Abstract
A packaging machine has a wrapping device for forming a tubular wrapping from a continuous web of heat-seal material, and for feeding products successively into the tubular wrapping; each product being located between two free tubular portions of the tubular wrapping, which are folded substantially onto the relative products, and are stabilized by at least one pair of sealing devices, each of which has a sealing surface heated electrically by a heating device, operation of which is controlled by a control device carried by the sealing device and for determining an actual temperature of the sealing surface.
Claims (12)
1) A packaging machine for wrapping products in respective sheets of heat-seal wrapping material, the machine comprising wrapping means for forming a tubular wrapping from a continuous web of heat-seal material, and for feeding the products successively into the tubular wrapping, each product being located between two free tubular portions of said tubular wrapping; sealing and feed means comprising at least one pair of sealing devices movable along a sealing path to feed a said product at a variable travelling speed along the sealing path, and to perform a respective sealing operation on a respective said tubular portion, each sealing device having a hot sealing surface; and, for each sealing device, heating means for electrically heating the relative sealing surface; and being characterized in that each sealing device has control means for determining an actual temperature of the relative sealing surface, and for controlling said heating means as a function of said actual temperature.
2) A packaging machine as claimed in Claim 1, wherein said heating means comprise a heating device having sliding electric contacts and in turn comprising at least one fixed guide made of conducting material, and at least one sliding brush, which is also made of conducting material, is carried by the relative sealing device, and engages said guide in sliding manner.
3) A packaging machine as claimed in Claim 2, wherein each sealing device is movable along an endless path comprising said sealing path; the relative said guide being an endless guide.
4) A packaging machine as claimed in Claim 2, wherein said heating means also comprise a voltage regulating device carried by the relative sealing device and connected electrically to said brush; the regulating device selectively controlling the electric current supplied to the relative sealing surface as a function of a comparison between said actual temperature and a desired sealing temperature of the sealing surface.
5) A packaging machine as claimed in Claim 4, wherein each sealing device comprises a carriage movable along said sealing path; and a sealing bar having said sealing surface and fitted to the carriage to oscillate about a relative axis with respect to the carriage; the relative said brush being carried by said carriage, and the relative regulating device being carried by said sealing bar.
6) A packaging machine as claimed in Claim 5, wherein said heating means comprise an electric connector interposed between the relative brush and the relative regulating device and comprising a first element angularly integral with the relative sealing bar and connected electrically to the relative regulating device, and a second element connected in rotary manner to said first element and connected electrically to the relative brush.
7) A packaging machine as claimed in Claim 1, wherein said control means maintain the temperature of said sealing surface substantially constant.
8) A packaging machine as claimed in Claim 1, wherein said control means selectively control the temperature of said sealing surface as a function of the production speed of the packaging machine.
9) A packaging machine as claimed in Claim 1, wherein said control means selectively control the temperature of said sealing surface as a function of the type of said heat-seal material.
10) A packaging machine as claimed in Claim 1, wherein said control means reduce the temperature of said sealing surface in the event of malfunctioning of the packaging machine.
11) A packaging machine as claimed in Claim 1, wherein each sealing device comprises an electric resistor; said control means determining an actual value of said electric resistor.
12) A packaging machine as claimed in Claim 1, and comprising, for each said sealing device, actuating means for moving the sealing device with a law of motion independent of the law of motion of the other sealing device.
