Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a double-sided machine in a corrugating machine that manufactures double-sided corrugated board by laminating and integrating back liner paper on the corrugated surface of a single-sided corrugated pole. be.

Structure of the conventional example and its problems FIGS. 1 and 2 show the conventional example. That is (1)
is a single-sided corrugated board μ which is a laminate of liner paper (2) and paperboard (3), and is transported with the paperboard (3) at the bottom. (4) is a gluing part for adhering adhesive glue (6) to the corrugated surface of the paperboard 13), and a tank 1 containing adhesive glue +5).
6), a gluing roll /l/ (71) that contacts the corrugated surface, a transverse roll /l'181 that contacts this gluing roll (7), and a presser roll lL/( that contacts the liner paper (2)). No. 91 is a backing part for pasting the backliner paper (1) on the corrugated surface of the single-sided corrugated pole (1), and a guide roller for guiding the backliner paper (ID) to apply to the paperboard (3). A/113 and the lower back liner paper I are in sliding contact with the heating medium (13 and the upper liner paper 121 K are in contact with the conveyor belt (campus belt) a4 -
, a presser roll that comes into contact with the upper surface of the working part of this belt conveyor I, and a gooling part US.

According to such a conventional configuration, the paperboard L in the gluing portion i41

is attached, and after applying backliner paper to the corrugated surface to form 17 double-sided corrugated boards, the conveying force of the belt conveyor 04 moves the heating medium (J Dokura Kei), and the heating at that time causes the adhesive to be bonded. Dry the glue (5) and make paperboard (3)
and back liner paper (2) are bonded together and cooled in a cooling section ae.

According to this conventional example, the following problems occur.

In other words, since the back liner paper I forming the double-sided corrugated board /l/(l) slides on the heating medium, scratches occur on the surface of the back liner paper L, especially when the surface is the printed surface. When this occurs, some of the printing may be scratched or erased.Since this problem also exists with regular cardboard, vinyl corrugated poles with a resin coating on the surface are coated with scratch-preventing material. The desired processing cannot be performed unless a supporting paper or other material is attached.

OBJECTS OF THE INVENTION An object of the present invention is to provide a double-sided machine for a corrugating machine that can perform the desired heat lamination without causing surface sliding contact.

Structure of the Invention In order to achieve the above object, the duplexer in the corrugating machine of the present invention has a packer section for pasting back liner paper on the corrugated surface of a single-sided corrugated board μ, and a pair of upper and lower boards, at least one of which has a heating element. It is made up of multiple transfer units.

According to this structure, since the double-sided corrugated cardboard is conveyed while being sandwiched between the upper and lower conveyor belts, surface sliding contact does not occur, and the desired heating lamination is carried out by the heat from the belt conveyor equipped with a heating element. It will be possible to do it.

Embodiment and Function An embodiment of the present invention will be explained below based on FIG. 3 and FIG. fJ4. Note that the same reference numerals as in the conventional example (FIGS. 1 and 2) indicate the same or almost the same components. In this embodiment, a belt conveyor (toward) is provided in place of the conventional heating medium, and a heating element (to) is placed in the belt conveyor (to).
9 are buried. The belt conveyor is, for example, a rubber belt, and the heating element is a heater or a carbon-like resistor. The heating element (19) is connected to a current collector ω exposed on the non-active surface side, and power is supplied through this current collector.

(To) Sexual love indicates loaf. @ indicates Zene board, (2) indicates Uke board, but these are presser low/&/old and Uke is low A/
C21i) may be replaced.

According to the above embodiment, the double-sided corrugated pole Lv surface formed by applying the back liner paper un to the corrugated surface of the single-sided corrugated pole 1) is held between both PEP conveyors 1141Q81, and the double-sided PEP conveyor I14). It is transported by the movement force of rM@. At this time, since the lower belt conveyor [I81] is heated to a high temperature due to the heating element till K, the heat is transferred to the double-sided corrugated cardboard during transfer, thereby drying the adhesive glue (5). The paperboard Lll and the backliner paper un are laminated and integrated.

Figure 5 shows another embodiment in which the upper belt conveyor [41] is also provided with a heating element and a collector.

Effects of the Invention According to the present invention having the above configuration, since the double-sided stage port (Vt) is transferred by being sandwiched between a pair of upper and lower belt conveyors,
It is possible to produce high-quality double-sided corrugated cardboard without any sliding contact and no scratches, and the desired thermal lamination can be carried out reliably without heat from the conveyor belt having a heating element. For these reasons, double-sided cardboard with a printed surface,
Even if it is a vinyl corrugated board whose surface is coated with resin, it can be processed and manufactured without any problems and without using paper or the like.
