[0002]

2. Description of the Related Art For example, foamed styrene is mainly used for heat insulation containers used for cup noodles and the like. However, due to problems such as environmental hormones and combustible waste, the heat insulation containers are being replaced with paper heat insulation containers. In order to obtain a heat insulating container made of paper, it is preferable to use embossed paper.

Conventionally, when manufacturing this type of embossed product, for example, equipment shown in FIG. 5 is provided. That is, the embossed base paper 71 and the printing paper 72 are fed from the unwinders 73 and 74, respectively. Embossed base paper 71
First, embossing is performed in an embossing machine 80 to form embossed paper 75, and then the paste is transferred to the convex portion of the embossed paper 75 in a sizing machine 81. Further, the printing paper 72 is preheated by the heater roll 82, and enters the pressure-bonding dryer 83 together with the embossed paper 75 glued as described above, and is interleaved into the embossed sheet 76.

[0004] Here, the pressure dryer 83 is provided with a weight roll 84.
The embossed sheet 76 is sandwiched between the upper and lower two belts 87 and 88 guided by the receiving roll 85 or the hot platen 86, and the embossed sheet 76 is pressed and dried by the holding force and the heat from the hot platen 86.

[0005] The embossed sheet 76 that has been interleaved and exits from the pressure dryer 83 is cut in the width direction by a slitter 89, and then cut by a cutter 90 into individual sheets 77. The individual sheets 77 are separated by a slow conveyor. It is stacked on an integrated device 92 via a device 91 or the like. After that, every sheet 77
Is conveyed to the next step, where it is
After being punched one by one into a developed shape, they are conveyed to a container production line.

[0006]

However, according to the above-mentioned conventional embossed product manufacturing equipment, (a) each device and device 80, 81, 83, 89, 90, 9
2 is a single unit, so the installation space is large.

(B) Because the line is long and individual operation,
The speed is not increased and the production efficiency is reduced. (C) In the sizing machine 81, the embossed paper 75
Therefore, it is difficult to adjust the gap between the glue rolls, and moisture may migrate to the embossed paper 75 after thermoforming, and the embossed paper 75 may be softened.

(D) In the pressure-bonding dryer 83, the embossed paper 75 after gluing is dried while being pressed by the group of rolls 84, which causes deformation of the emboss.
In addition, since the emboss has an air layer, the thermal efficiency is significantly reduced.

(E) The production speed cannot be increased because the adhesive drying ability of the pressure dryer 83 is low. In order to increase the production speed, expensive quick-drying vinyl acetate-based glue must be used.

(F) A flat sheet-shaped sheet of paper 77 with a cutter 90
Therefore, a punching machine for punching into a developed shape in the next step is required. (G) Since the embossed sheet 76 is cut into flat sheets 77, a margin for cutting is required, and the effective use rate of the embossed sheet 76 becomes low. There is such a problem.

Therefore, an object of the present invention is to provide an embossed product manufacturing facility capable of solving the above-mentioned problems.

[0012]

In order to achieve the above-mentioned object, an embossed product manufacturing apparatus of the present invention is provided with an embossed forming section comprising a pair of heated forming rolls and an embossed paper on one of the heated forming rolls. An embossed sheet manufacturing machine is composed of a gluing section that transfers the glue to the other side, and a press-drying section that sandwiches the embossed sheet, in which the face paper is interleaved with the embossed paper after the gluing, between one of the heat forming rolls. A slitter for adjusting the width of the embossed sheet, a punching machine for punching the embossed product from the embossed sheet, and a winding machine for the remaining paper after the punching were arranged in this order on the downstream side of the embossed sheet manufacturing machine. It is characterized by the following.

Therefore, according to the first aspect of the present invention, in the embossed sheet manufacturing machine, the embossed paper can be formed by the pair of heat forming rolls in the emboss forming section, and then the embossed paper on one of the heat forming rolls in the gluing section. The emboss sheet can be manufactured by transferring the glue to an embossed sheet, and sandwiching the embossed sheet in which the surface paper is interleaved with the embossed paper in one of the thermoforming rolls in the pressing and drying section. The manufactured embossed sheet is subsequently trimmed in width by a slitter device, and the embossed product is punched by a punching machine to produce an embossed product, and the remaining paper after punching is continuously taken up by a winder.
