Definitions

  • the invention generally relates to packaging technology. More particularly, it is related to a packaging material arrangement, a roll-fed packaging machine, a system and methods related thereto that provide improved control during the course of producing packages by the roll-fed packaging machine.
  • a well-known packaging material to use in this context is a carton-based laminate.
  • such laminate can comprise a carton-based layer for providing rigidity and plastic layers for protecting the carton-based layer from moisture as well as for preventing oxygen and unwanted microorganisms to reach the food product.
  • This type of packaging material is by way of example marketed by Tetra Pak TM .
  • a common approach is to produce packaging material in factories, sometimes referred to as converting factories, and distribute the packaging material to dairies or other food production facilities. Most often, once produced and printed, a web of packaging material is rolled up on a reel such that the packaging material can be securely and efficiently transported to production sites, i.e. the dairies or other food production facilities.
  • ASU automatic splicing units
  • each reel may be provided with an RFID tag or similar and the packaging machine may be provided with a tag reader such that the RFID tag can be read once the reel is received.
  • An advantage with this approach is that data stored on the RFID tag can be transmitted to the packaging machine. In this way, information about the packaging material can be provided to the packaging machine such that machine settings can be adjusted automatically.
  • QR codes Another known approach to improve the control during the course of transforming the web of packaging material into packages is to use QR codes or the like. More particularly, by having each sub-section of the web provided with a unique code, e.g. a QR code, these sub-sections can be traced throughout the packaging machine and also after the sub-sections have been transformed into packages, that is, downstream the packaging machine. In this way, by having increased information about where in the packaging machine the different sub-sections are placed at a given point of time, an increased understanding of the operation of the packaging machine is provided, which in turn provide for improved control.
  • a unique code e.g. a QR code
  • it is an object to provide a cost-efficient, but yet reliable solution for controlling the operation of a roll-fed packaging machine. More particularly, it is an object to provide more detailed information about the remaining number of packages that can be produced before the reel with packaging material has to be replaced by a new one.
  • a packaging material arrangement for a roll-fed packaging machine comprising
  • An advantage with the packaging material arrangement above is that by continuously determining the rotational position of the reel it is made possible to determine the number of sub-portions remaining on the reel at any given point of time. In this way, an operator of the packaging machine can be provided with more detailed information about the current status of the filling machine.
  • the pattern may be reel-specific such that the roll-fed packaging machine can identify the packaging material arrangement based on the pattern.
  • a reel-specific pattern may serve dual purposes; determining the rotational position, and identifying the reel.
  • the pattern may comprise a two-dimensional printed pattern.
  • the two-dimensional printed pattern comes with the advantage that the pattern can be provided at a relatively low cost.
  • using a two-dimensional pattern provide for that more information is made available via the pattern compared to a one-dimensional pattern, e.g. only radially extending lines, which provides for that more reliable measurements can be made.
  • the two-dimensional printed pattern may comprise a number of printed lines extending radially with respect to a center axis of the reel.
  • the package material may comprise a number of layers, wherein at least one of these layers is a cellulose-based layer.
  • a roll-fed packaging machine for producing packages filled with liquid food product.
  • the machine may comprise
  • the advantage with having the roll-fed packaging machine according to the second aspect is that the number of sub-portions remaining on the reel can continuously be determined.
  • the other advantages described above with respect to the first aspect also apply for this second aspect.
  • the packaging machine may further comprise a control device arranged to retrieve sensor output data from the sensor, to transform the sensor output data into a reel-specific code, to transmit a request for stored status data, pertaining to sub-positions of the web remaining on the reel, by transferring the reel-specific code to a database, and in response to the request, to receive the stored status data from the database.
  • a control device arranged to retrieve sensor output data from the sensor, to transform the sensor output data into a reel-specific code, to transmit a request for stored status data, pertaining to sub-positions of the web remaining on the reel, by transferring the reel-specific code to a database, and in response to the request, to receive the stored status data from the database.
  • the control device may further be configured to retrieve the sensor output data from the sensor as the web is unrolled by the web feeder, to determine rotational position data by determining the rotational position based on the sensor output data, and to determine a number of sub-portions rolled off based on the rotational position data, and to determine current status data being the stored status data deducted by the number of sub-portions rolled off since a point of time in which retrieving the stored status data from the database is initiated.
  • the control device may further be configured to detect that the reel is removed from the reel receiver, and, upon such detection, to transfer the current status data to the database together with a request to have the current status data set as the stored status data.
  • the control device may further be configured to request product information data, packaging material characteristics data, sealing settings data, machine settings data, transportation log data and/or storage log data linked to the reel-specific code from the database.
  • a system comprising the roll-fed packaging machine, a number of packaging material arrangements according to the first aspect, and a database holding stored status data for the number of packaging material arrangements.
  • the method may comprise
  • the pattern may be reel-specific and linked to a reel code, and the method may further comprise
  • a method for providing current status data pertaining to a number of sub-portions remaining on the packaging material arrangement according to the first aspect held by the roll-fed packaging machine according to the second aspect may comprise
  • a computer program product comprising instructions, which when the program is executed by the control device, cause the control device to carry out the steps of the method according to the fifth aspect.
  • first, second, etc. may be used herein to describe various elements or features, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.
  • a first peripheral section could be termed a second peripheral section, and, similarly, a second peripheral section could be termed a first peripheral section, without departing from the scope of the embodiments.
  • the first peripheral section and the second peripheral section are both peripheral section, but they are not the same peripheral section.
  • Fig. 1 is a general illustration of a packaging machine 100.
  • the packaging machine 100 comprises a transversal sealing station 114 for transversally seal and cut a tube 112 of packaging material into packages first 116.
  • the packaging material may comprise a paperboard layer, also referred to as carton or carton-based layer, and a plastic foil, sometimes referred to as plastic layer.
  • the plastic foil may be attached to the paperboard layer.
  • the transversal sealing station 114 may comprise a jaw system for continuously forming transversal sealings and cutting the tube into packages after the transversal sealings have been made.
  • the packaging machine 100 may be a stand-alone packaging machine, or part of a larger food packaging or processing pipeline.
  • the packaging machine 100 is a roll-fed packaging machine, the general principles of which will be described in the following.
  • the packaging material is provided on a packaging material arrangement 102, loaded into a reel receiver 118 of the packaging machine 100. From the arrangement 102, a web 104 of packaging material is formed.
  • the web 104 of packaging material may pass through a sterilization station 106 for removing or reducing a number of unwanted microorganisms from the web 104.
  • the sterilization may e.g. comprise a hydrogen peroxide bath, a Low Voltage Electron Beam (LVEB) device or any other suitable apparatus capable of meeting food safety regulations.
  • LVEB Low Voltage Electron Beam
  • the web 104 can be formed into the tube 112, e.g. by a longitudinal sealing station 110.
  • the tube 112 is formed by joining the two edges of the web 104 by a longitudinal sealing, LS.
  • the wording "longitudinal" herein relates to the longitudinal direction of the web 104 or tube 112 of packaging material.
  • the longitudinal direction coincides with a feeding direction, FD, in the packaging machine 100.
  • a food product, FP can be fed into the tube 112 via a product filling pipe 108, arranged at least partly inside the tube 112.
  • the filled tube 112 may thereafter reach the transversal sealing station 114.
  • transversal herein relates to a direction across the tube (i.e. a transversal direction, TD) once flattened in the transversal sealing station 114.
  • TD transversal direction
  • TS transversal sealing
  • the transversal sealing station has two main functions; 1) providing the transversal sealing, i.e. welding two opposite sides of the tube 112 together such that the product in a lower part of the tube 112 is separated from the product in the tube 112 placed upward the ultrasonic sealing system 300, and 2) cutting off the lower part of the tube such that the package 116 is formed.
  • the step of cutting off the lower part may be made in a subsequent step by a different piece of equipment, or by the consumer if the packages are intended to be sold in a multi-pack.
  • the package 116 After the package 116 has been formed, it may be folded in a folding station (not shown) thereby forming a finished food package.
  • the reel receiver 118 may be equipped with a reel ID reader 122 arranged to read a reel identification, ID, tag 120 on the reel 102.
  • the reel ID tag 120 may comprise information identifying the reel.
  • the reel ID tag 120 may comprise information indicative of a type of packaging material on the reel 102, material properties of the packaging material (e.g. thickness, material composition, etc.), a type of package to be formed by the packaging material, or packaging machine settings to be used.
  • the packaging machine 100 may further comprise a control device 126 comprising a processor 128 and a memory 130. The control device 126 may be configured to receive PM reel ID data extracted from the PM reel ID tag 120.
  • Fig. 2 illustrates, by way of example, the package 116 after a transversal sealing has been performed, but before it has been folded into the finished package. As illustrated, the package 116 is sealed in a transversal sealing section 200 spanning over two transversal ends of the package 116.
  • the package can be provided with a number of longitudinal crease lines 202a-c.
  • the crease lines 202a-c should be interpreted as indentions or weakening lines.
  • the crease lines 202a-c are typically embossed onto the packaging material during its manufacturing.
  • the crease lines 202a-c are designed to facilitate folding of the packaging material into its intended shape.
  • the tube 112 of packaging material may be, during a transversal sealing state, formed into a desired shape (e.g. a shape having a rectangular cross section).
  • the crease lines 202a-c may in this case be provided along the corners of the package to ensure that the package is formed accurately and consistently.
  • the package 116 comprises a first crease line 202a, a second crease line 202b, a third crease line 202c and a fourth crease line (not shown) corresponding to the four corners of the package 116.
  • the number of crease lines may be two or more depending on the type or shape of the package 116.
  • Fig. 3 illustrates by way of example the reel receiver 118 of the packaging material arrangement 102 in further detail.
  • the arrangement 102 comprises a reel 300 having a cylindrical inner surface 302, a cylindrical outer surface 304 and a ring-shaped side surface 306 on either side of the reel.
  • a shaft 308 of the reel receiver 118 is inserted into the reel 300 along a center axis (C-A) such that the web 104 can be unrolled from the reel 300 and fed into the packaging machine 100 along the feeding direction FD.
  • C-A center axis
  • the web 104 can comprise a number of sub-portions 310a-b, each of the sub-portions being arranged to be formed into one of the packages 116. As described above, crease lines may be used for facilitating the transformation from the web 104 into the packages 116.
  • the web 104 may be rolled off the reel 300 by using a web feeder 316, herein exemplified by two rollers. One of the rollers may be motor-driven and the other roller may be spring-loaded such that the web can be fed by the web feeder 316.
  • a sensor 314 arranged to read a pattern 312 of the ring-shaped side surface 306 can be placed on or in conjunction to the reel receiver 118.
  • a rotational position of the reel 300 with respect to the reel receiver 118 can be determined as the web 104 is unrolled.
  • the pattern 312 may be reel-specific such that which reel 300 that has been placed in the reel receiver 118 can be determined.
  • the reel can also be identified by using the same pattern 312.
  • the pattern 312 may come in different forms. It may be a printed pattern.
  • the printed pattern may be in the form of a one-dimensional bar code pattern as illustrated, but it may also be a two-dimensional printed pattern.
  • the pattern 312 may comprise lines radially extending with respect to the center axis C-A.
  • the pattern may also be a magnetic mark-based pattern.
  • magnetic particles can be provided in the reel 300 and the sensor 314 may be configured to register these magnetic marks as they are passing the sensor 314.
  • Sensor output data 328 generated by the sensor 314 may be transferred from the sensor 314 to the control device 318, which may be the same control device 126 as illustrated in fig. 1 or a separate control device.
  • the control device 318 may be an integral part of the packaging machine 100 or it may be external to the packaging machine 100. In the latter case, the sensor output data 328 may be transferred to the control device 318 via other pieces of equipment, e.g. data communication devices.
  • the control device 318 can comprise control circuitry 320 holding a processor 322, a transceiver 324 and a memory 326.
  • the control device 318 may also be communicatively connected to a database 330.
  • the database 330 may be an integral part of the packaging machine 100 or it may be placed remotely, i.e. outside the packaging machine.
  • An advantage with having the database 330 is that, in case the pattern 312 provides the reel-specific code, the concept of determining the number of remaining sub-portions on the reel 300 may also be applied on reels for which some, but not all, sub-portions have been unrolled. For instance, in case small batches of food packages are being produced, it may be that only 25% of the web 104 is used before this is stored away for later use. Having the reel-specific code and the database 330 provides for that the number of remaining sub-portions can be stored such that this information can be used when the reel 300 is re-introduced into the packaging machine 100.
  • the reel-specific code is also provided to the database 330.
  • the stored status data 334 may be provided from the database 330 to the control device.
  • the number of sub-portions 310a,b rolled off can be determined based on the sensor output data 328.
  • current status data 336 can be determined.
  • the current status data 336 can be fed to the database 330 when the reel 300 is removed from the packaging machine 100.
  • the concept can also be combined with other approaches to further increase the reliability. For instance, the concept may be combined with continuously weighing the reel as the web is unrolled to receive additional information on how much of the web 104 that is still on the reel 300.
  • a light-based sensor such as LIDAR, may be used for continuously determining a height reduction of a rolled-up web layer on the reel. Information obtained via such sensor may in combination with the information provided via the pattern 312 be used for providing the number of sub-portions left on the reel more accurately.
  • a method 400 for producing the packaging material arrangement 102 can comprise receiving 402 the reel 300, providing 404 the pattern 312 onto the ring-shaped side surface 306, e.g. by printing, and rolling up 406 the web onto the reel 300.
  • the method 400 may further comprise determining 408 the number of sub-portions 310a,b rolled up on the reel 300, and uploading 410 data pertaining to the number of sub-portions together with reel code to the database 330. Once uploaded, the data may be assigned as the stored status data 334.
  • the method 500 can comprise retrieving 502, by using the control device 318 of the packaging machine 100, the sensor output data 328 from the sensor 314 arranged on the reel receiver 118 of the packaging machine 100, wherein the sensor 314 is configured to read the pattern 312 of the ring-shaped side surface 306 of the reel 300 of the packaging material arrangement 102.
  • determining 504 by using the control device 318, rotational position data by determining the rotational position of the reel 300 based on the sensor output data 328, determining 506, by using the control device 318, the number of sub-portions 310a,b rolled off based on the rotational position data, and determining 508, by using the control 318, the current status data 336 by deducting the number of sub-portions from the stored status data 334.
  • the stored status data 334 pertains to the number of sub-portions remaining on the reel 300 at a time of retrieving sensor output data 328 is initiated.
