Definitions

  • ABSTRACT relates to a method of forming packages for articles by feeding layers of wrapping film along aligned paths in the same direction, causing these layers of wrapping film to adhere to each other at transversely extending positions spaced apart relatively to the direction of feed, and then opening out the two layers between two successive adhering regions so that the length of film between the adhering regions forms a tube.
  • the invention also includes a method and means whereby an opening device is introduced between the two layers of film whilst the film is in a flattened condition, and then the opennig deivce is acti vated to open out the tube to allow an article to be inserted therein.
  • 975 3,881,296 sum lBOF 1s METHOD AND APPARATUS FOR PACKAGING This invention relates broadly to the packaging of goods, and the invention is particularly useful in relation to shrink wrapping. In its broadest aspect however, the invention is concerned with the formation of a fiexible tube or open-ended bag of wrapping material into which an article or articles to be wrapped can be placed.
  • the shrink wrapping process requires the article(s) to be placed in a bag of heat-shrinkable plastics film and the invention can therefore be used to provide such a bag, but it is to be understood that the invention could also be used to provide packaging bags which do not require shrinking.
  • the article is then wrapped in a tube of film which is open at both ends, and a fresh barrier of film is created ready to receive the next article.
  • the film is considerably wider than the article, and hence the tube overhangs the article at both ends.
  • These overhanging parts of the tube can be gathered and sealed together so that the article is totally enclosed ready for the heat shrinking of the film wrapping, or the overlapping parts of the film can simply be allowed to contract on to the ends of the article if total enclosure by the wrapping film is not essential.
  • a method of forming a package for an article comprises feeding two layers of wrapping film in proximity to each other along aligned paths in the same direction, causing an adherant relationship between the two layers of film at transversely extending positions spaced apart relatively to the direction of feed, and then opening out the two layers between two successive adhering regions so that the length of film between the adhering regions forms a tube.
  • the two layers of film are made of thermoplastic material, and the adherance is produced by heat sealing.
  • thermoplastic material which are used for wrapping purposes, particularly those used in the wrapping of goods, such as polyvinylchloride are suitable as these are thermoplastic and suitable for heat sealing, and heat severing. It is also preferred to sever the film on a transverse line of cut at each adherant region so that the tube is detached from the preceding tube and from the film being fed to the tube-forming position. The cut may be made by the application of heat.
  • the film may be supplied in the form of two completely separate flat sheets drawn off separate reels or it may be supplied from a single source in the form of centre-folded double layer film, or any other commercially available double layer film such as J-folded film.
  • the two layers are superimposed one on the other as they are being fed and sealed, so that after the seals are formed, the two layers of film are each stretched lengthwise between the seals and they form a substantially flat envelope which subsequently opens out into the tube. It is much easier to produce adequate seals at speed, when the two layers of film are lying flat one against the other than if they are stretched around a relatively bulky article as in the known method previously described, and this presents one of the advantages of the invention.
  • a tube opening device may be inserted between the two film layers before the layers are caused to adhere to each other, and after the layers have been caused to adhere the device may be activated to open the tube.
  • the tube opening device is a mechanism which is introduced between the film in a collapsed condition in which condition the mechanism is of a minimum thickness, and the method includes the step of operating this mechanism into an erect condition in which it opens out the tube.
  • the tube opening device may be in the form of a nozzle which is inserted between the two layers, and gas is blown out through this nozzle to open the tube.
  • an article to be wrapped is fed into the opened out tube by introducing the article from one end. This may be achieved by causing the tube to move laterally over the article whilst the tube and the article are travelling along side-by-side paths. The article may also be moved laterally but in the opposite direction to the tube.
  • alternate articles are introduced into their respective tubes from opposite sides of the path of the film through the machine.
  • the tube may be sealed at one end between the two transverse seals and this end seal may be formed before or after the opening out action, and the tube may also be sealed across that end through which the article enters after the article has arrived in place to completely envelope the article particularly if the film is to be heat shrunk on to the article.
  • apparatus for carrying out the method of forming a package comprises support means for a supply of two layers of plastics film, means for traversing the two layers of film, one superimposed upon the other, a sealing arrangement for sealing the two layers of film together on transverse lines at positions spaced in the direction of travel of the film, and opening means for opening out the flat envelope of film formed between two adjacent seals.
  • the apparatus includes a tube opening device, and a mechanism for controlling the tube opening device so that it is inserted between the two layers of film at a position on the input side of the sealing arrangement.
  • the apparatus may also include producing relative transverse displacement between the opened out tube and an article to be wrapped, to introduce the article into the tube.
  • the apparatus may also include a product conveyor means adapted to feed an article to be wrapped in the same sense as the film is fed.

  • the purpose of the machine is to wrap articles of regular prismatic shape, and in this particular instance, the machine is intended to wrap rolls of wallpaper, which present a problem in that they are long relatively narrow articles.
  • the rolls must be completely enveloped in heat shrinkable plastics film such as polyvinylchloride, ready for passing through a shrinking zone in which heat is applied to tighten the film on the'paper roll.
  • the machine is a processing machine having a series of stages at which a sequence of pack-forming steps is carried out.
  • the stages are arranged along a horizontal path through the machine (the path being indicated by the line 10,10 in FIG. 2) but it is to be understood that this is a matter of convenience, and the machine could be arranged with a nonhorizontal path.
  • a film feed arrangement generally designated 12.
  • the film feed will be hereinafter described in detail, but, it will be mentioned that there are vertically spaced mountings for reels l4 and 16 of the heat shrinkable plastics film, one above and one below the horizontal path 10..
  • the machine is adapted to bring the two films together and to produce a series of separate packages therefrom, as will be described, but it is necessary to mention at this stage, that the film travels successively over three conveyors; namely a film feed conveyor 18, a wrapper conveyor 20 and a shrink tunnel conveyor 22.
  • the latter passes through a shrink tunnel 24 at the output end of the machine, this tunnel being a known apparatus in which heat is applied to the envelope of film to shrink that film into tight engagement with the article being wrapped.
  • the product conveyor 36 includes a series of carriers 38, which will be described in some detail hereinafter. It is to be noted however, that the carriers 38 do not travel in a rectilinear path as seen in plan (FIG. 3) but in a path designated 40, 42, 44, 46, 48 and 50. During the part of the carrier cycle indicated by the line 40, a carrier travels with a compound movement in the general longitudinal direction and also rearwardly towards the path of the film.
  • the carrier 38 travels parallel with the film, and then it travels in a compound stepped movement, indicated by the lines 44, 46 and 48 forwardly, away from the path of the film, and then along the path 50 parallel with the general longitudinal direction. From the path 50, the carriers 38 return along the bottom run of the conveyor 36.
  • the wrapping function is performed by interaction of the articles carried by the product conveyor 36 and the film as it travels along the conveyors 18, 20 and 22.
  • a housing 54 for the main driving mechanism (not shown) of the machine this driving mechanism including an electric motor and suitable gearing.
  • a control panel 55 is also provided, this being connected to the housing 54 by a trunk 57.
  • the film feed 12 is a known type and therefore need not be described in great detail. It is designed to store the two reels of film 14 and 16 alongside the machine (see particularly FIG. 1) so as to keep the overall length of the machine as short as possible. The axes of the reels are therefore parallel with the general direction of travel through the machine.
  • the reels are supported on a stationary frame 52 which may form part of the general fixed structure of the machine, (as illustrated in FIG. 1) or it may be a free-standing unit which is simply placed in close juxtaposition with the housing 54 for the main driving mechanism.
  • An arm 56 extends forwardly from the housing 54, and at its extremity, it provides a support for one end of a cylindrical rod 58, the other end of which is supported in a lug 60 on the frame 52.
  • the rod 58 is inclined at 45 to the axes of the film reels and to the general path of the film through the machine as seen in plan view. This rod provides a means for changing the direction of travel of the film through an angle of 90.
  • the rod 58 is in a position to receive the film from the upper reel 14, and there is a similar rod 62 for the film from the lower reel 16, the rod 62 being supported at one end in a lug 64 and at its other end by an arm (not visible in FIG. 1) which is similar to the arm 56.
  • Two sets of film tensioning rollers are provided in the film feed assembly 12, one set for each film reel.
  • the upper set comprises three parallel rollers 66, 68 and 70 each extending across the path of the film from the reel 14 to the rod 58, these rollers being journalled so that they are able to rotate about their respective longitudinal axes.
  • the top set also includes two rollers 72 and 74 mounted parallel with the rollers 66, 68 and 70 and interdigitated therewith. Each roller 72 and 74 is free to rotate about its own longitudinal axes, and in addition, its axle is free to rise and fall in corresponding vertical slots 76 (two of which can be seen in FIG. 1) formed in the frame 52 and in the housing 54.
  • the film 80 from the top reel 14 passes in a sinuous path over the roller 66, under roller 72 and over roller 68, under roller 74 and over roller 70 to the rod 58.
  • the film 80 is then passed in a direction indicated by the line 30 in FIG. 3 longitudinally of the machine.
  • the weight of the rollers 72 and 74 is carried by the film 80, and consequently these rollers tension the film. Also the sinuous extension of the film provides a film reservoir which has already been pulled off the reel 14. If the machine requires film more rapidly than it can conveniently be withdrawn from the reel, then the extra film is drawn from the reservoir, the rollers 72 and 74 rising to shorten the path through the reservoir. Conversely, if the film requirement of the machine is less than the rate of feed from the reel, then the rollers 72 and 74 are lowered and the length of the film reservoir is increased.
  • the lower set of tensioning rollers comprises three stationary rollers 82, 84 and 86 and two vertically movable rollers 88 and 90, in an arrangement which duplicates that of the upper tensioning rollers.
  • the film 92 from the lower reel 16 passes through the reservoir provided by the rollers, 82, 88, 84, and 86 and then under an extra guide roller 93 before turning under the turning rod 62 in similar fashion to the upper film 80.
  • the film feed is completed by upper and lower pairs of nip rollers 94 and 96 which are vertically spaced from each other, the rollers of each pair being spring loaded towards each other, and a pair of guide rollers 98 and 100 which are spaced apart a short distance.
  • the film 80 passes through the nip rollers 94 and then under the guide roller 98.
  • the film 92 on the other hand, after leaving its turning rod 62 passes through the nip rollers 96 and over the guide roller 100.
  • the two films 80 and 92 form a mouth, but beyond these rollers the film layers are brought together in a face-to-face relationship by a mechanism to be described, so that they are ready to be formed into an envelope.
  • the film feed provides a means of supplying the film from the two reels 14 and 16 to the rollers 98 and 100. It is, of course, necessary to ensure that the two films are correctly aligned with each other transversely of the machine, and generally the films will be of equal width (as illustrated) so that their longitudinal edges have to be brought into overlying relationship. For this purpose an axial adjustment of the reels 14 and 16 is provided, so that one reel can be moved in an axial direction relatively to the other reel. This is a known method of aligning the two film feeds.
  • top roller 98 does not extend as far forwardly as the bottom roller 100.
