Definitions

  • the present invention relates to a machine or equipment for removing a thin wrapper from meat products.
  • a protective wrapper therefrom, such as a plastics bag or thin sheet or the like.
  • removal of a wrapper takes place manually by a worker assigned to this task who cuts the wrapper and tears it away from the product, often with a lot of fatigue.
  • the wrapper adheres to the meat tenaciously, in the first case due to freezing of the liquids, and in the second case due to the production of jellies or fats on cooking.
  • the pulling effort is therefore very strong.
  • the wrapping film is rather slippery, still due to the presence either of ice or of fats and jellies.
  • the removal operation is therefore long and tiresome and involves a waste of time affecting the production line.
  • tearings of the wrapper may also occur and, as a result, portions of the wrapper itself may accidentally remain attached to the product.
  • an automatic machine for removal of a thin wrapper from a meat product which comprises the combination of a cutting station for carrying out a cut circumferentially of the product in order to sever the wrapper, and a removing station for taking the cut wrapper off.
  • a machine for removal of wrappers from meat products has been shown in Fig. 1 and identified by reference numeral 10. It comprises an infeed line formed for example of a roller conveyor followed by a spacer belt 12 and along which packed products 14 to be opened are moved forward.
  • centering guides 13 for the product are disposed upstream of the infeed line.
  • the infeed line sequentially directs the products 14 to a wrapper-cutting station 15 formed of a carrier surface 16, of the roller type for example, on which cutting means 18 are disposed, which consists for example of rotary blades disposed in a horizontal plane.
  • the rotary blades and carrier surface are movable with respect to each other so that they circumferentially cut the wrapper enclosing the product.
  • the carrier surface 16 can be rotated to advantage according to a vertical centre axis by a drive system 17. In this manner, the product coming onto the surface 16 is rotated according to said vertical axis so that the blades (four in number for example and disposed at the vertices of a square) cut the wrapper along its periphery following a median line.
  • the carrier surface 16 discharges the product with its wrapper severed onto a roller conveyor 20 feeding the product to a heating chamber 21.
  • the heating chamber 21 holds inside it heating means for example comprising steam ejecting nozzles 23 directed to a belt conveyor 22 passing through the chamber in order to carry the product from an inlet end of said chamber to an outlet end of same.
  • the belt conveyor 22 discharges the heated product into a wrapper-removing station 24 comprising pairs of friction rollers 25, 26 acting on the two wrapper portions 32, 33 obtained in the cutting station 15 so as to push them towards respective suction mouths 29, 30 disposed between the rollers of each pair transversally of the movement line of the products.
  • the suction mouths 29, 30 are connected to respective vacuum ducts 27, 28 sending the removed wrappers to disposal.
  • An outfeed line 31 is present at the outlet of the wrapper-removing station 24 for evacuating the products 14' free of their wrappers from the machine.
  • the product 14 formed of a meat mass covered with a thin wrapper such as a thin heat-sealed plastic sheet or the like, comes from the infeed line 11, 12 and is centered on the spacer belt 12 by the centering guides 13.
  • the belt 12 moves the product towards the cutting station discharging it onto the carrier surface 16.
  • the carrier surface 16 starts moving for bringing the product between the blades 19 so that said blades will be disposed alongside the product and in contact therewith.
  • the carrier surface 16 is then rotated by the drive system 17 and the blades carry out a continuous circumferential cut along the wrapper which is therefore divided into an upper half and a lower half.
  • the carrier surface 16 discharges the product onto the roller conveyor 20 which in turn discharges it onto the belt conveyor 22 of the heating chamber. Then the product passes through the heating chamber and this passage enables the wrapper resistance to removal to be reduced, since steam for example present in said chamber will causes jellies and fat (in the case of cooked items) or the ice layer (in the case of frozen items) to melt, thereby eliminating those substances that would keep the wrapper in adhesion relationship with the meat.
  • the lower rollers are such operated that they both rotate in the same clockwise direction thereby discharging the product free of its wrapper onto the outfeed line 31.
  • the blades may comprise means for positioning them against the side walls of the product at a centered location.
  • This means which may be in the form for example of a spring or a power-driven means, is not shown as it can be easily envisaged by a person having ordinary skill in the art.
  • the cutting blades may be of a variable number.
  • the upper peeling rollers 26 may also be dispensed with, should the sucking action of the upper mouth 30 be considered sufficient for the purpose.
