ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a combination of a sheet roll comprised of a heat transfer recording sheet used in thermal facsimile devices with a subshaft, a packaging apparatus thereof, and a production system thereof.
2. Related Background Art
Conventional facsimile devices use a heat transfer recording sheet rolled on a roll shaft in the form of roll. This recording sheet is also called as a donor, which has such a structure that a hot melt ink layer consisting of a binder of wax, resins, etc., and a color agent is laid on one surface of a thin, plastic film base, for example, of polyester. The ink layer of recording sheet is overlaid on paper, and the back face of recording sheet is heated by a heating means such as a thermal head to transfer ink to the paper, thereby effecting printing. Such facsimile devices are provided with an apparatus for indicating the end of recording sheet.
For indication of the end of recording sheet, an end mark with a reflective surface is normally provided in the vicinity of a shaft fixed end (terminal end) of recording sheet to a roll shaft. This end mark is given on either the hot melt ink layer side or the opposite side thereto of the recording sheet, and is optically detected by a sensor having a light source and a photodetector. This end mark is printed on the recording sheet by flexography or gravure printing.
As described above, the heat transfer recording sheet is wound in a roll form around a roll shaft, which is used in facsimile devices. Incidentally, the recording sheet wound around a roll shaft forms a sheet roll, which needs a subshaft for rolling the used recording sheet fed out from the roll shaft when used in facsimile devices. In this case, the leading end of the recording sheet is rolled on the subshaft, so that the sheet roll is combined with the subshaft to compose a combination. Every combination is transported or stored.
Meanwhile, such a combination of a sheet roll with a subshaft is set in a container and thereafter is packaged, but presently there is no method for quickly and surely packaging the combination.
SUMMARY OF THE INVENTION
The present invention has been accomplished taking account of the above points, and an object of the invention is to provide a combination of a sheet roll with a subshaft, a producing apparatus of the combination, a packaging apparatus of the combination, and a production system of the combination.
A first feature of the present invention is a combination system for producing a combination of a sheet roll with a subshaft, comprising: a combination producing apparatus for winding up a lead sheet to wrap a sheet roll obtained by winding a heat transfer recording sheet around an outer periphery of a roll shaft, and a subshaft with a smaller diameter than that of the sheet roll, thereby producing the combination of a sheet roll with a subshaft; and a combination packaging apparatus for packaging the combination of a sheet roll with a subshaft, with a package bag and transferring packaged combinations into a container as alternately reversing orientations thereof to encase the combinations in the container.
A second feature of the present invention is a combination producing apparatus for producing a combination of a sheet roll with a subshaft, comprising: an uncrumpling and cutting apparatus for cutting an end portion of a heat transfer recording sheet of a sheet roll obtained by winding the heat transfer recording sheet around an outer periphery of a roll shaft, by a predetermined length; a lead sheet sticking apparatus provided on a downstream side of said uncrumpling and cutting apparatus, for making one side edge of a lead sheet of a predetermined length overlap with the cut end portion of the heat transfer recording sheet thus cut and sticking said one side edge to the end portion by sticking means; a subshaft sticking apparatus provided on a downstream side of said lead sheet sticking apparatus, for sticking a subshaft to another side edge of the lead sheet stuck to said sheet roll; and a lead sheet winding apparatus provided on a downstream side of said subshaft sticking apparatus, for winding up said lead sheet so as to wrap said sheet roll and said subshaft with said lead sheet.
A third feature of the present invention is a combination packaging apparatus for packaging a combination of a sheet roll with a subshaft, comprising: a tying portion for tying with a strip a combination of a sheet roll with a subshaft, formed by winding up a lead sheet to wrap therewith the sheet roll obtained by winding a heat transfer recording sheet around an outer periphery of a roll shaft, and the subshaft with a smaller diameter than that of the sheet roll; a packaging portion provided on a downstream side of the tying portion, for packaging said combination thus tied with a package bag; a transferring and mounting portion provided on a downstream side of the packaging portion, for laying combinations packaged in package bags as alternately reversing orientations thereof; and an encasing portion provided on a downstream side of the transferring and mounting portion, for encasing the combinations laid by the transferring and mounting portion, in a container.
According to the first feature, the combination producing system can form a combination by rolling to wrap a sheet roll and a subshaft with a smaller diameter than that of the sheet roll with a lead film, and can easily and continuously pack such combinations in containers.
According to the second feature, when a sheet roll is put into the uncrumpling and cutting apparatus, the uncrumpling and cutting apparatus cuts the end portion of heat transfer recording sheet in the sheet roll by a predetermined length and uncrumples the recording sheet. Then the sheet roll is carried to the lead sheet sticking apparatus, and the lead sheet sticking apparatus sticks one side edge of a lead sheet of a predetermined length to the end portion of heat transfer recording sheet. Next, the sheet roll is carried to the subshaft sticking apparatus, and the subshaft sticking apparatus sticks the other side edge of the lead sheet to the subshaft. The sheet roll with the subshaft stuck to the other edge of the lead sheet is then carried to the lead sheet winding apparatus, and the lead sheet winding apparatus winds up the lead sheet to wrap the sheet roll and the subshaft therewith, thereby obtaining the combination of the sheet roll with the subshaft.
According to the third feature, the tying portion of the combination packaging apparatus ties the combination of the sheet roll with the subshaft in a bundle with a strip, and the packaging portion packages the tied combination in a package bag. Combinations each packaged in package bags are laid as alternately reversing their orientations in order by the transferring and mounting portion, and the combinations laid by the transferring and mounting portion are encased in containers by the encasing portion.
