Abstract
Description
- The present invention relates to a machine for packaging pourable food products.
- Machines for packaging pourable food products, such as fruit juice, wine, tomato sauce, pasteurized or long-storage (UHT) milk, etc., are known in which the packages are formed from a continuous tube of packaging material defined by a longitudinally sealed web.
- The packaging material has a multilayer structure comprising a layer of paper material covered on both sides with layers of heat-seal plastic material, e.g. polyethylene, and, in the case of aseptic packages for long-storage products, such as UHT milk, also comprises a layer of barrier material defined, for example, by an aluminium film, which is superimposed on a layer of heat-seal plastic material and in turn covered with another layer of heat-seal plastic material eventually defining the inner face of the package contacting the food product.
- To produce aseptic packages, the web of packaging material is unwound off a reel and fed through an aseptic chamber in which it is sterilized, e.g. by applying a sterilizing agent such as hydrogen peroxide, which is later vaporized by heating and/or by subjecting the packaging material to radiation of appropriate wavelength and intensity. The sterilized web is then folded into a cylinder and sealed longitudinally to form, in known manner, a continuous, vertical, longitudinally sealed tube. The tube of packaging material, in other words, forms an extension of the aseptic chamber, and is filled continuously with the pourable food product and then fed to a forming and (transverse) sealing unit for forming the individual packages and on which pairs of jaws grip and seal the tube transversely into pillow packs.
- The pillow packs are then separated by cutting the sealing portion between the packs, and are fed to a final folding station where they are folded mechanically into the shape of the finished packages.
- The forming process involves folding the packaging material along crease lines formed beforehand as part of the material manufacturing process.
- The material manufacturing process typically comprises laminating steps to produce the various layers of which the material is formed; a number of printing steps to print graphics or designs periodically recurring along the material with a pitch equal to the length of material used to produce each package; and the above-mentioned creasing step performed either on the finished material or only on a subset of material layers comprising at least the paper layer. Holes are also known to be formed in the paper layer before it is covered with a continuous layer of barrier material to form so-called "prelaminated" holes closed by the barrier material which ensures hermetic, aseptic sealing while at the same time being easily pierced. The holes in the paper layer may conveniently be formed using the same tool as for the crease lines, in which case, the barrier material is laminated afterwards.
- Packaging materials with prelaminated holes are used for aseptic packages with straws or opening devices, e.g. of the type comprising a hinged lid or screw cap.
- The various operations in the packaging material manufacturing process are performed using, as a register mark, an optical register code printed on the material in the course of the first printing step.
- The same code is normally also used on the forming machine to control feed of the material through the various work stations. More specifically, as is known, a so-called "design correction" device acts on the packages being formed to variably "draw" the material in the feed direction and ensure that the mechanical forming operations are performed in register with the design on the packages.
- Material manufacturing tolerances, however, may result in position errors of the optical register code with respect to the crease lines, so that frequent manual adjustment of the design correction device (based on the optical register code) is required to prevent the forming members from interacting with the material incorrectly with respect to the crease lines.
- On known packaging machines, the angular position of the tube of packaging material may vary, in use, with respect to the desired angular position, on account of the lateral edges of the web not being perfectly straight, and the effect produced by the pairs of jaws successively striking the tube.
- As this may have negative effects on the quality of the longitudinal and transverse seals, and on the accuracy with which the packages are formed, known machines are provided with devices for manually adjusting the angular position of the tube. Such devices, however, are relatively time-consuming, and may involve shutting down the machine with consequent loss of production. Systems have also been proposed for automatically adjusting the angular position of the tube of packaging material, but call for the use of a dedicated sensor to determine the position of the longitudinal seal.
- It is an object of the present invention to provide a machine for packaging pourable food products, designed to solve the aforementioned problems typically associated with known machines.
- According to the present invention, there is provided a machine for packaging pourable food products in packages formed from a continuous web of packaging material, said machine comprising a longitudinal folding unit for longitudinally folding said web to form a continuous tube; a forming unit having at least two pairs of jaws interacting cyclically with said tube to seal the tube along equally spaced transverse bands; and a control device for controlling the feed of said tube, and in turn comprising means for correcting the longitudinal position of said tube, and means for correcting the angular position of said tube; said packaging material comprising a design, and a series of crease lines to assist folding of the packaging material on said forming unit; characterized in that said control device for controlling the feed of said tube comprises detecting means for detecting the position of optically detectable elements formed on said material and in register with said crease lines; and means for controlling said means for correcting the longitudinal position of said tube and said means for correcting the angular position of said tube in response to respective longitudinal and transverse position errors of said optically detectable elements detected by said detecting means.
- Controlling the position of the tube of packaging material on the basis of a position reference in register with the crease lines prevents any manufacturing tolerances, which might result in the crease lines not being perfectly in register with the design, from impairing sealing quality and the forming process.
- Successive operations on the package employing the edges of the package as a reference, as when applying opening devices over the holes, are also performed correctly, by formation of the package being controlled on the basis of a position reference in register with the crease lines.
- The present invention therefore provides for improving finished package quality and reducing manual adjustment of the machine.
- In a preferred embodiment of the present invention, the position of the prelaminated holes in the material is used as an element for detecting the position of the tube of packaging material; the position of the holes is compared with a memorized reference position; and any longitudinal and transverse errors are used to correct the feed of the material and the angular position of the tube respectively.
- Using the prelaminated holes as position detecting elements enables both the longitudinal and angular position of the tube to be controlled using one sensor.
- A preferred, non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a front view of a packaging machine featuring a packaging material feed adjusting device in accordance with the present invention;
- Figure 2 shows a view in perspective of a station for supplying and folding the packaging material;
- Figure 3 shows a schematic side view of a forming station on the Figure 1 machine;
- Figure 4 shows a diagram of the packaging material feed adjusting device according to the invention;
- Figure 5 shows a portion of packaging material.
-
- With reference to Figures 1 to 3,
number 1 indicates as a whole a packaging machine for producing packages of a pourable food product, such as pasteurized or UHT milk, fruit juice, wine, etc. - In particular,
machine 1 provides for producing aseptic sealed packages of a pourable food product from atube 2 of heat-seal packaging material 4, in turn formed by longitudinally folding and sealing aweb 3 of packaging material. - Material 4 (Figure 5) conveniently comprises a
layer 4a of paper material; and alayer 4b of barrier material defined, for example, by a sheet of aluminium.Layers Layer 4a of paper material comprises a succession ofholes 5 formed prior to laminatinglayer 4b; and a series of crease lines 13 (Figure 4) for assisting folding of the material when forming the packages, and which periodically recur with a pitch P equal to the distance between the holes and to the length of the portion ofweb 3 required to produce each package.Holes 5 andlines 13 are conveniently formed on the same fixture so that they are perfectly in register with each other. -
Layer 4b is whole atholes 5 to ensure hermetic, aseptic sealing of the package until it is opened; and pull-off or other types of opening devices (not shown) are later fitted overholes 5. -
Material 4 also comprises adesign 14 defined by a succession of graphics periodically recurring with pitch P and each comprising anoptical register code 15.Design 14 conveniently also comprises awhite area 15a surrounding each hole 5 (Figure 5). -
Web 3 ofpackaging material 4 is unwound off a reel (not shown) and fed by known guide roller devices (not shown) through a known sterilizing unit (not shown) to a topaseptic chamber 6 ofmachine 1, which communicates with the sterilizing unit and through whichweb 3 is fed along a horizontal path P1.Web 3 is then diverted downwards by a roller 7 - forming part of a system of rollers, one of which is powered - and is fed downwards along a vertical path P2 extending inside a vertical chamber ortower 8. - Inside
tower 8,web 3 is folded longitudinally into a cylinder to formtube 2, which has a longitudinal axis A parallel to path P2 and is sealed longitudinally by asealing device 10 and by means of a known heat-seal strip not described in detail. Tube 2 is filled continuously with the food product by means of a known filling device 11 (not described in detail), and is fed to a known formingunit 12 described below only as regards the parts pertinent to the present invention. - More specifically,
machine 1 comprises afolding unit 9 for longitudinally foldingweb 3 to formtube 2, and which is defined by a number of knownfolding assemblies tower 8 and interacting withweb 3 to fold it gradually into a cylinder and overlap the opposite lateral portions of web 3 (Figures 1 and 2) to form the tube of packaging material. -
Assemblies cylindrical folding rollers web 3 of packaging material being folded. As it is fed through the passages, the web passes from an open C shape defined byfolding rollers 21 offolding assembly 16, to a substantially circular shape defined byfolding rollers 23 offolding assembly 18. - The axes of
rollers folding assemblies folding rollers 22 ofassembly 17 are fitted to a C-shaped supportingplate 24 connected to the structure ofmachine 1 so as to be angularly adjustable about axis A to adjust the angular position oftube 2 being formed with respect to axis A. - The rotation of
plate 24 is controlled by anactuator 25 via a transmission, e.g. a screw-nut screw,mechanism 26. - The speed at which
web 3 is fed throughfolding assemblies assemblies 35, 35', and is influenced by anelectric motor 27 poweringfolding roller 7. - Once sealed longitudinally,
tube 2 is fed to formingunit 12. -
Unit 12 comprises a supportingstructure 33 defining twovertical guides 44 arranged symmetrically with respect to a longitudinal vertical mid-plane α of the unit through axis A, and the respective axes of which lie in a transverse vertical mid-plane τ ofunit 12. Axis A therefore defines the intersection of planes α and τ. -
Unit 12 comprises, in known manner, two formingassemblies 35, 35' movable vertically alongrespective guides 44 and interacting alternately withtube 2 of packaging material to grip and heat seal cross sections of the tube. - Since
assemblies 35, 35' are symmetrical with respect to plane α, only one (assembly 35) is shown in detail in Figure 3 and described below. In the accompanying drawings, the corresponding parts ofassemblies 35, 35' are indicated using the same reference numbers. - With reference to Figures 1 and 3,
assembly 35 substantially comprises aslide 36 movable alongrespective guide 44; and twojaws 37 hinged at the bottom to slide 36, about respectivehorizontal axes 38 parallel to and symmetrical with respect to plane τ, so as to open and close substantially "bookfashion". - More specifically, each
jaw 37 comprises amain control body 39, which is substantially in the form of an appropriately ribbed quadrangular plate (Figures 1 and 3), extends along a work plane β ofjaw 37 containingrespective axis 38, is hinged close to its bottom side to slide 36, and comprises arespective control arm 40 projecting from a face ofbody 39 facing away from plane β. -
Jaws 37 also comprise respective supportingarms 41, which are fitted to the top ends ofrespective bodies 39 ofrespective jaws 37, and project towards and beyond plane α, in a direction parallel torespective axes 38 and substantially along respective work planes β, so as to be located on opposite sides oftube 2. - The projecting portions of
arms 41 are fitted with respective bar-shaped sealing elements 42, 43 (Figure 3) which interact withtube 2, and which may be defined, for example, by an inductor for generating current in the aluminium layer of the packaging material and melting the thermoplastic layer as a consequence of the Joule effect, and by a mating pad against which to griptube 2 to the required pressure. - The reciprocating movement of
slides 36 and the opening/closing movement ofjaws 37 are controlled in known manner (not described) by pairs of vertical rods (not shown) in turn controlled by rotary cams or servomotors. -
Jaws 37 are movable between a closed position in whichrespective sealing elements grip tube 2, and a fully-open position. - At the transverse sealing step,
tube 2 is heat sealed along equally spaced transverse bands 45 (Figure 4). - Over
respective sealing elements arms 41 ofjaws 37 support respective packagevolume control tabs 46 having a C-shaped cross section open at the front, and which cooperate with each other, after the transverse sealing operation performed byelements tube 2 into a rectangular-section shape. - The above forming step (Figure 4) produces "pillow" packs 47, each comprising a
main portion 48 of the same shape and volume as the finished package; andtransition portions 49 connectingmain portion 48 to respective adjacent sealingbands 45, and defined laterally by substantially triangular faces 50. - One of
jaws 37 comprises, in known manner, twofolding tabs 54 for controlling, together with foldingroller 7, the longitudinal feed oftube 2 through formingunit 12. - Folding tabs 54 (Figures 3 and 4) are located on either side of
tube 2, are symmetrical with respect to axis A and adjacent totube 2, rotate about respective axes perpendicular to plane β, and are rotated in opposite directions by a known design correction device 51 - active at the forming step - so as to act on lateral faces 50 oftransition portions 49 of the pillow packs and exert variable pull ontube 2. -
Device 51 comprises, for example, a variable-geometry or variable-position cam 52, shown purely schematically in Figure 4, which interacts with acam follower 53 carried byjaw 37 and connected totabs 54 by atransmission mechanism 55 also shown purely schematically. Examples of such a control device are illustrated in Italian Patent Application n. MI97A-002473 and in European Patent Application n. 99830715.1 filed by the present Applicant. - The travel of
tabs 54, and therefore the amount of pull exerted ontube 2, is adjustable, as described in detail later on, by means of anactuator 56 acting, for example, on the position ofcam 52. -
Actuator 25 controllingtube folding assembly 17,electric motor 27 poweringfolding roller 7, andactuators 56 ofdesign correction devices 51 ofrespective assemblies 35, 35' form part of adevice 60 for controlling the feed oftube 2 of packaging material. In addition,device 60 also comprises a conventional firstoptical sensor 61 for reading theoptical register code 15 printed onmaterial 4; a secondoptical sensor 62 for detecting the position ofholes 5; and acontrol unit 63 connected at the input tosensors motor 27. - The second
optical sensor 62 is conveniently defined by a video camera, e.g. a CCD type, which "reads" a portion ofmaterial 4 atholes 5. To avoid acquiring and processing an excessive amount of data,first sensor 61 is used to generate an enabling signal I1, which changes state in response to detection of acode 15 and is supplied to controlunit 63 to read-enable the second optical sensor.Sensor 62 is thus only read-enabled at eachhole 5 or at one of every N number ofholes 5, and supplies controlunit 63 with signals I2 indicating the position ofholes 5 and relative, for example, to a conventionally coded pixel matrix. -
Control unit 63 compares the position of the detectedhole 5 with a memorized reference position (Figure 5) and calculates a longitudinal position error E1 oftube 2, and a transverse position error E2 ofhole 5, obviously correlated to the twist angle oftube 2. -
Control unit 63 generates a signal O1 for controllingelectric motor 27; signals 02 (identical) for controllingactuators 56; and a signal O3 for controllingactuator 25. Signals O1 and O2 are correlated in conventional manner with value E1, and signal O3 with value E2. - In actual use, the speed at which
material 4 is supplied tofolding assemblies unit 12 is determined bymotor 27 controlled bycontrol unit 63. Being known and partly deducible from the above description, operation ofassemblies unit 12 is not described in detail. - If the longitudinal position of
tube 2 is correct, i.e. if the absolute value of E1 is below a predetermined threshold value, the control unit maintains a constant speed ofmotor 27. Conversely, in the presence of an error E1, the supply speed ofmaterial 4 is corrected bycontrol unit 63 appropriately modulating signal O1. If the resulting correction is not sufficient, in addition tomotor 27,control unit 63 also acts ondesign correction device 51 by appropriately adjusting, by means of signal O2, the amount of pull exerted by foldingtabs 54. According to the present invention, the above controls, in themselves known, are performed on the basis of position errors of holes 5 - which, as stated, are in register with crease lines 13 - and not on the basis ofoptical code 15 in register with and forming part ofdesign 14. - In a preferred embodiment of the present invention, signal I1 of
first sensor 61 is only used to generate a "read window" in whichsecond sensor 62 actually reads the position ofmaterial 4 based on the position of ahole 5 at a given instant, and supplies controlunit 63 with a signal I2 indicating the matrix of pixels detected. Thewhite area 15a surrounding eachhole 5 simplifies the reading. - Another important characteristic of the present invention is that signal I2 is also used to calculate the transverse position error of the hole, and so correct twisting of
tube 2 by means of foldingassembly 17. More specifically, in response to a transverse position error E2,control unit 63commands actuator 25, by means of signal O3, to rotatefolding assembly 17 in one direction or the other depending on the error sign. This control is also performed on the basis of the position ofholes 5 as opposed tooptical code 15. - Clearly, changes may be made to
machine 1 as described herein without, however, departing from the scope of the invention. In particular,second sensor 62 may be replaced by any type of sensor, e.g. defined by a linear succession of photosensitive elements extending crosswise to the feed direction oftube 2, to reconstruct the position ofholes 5 by scanning the area of the hole as the material is fed forward, as opposed to picking up an instantaneous image. Moreover, different position references may be used, providing they are in register with crease lines 13.
