example, when wrapping the pack with the shrink wrap film, which opening remains as a heat-shrink port through which the at least one jet of hot, gaseous medium enters the wrapper enclosing the pack and formed by the shrink wrap, thus causing the shrink wrap to shrink from the inside out.
The at least one jet is moved in conjunction with the pack by control action so that it enters the heat-shrink port as close to center as possible and so that this jet is not pierced or transected by overhanging shrink wrap or shrink wrap edges/corners.
The at least one jet of the hot, gaseous medium aimed into the heat-shrink port causes the shrink wrap film on the at least one packaging unit to initially inflate due to a back pressure and lift off of the pack so that the shrink wrap film can enclose the at least one packaging unit crease-free during the shrink wrap operation.
The controlled movement of the at least one jet of the hot, gaseous medium in conjunction with the respective pack can be accomplished in a variety of ways, for example by moving at least one nozzle opening for discharging the hot, gaseous medium in conjunction with the respective pack, or by providing a nozzle arrangement having a plurality of controlled discharge or nozzle openings for the hot, gaseous medium, and which arrangement is moved along the transport path on which the pack is moved during the shrink wrap operation.
The nozzle openings are activated and deactivated by computer control such that only one or multiple nozzle openings at that point along the transport path where a pack is located are activated for the discharge of the jet of hot, gaseous medium so that the jet of the hot, gaseous medium emerging from the at least one activated nozzle opening enters the heat-shrink port of the respective pack.
Activation and deactivation of the nozzle openings is by means of controlled slide valves or orifices.
Also possible is the provision of a plurality of individually-controlled nozzles comprising the nozzle openings.
Further embodiments of the present application are disclosed below.
The above-discussed embodiments of the present invention will be described further herein below. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
Possible embodiments of the present application are described in greater detail below illustrated with the accompanying drawings, in which:
In the figures, 1 are trading, shipping, or multi-pack units, each comprising multiple packaging units 2, namely in the embodiment shown a total of six packaging units in the form of bottles, a carrier 3 for these packaging units and a packaging or shrink wrap film 4 heat-shrunk onto the packaging units 2 and the carrier 3 and thus the trading unit 1. Other packaging units could be containers, cans, or boxes.
In the interest of simplifying the view, the packaging units 2 of the trading unit 1 are shown together in
To form the trading unit, the shrink wrap film 4 is wrapped around the trading unit comprising the packaging units 2 and the carrier in an apparatus not shown here but known to a practitioner skilled in the art so that the shrink wrap film encloses each trading unit 1 at the top and the bottom but initially leaving each trading unit 1 open on two opposing sides, forming a so-called heat-shrink port 5, which port is enveloped by a film overhang 4.1.
Overlapping ends of the shrink wrap film 4 created during wrapping are located on the underside of the carrier 3 facing away from the packing units 2.
The shrink wrap film 4 is heat-shrunk using lateral hot air jets A, each of which is aimed at one heat-shrink port 5. The resulting back pressure slightly raises the shrink wrap film 4 from the packaging units and also laterally away from the carrier 3 by approximately twenty to thirty centimeters, for example. Among other things, this essentially ensures or promotes that the energy input by the hot air is applied to the inside of the shrink wrap film 4 for optimal heat-shrinking of this film onto the trading unit 1. To achieve crease-free or substantially crease-free heat-shrinking of the shrink wrap film 4, it is also important that the respective hot air jet A coming from the side is aimed as closely as possible, or substantially closely, to the center of the heat-shrink port 5 and not at the edges surrounding the heat-shrink port 5 or at the film overhangs 4.1.
The shrink wrap film 4 is sealed on the underside of the trading unit 1 or the carrier 3 by means of hot air jets aimed at this underside, as is indicated by the arrows B in
The apparatus 6 is configured as a shrink tunnel, through which the trading unit 1 wrapped in shrink wrap film 4 is passed, in one possible embodiment on a conveyor belt 7 in a horizontal direction of transport C.
In the embodiment shown, the apparatus 6 is configured as a two-track unit with two parallel or virtually parallel conveyor belts.
A nozzle arrangement 8 and 9 is located on both sides of the transport path of each conveyor belt 7.
In the embodiment shown, each nozzle arrangement comprises a closed distribution channel 10 extending in the direction of transport C, which channel is connected to a hot air source not shown in the figures and which channel extends in the vertical direction to a height that is at least equal to the maximum height of the trading unit 1 to be processed with the apparatus 6.
The outer nozzle arrangements 8 have a plurality of discharge or nozzle openings 11 for hot air on that side of the distribution channel 10 facing the respective conveyor belt, arranged in a vertical plane and extending in the direction of transport C. The distribution channel 10 of the nozzle arrangement 9 has these nozzle openings 11 on both sides, each of which is arranged in vertical planes and extends in the direction of transport. The discharge openings 11 are distributed such that they form multiple vertical rows R1-Rn, in which the nozzle openings 11 are tightly packed and arranged in close sequence in the vertical direction.
There is one slide valve 12 for each row R1-Rn or each group of two or more than two rows, which slide valve 12 is controlled by an independent actuator, e.g. in the form of pneumatic cylinder, and can be moved so that the nozzle openings 11 are closed by the slide valve 12 when the same is in one state and open when the slide valve is in the other state.
By actuating the individual slide valves 12 via an electronic controller, e.g. via a computer, the nozzle openings 11 of the individual rows R1-Rn can be opened and closed synchronously with the motion of the conveyor belts 7 so that the hot air jet A aimed at the trading unit 1 from the side moves in conjunction with this trading unit 1 or the respective trading unit until the conclusion of the shrink wrap operation without the edges and overhangs of the shrink wrap film 4.1 surrounding the heat-shrink port intersecting the respective hot air jet A, but rather the hot air jet is directed from the side to the center of the open heat-shrink port.
Control of the slide valves may be performed by means of sensors, for example, that deliver a signal corresponding to the respective position of the trading unit 1 and/or by allowing for the transport speed of the conveyor belts 7, which is also measured by sensors.
To enable the device 6 to also process trading units 1 of different heights, means are provided by which the height of the rows R1-Rn active during the heat-shrink operation can be adjusted to the height of the trading unit 1. For example, this is made possible by providing horizontally mobile slide valves 13 in addition to the slide valves 12, by means of which slide valves 13 a certain number of nozzle openings 11 of each row R1-Rn can be activated or deactivated. It is also possible to subdivide the respective distribution chamber 10 of the nozzle arrangements 8 and/or 9 into multiple subchambers extending in the direction of transport C and separated from one another, which can then be activated or deactivated to adjust for the height of the trading unit 1, i.e. to match the format.
Instead of nozzle openings 11 actuated via slide valves 12 and/or 13, it is also possible to configure each nozzle opening as an individually controlled hot air nozzle, so that these individual nozzles are opened and closed by computer in such a manner that the hot air jets A aimed from the side at the trading unit 1 or its heat-shrink port move in conjunction with the trading units 1 in the direction of transport C, and the number and position of activated nozzles correspond to the position and shape and/or size of the trading unit 1 or the heat-shrink ports on these trading units.
Provided above the carousel system 14 or above a support surface for the trading unit formed by this carousel system are heat-shrink bells 15, which are moved in conjunction with the trading units on or in the carousel system 14 and which are each connected by means of a hose or a tubular connection 16 to a hot air source 17 arranged in the center of the carousel system 14.
The heat-shrink bells 15 are configured as shown in
The trading units 1 with the shrink wrap film 4 are delivered to the apparatus 6a via a conveyor 20 so that each trading unit 1 on the carousel system 14 is arranged under a heat-shrink bell 15, and the heat-shrink ports 5 are radially outward or radially inward relative to the axis of rotation of the carousel system 14.
Because the heat-shrink bells 15 move in conjunction with the carousel system 14 and the trading units 1 arranged thereon, it is essentially ensured or promoted that the hot air jets A blow on the center of the heat-shrink ports 5 during the heat-shrinking.
After heat-shrinking of the shrink wrap film 4, the trading units 1 on the carousel system 14 are lowered and are then transferred in the lowered or descended position to the conveyor 21 and transported away.
The apparatus 6b differs from apparatus 6a from
These are configured like the nozzle arrangements 8 and 9, but are semicircular in shape.
The outer nozzle arrangement 23 faces inward and the inner nozzle arrangement 24 faces outward; both have a plurality of controlled nozzle openings 11.
The nozzle openings 11 are, in turn, arranged sequentially in multiple vertical rows in the direction of transport D of the carousel system 22, and by means of slide valves corresponding to the slide valves 12 and 13 can be actuated synchronously with the motion of the trading units 1 on the carousel system 22 so that the hot air jets A discharged through the nozzle openings 11 are precisely or generally aimed as closely as possible to the center of the respective heat-shrink port 5, and move in conjunction with the trading units 1 to essentially ensure or promote this.
The slide valve corresponding to the slide valves 13 enables adjustments for various formats, i.e. an adjustment for the height of the trading units 1.
The nozzle openings 11 can also be configured as individually controlled single nozzles or hot air nozzles, which are then controlled so that the hot air jets A move as required or desired in conjunction with the movement of the trading units 1 on the carousel system 22, with control by means of sensor signals defining the position of the trading units 1 on the carousel system 22.
Following the heat-shrink operation, the trading units 1 are lowered and are transferred in this lowered position to the conveyor 21.
The trading units 1 are delivered to the apparatus 6c via the conveyor 20 and removed from the apparatus 6c via the conveyor 21 following heat-shrinking of the shrink wrap film.
Inside the apparatus 6c, each of the trading units 1 is carried upward in the vertical direction (arrow E) in one segment 26.1 of the transport track 26 and then carried together with the trading unit carrier 27 on which it is standing downward in the vertical direction (arrow F) in the segment 26.2 of the transport track 26 to the exit of the apparatus 6c.
Nozzle arrangements 28 and 29, each with a plurality of controlled nozzle openings 11, are provided on two opposing sides of the transport track 26 for the lateral discharge of hot air jets A against the trading units 1 or their heat-shrink ports.
To this end, the trading units 1 are delivered to the apparatus 6c so that the heat-shrink ports 5 face the sides of the transport track 26 having the nozzle openings 11.
The nozzle openings 11 are controlled so that the lateral hot air jets A are aimed precisely or generally at the center of the heat-shrink ports 5 and move in conjunction with the movement of the trading units (arrows E and F).
This is achieved by the controlled movement of the slide valves, for example, which are moved horizontally to open and close the nozzle openings 11 synchronously with the movement of the trading units 1, i.e. parallel or virtually parallel thereto, so that only or mostly only those nozzle openings 11 corresponding to the location of a heat-shrink port of a trading unit are opened.
In this embodiment, the nozzle openings 11 are arranged sequentially in multiple vertical rows in the horizontal direction, whereby the nozzle openings 11 in each row are closely spaced top-to-bottom and side-to-side.
Adjustments for different horizontal dimensions of the trading units are performed by means of additional slide valves that can be actuated in the vertical direction to open or close the nozzle openings 11, for example.
This embodiment can also include nozzle openings 11 configured as individually controlled single or hot air nozzles that are actuated synchronously with the movement of the trading units 1 by means of an electronic controller such as a computer.
The present application was described above with reference to one possible embodiment.
It will be understood that numerous modifications and derivations are possible without departing from the teaching on which the present application is based.
For example, it was assumed above that each trading unit 1 has a carrier 3.
It is understood that this is not required.
Trading units 1 can also solely or mostly comprise the packaging units 2 and the shrink wrap film 4 holding these units together.
