Definitions

  • the present invention relates generally to improvements in packaging and more particularly to an improved apparatus and method for wrapping an article in a sealable flexible sheet material.
  • the present invention is particularly suitable to the packaging of food products such as cheese or meat which are susceptible to deterioration.
  • suitable flexible sheet materials are employed.
  • the method and apparatus of the present invention is adapted to package articles in a controlled atmosphere or environment.
  • An important object of this invention is to improve the prior practice by providing a method and apparatus which is capable of determining whether conditions of the atmosphere within the tube are satisfactory to insure the formation of packaged units having a proper gas analysis.
  • a controlled atmosphere is caused to flow from an enclosed area immediately adjacent a point where the film is folded to form a tube and which atmosphere is directed upstream over the units contemporaneous with the movement of the units and the tube toward a transverse sealer and cutter.
  • An exhaust pipe is disposed within the film tube and has an inlet positioned immediately adjacent to the closed end of the film tube where the transverse seals are being formed by the transverse-sealer mechanism.
  • This exhaust pipe is connected with an atmosphere analyzer so that atmosphere can flow into the exhaust pipe and be analyzed before any packages are formed. If the operator finds that the analyzer indicates that the condition of the atmosphere within the tube is satisfactory for the commencement of the formation of packages, then the operator starts the machine and units such as cheese are immediately packaged without any loss of wrappers. After production of packages has commenced, the condition of the atmosphere may be checked at any time.
  • Our method constitutes an improvement over prior techniques where it has been necessary for a few packages to be manufactured and taken to a laboratory for gas analysis each day before full speed operation is commenced to determine whether the machine is producing packages having the desired gas analysis. After production has started, it has been the practice in the past to take samples to the laboratory every fifteen minutes or so to provide a further production control. Where the gas or atmosphere has not been satisfactory in the packages manufactured, such packages have been discarded and a loss of material and time results from the aforesaid techniques employed prior to this invention.
  • an important object of this Patented Sept. 27, 1966 invention is to provide a new and improved method and apparatus for manufacturing packaged units having a controlled atmosphere with a minimum loss of film and opcrating time incident to the commencement of the operation of the apparatus.
  • Yet another object of this invention is to provide a new and improved method and appanatus for packaging units where the analysis of the atmosphere of each package is immediately available at the time that the package is being made so that an operator can determine whether packages are being produced having the desired atmosphere or environment without having to take the packages to a laboratory for an independent statistical analysis.
  • Another and more specific object of this invention is to provide (a new and improved method of sweeping cheese units within a fihn tube with a gas or other suitable atmosphere and then removing the gas or atmosphere from the tube without intermixing the gas being removed wth the gas being flushed into the tube so that the gas being removed may be injected into an analyzer to determine whether packages are being produced having desired atmosphere and so that portions of the gas or atmosphere being removed can be directed against undersides of the articles being packaged for scrubbing these undersides to further inhibit deterioration of the article within the package.
  • Still another important object of this invention is to provide 'a method and apparatus for manufacturing a packaged food unit having a longer shelf life and which article is more resistant to deterioration.
  • FIGURE 1 is a diagrammatic view of an apparatus for the packaging of articles in accordance with this invention.
  • FIGURE 2 is an enlarged fragmentary top plan view showing in greater detail certain features of the wrapping apparatus shown in FIGURE 1;

As the conveyor belt 15 moves past the roll 13, the lugs 16 cooperate with the moving film 12 to cause the units 17 to be deposited on top of the film in longitudinally spaced relation along the length of the film strip.
  • a pair of spaced film folding shoes or plates 18 Carried upon the top side of the frame or horizontal bed 11 is a pair of spaced film folding shoes or plates 18 which are provided with opposed converging side edges 18a as well as flat top surfaces 18b.

  • the heated elements 2222 are provided to heat opposite edges 12b12b of the film after film side portions 12a 12a have been folded about opposite sides of the unit 17 being packaged.
  • the rollers 26 are pivotally mounted at 26a on legs 26b which are mounted on a U-shaped frame 26, which frame is carried or attached to the shoes 18 18. It will further be appreciated that after the film has passed through the rollers 2626 a sealed film tube is formed about the longitudinally spaced units 17.
