The present invention relates to a method for manufacturing a double paper cup for thermal insulation and insulation which has a thermal insulation and insulation paper formed with ribs in a concave-convex shape on the outside of a cup or a cup shape, and has heat insulation and insulation effect.

More specifically, it is intended to bring economical efficiency by minimizing defective products by minimizing defects of the paper by minimizing the defects of the paper by allowing the bones of the heat-insulating paper to be covered with the cup to be formed without bursting (torn). It is intended to provide a manufacturing method and apparatus suitable for this.

In general, the paper cup 100 for thermal insulation has a double structure.

That is, as shown in FIG. 5, the cup-101 forming a general cup shape is inside, and the heat-insulating paper 102 processed to be bent in a concave-convex shape for thermal insulation and insulation to the outside of the cup-101. ) Is used for instant cup noodles or hot beverage containers.

On the other hand, in manufacturing the paper cup 100 of the above-mentioned thin and double cups, the cup to 101 is produced in one device and supplied to the other device side, and in addition, the heat-insulating paper corresponding to the cup outer paper in the other device 102 is cut and bent and then covered and attached to the outside of the cups 101 by the glue pool.

The heat-insulating paper 102 is developed before being covered with the cup to 101, and is inserted into a mold formed of upper and lower boots to bend by heat and pressure. 102 is a state that is developed prior to being covered on the cup to 101 is inserted into the molding frame consisting of the upper and lower frames, the bone is formed to be bent by heat and pressure, wherein the insulating paper 102 is the entire surface As it is pressed by the pressure of upper and lower frames uniformly, the paper itself is stretched and the bone is formed as the bone is formed, and the thickness of the paper itself is different, so it is difficult to maintain even strength when using it. There was a lot of squeeze out of paper caused the paper to burst.

In particular, the thermal insulation paper 102 is required to increase the height of the bone in order to increase the thermal insulation and thermal insulation according to the intended use, but the paper itself is not elastic, so the bone height as the conventional method and apparatus as described above If it is enlarged, there is no elasticity, so part of it is broken (torn).

In view of the above problems, the present invention provides a manufacturing method and apparatus for manufacturing a heat-insulating and insulating joy cup which can be formed without breaking the bone height of the uneven portion of the heat-insulating paper to a height suitable for a use, thereby improving usability and productivity. When explaining the manufacturing method and apparatus according to this to be as follows.

First, look at the manufacturing method for the production of the double cup of the present invention. (See Figure 4)

[Step 1]

After the base paper is cut to the size of the insulating / insulating paper 102, it is pasted to the side edges and rolled into a cylindrical shape around the mandrel 8 to form an adhesive.

At this time, the diameter of the insulating paper 102 is formed with a margin in consideration of the amount of deviation when the bone is formed later.

[Step 2]

The insulating / insulating paper 102 obtained in the first step is transferred to the rotating plate 12 and inserted into the outer side of the mandrel 13 in which the bone is dug, and then the insulating / insulating paper 102 is held by the bone molding jig 13. Is partially heated and pressurized to form a rib in an uneven shape, but in such a state, the thermal insulation / insulation paper 102 is formed to be formed over the entire surface while correspondingly contacting the other bone forming jig 15.

If the bone is partially formed in this manner, it is possible to prevent the thermal insulation / insulation paper 102 from bursting and at the same time increase the height of the bone.

[Step 3]

The finished cups 101 are obtained by inserting the cups 101 pasted on the outer surface of the heat-insulating paper 102 in which the valleys are formed.

The thermal insulation and heat insulation cup 102 completed in this way is sent to a cup collection container by a vacuum suction machine (refer to reference numeral 26 in FIG. 1), and is recovered.

Hereinafter, a device suitable for the manufacturing method of the double paper cup as described above will be described.

This apparatus supplies the heat insulating / heat insulating paper processing apparatus 1 and the heat insulating / heat insulating paper 102, which are divided into large portions as shown in the plan view of FIG. The cup to 101 which is formed to be bent into an uneven shape and supplied from a separate cup or processing apparatus (not shown) is inserted into the heat insulating / insulating paper 102 to obtain a finished double paper cup 100. Each is divided into devices 10.

The above-mentioned heat insulating / heat insulating paper processing apparatus 1 clamps the heat insulating / heat insulating paper cutting part 2 and the cut heat insulating / heat insulating paper 102 which cut the raw paper to a predetermined size by clamping the predetermined angle. Rotating plate (3) intermittently rotating and the heat-insulating paper 102 is glued to the side plate of the heat-insulating paper (102) when the heat-insulating paper 102 is clamped and rotated (Stencil) (5) And a bonding member 6 for wrapping the pasted insulating and insulating paper 102 in a cylindrical shape, and a mandrel 8 serving as a molding frame therein when the insulating and insulating paper 102 is wound and attached in a cylindrical shape. Each of the rotating tables 7 has a combination structure.

As shown in the plan view of FIG. 1 and the schematic front sectional view of FIG. 2, the cup manufacturing apparatus 10 is insulated from the rotating table 7 of the above-described heat insulation / heat-insulating paper processing apparatus 1 on one side (right side of the drawing). The rotary plate 11 is intermittently rotated at a predetermined angle by receiving the thermal paper 102. The rotary plate 11 is fitted with a plurality of heat insulating / insulating paper at a predetermined angle. The hole 11a is drilled.

In addition, on one side of the rotary plate 11 (which is left in the drawing), a bone-forming rotary plate 12 having a plurality of (8) mandrels 13 is provided, and the outside of each mandrel 13 is provided. A valley 14 is formed on the surface at a predetermined depth, and the bone forming rotary plate 12 also intermittently rotates at a predetermined angle.

Insulating and insulating paper 102 is provided on both side portions of the mandrel 13 corresponding to six of the eight mandrel 8 of the bone-forming rotating plate 12 except two adjacent to the rotating plate 11. Corrugating jig 15 is formed symmetrically by heating and pressurizing to be bent into irregularities.

That is, the bone forming jig 15 has three pins 16a such that the ends thereof are connected in correspondence with the valleys 14 of the mandrel 13 in the frame 15a of a predetermined shape as shown in the planar cross-sectional view of FIG. (16) and (16c) are formed, and these pins (16a)-(16c) are supported by the coil springs (17).

Therefore, when the jigs 15 on both sides are moved to the mandrel 13 by a separate pressurizing device, the ends of the pins 16a to 16c are formed to be bent by pressing the insulating / insulating paper 102. At this time, since the jig | tool 15 of both sides has three pins 16a-16c of each, and is installed symmetrically in both sides, six bone | grains are formed in a thermal insulation and insulation paper.

On the other hand, when the goal is formed, the pin 16b located in the middle of the pins 16a-16c provided on the jig 15 is set to contact the thermal insulation / heat insulating paper 102, and then two pins on both sides are formed. Deviation or bursting of the thermally insulating and insulating paper 102 is prevented even if the bone is deep by making a deviation such that the (16a) and 16c are in contact with the thermally insulating and insulating paper 102.

Thus, for example, when the six valleys 14 of the thermal insulation / insulation paper 102 are formed, the bone molding rotating plate 12 is then rotated at a predetermined angle to be located at the place where the other jig is installed. The bone is formed on the whole surface of the thermal insulation / insulation paper 102 after completion of a predetermined cycle by forming the bone by the above-described action by another jig 15 where the other bone is not formed. By pressing the process of bone formation again and again, the shaping of the bone is surely made.

Reference numeral 20 denotes a cup to feed table installed on the upper part of the rotating plate 11, and the heat insulating / insulating sheet fitting hole 11a in which the cup to 101 is drilled on the rotating plate 11 by the cup to supply table 20. ) Is supplied to the inner side of the thermal insulation / insulation paper 102 sandwiched between the layers.

The cup to feed table 20 has the same shape as the rotary table 7 provided in the above-described heat insulating / insulating paper processing apparatus 1, and is installed vertically.

Four mandrels 21 into which the cups 101 are fitted are formed at the circumference, and the cups 101 are inserted into the heat insulating / insulation fitting holes 11a on one side of the cup to supply table 20. A pasting member 22 is provided to paste inside the heat insulating / insulating paper 102 so that it can be attached before being joined.

The cup to feed table 20 is rotated intermittently and the cup to 101, which has been moved through the cup to feed passage 23 from the cup to processing apparatus (not shown), is inserted into the mandrel 21. The paste is applied to the outer surface of the cup to 101 by the paste member 22 by rotating it at an angle, and the paste is performed as described above. Insulating / insulating paper 102, which is inserted into the insulating / insulating paper fitting hole 11a of the rotating rotating plate 11, that is, the bone is molded and inserted in the bone molding retardation block 12, is supplied to the inner side to be cupped. The 101 and the thermal insulation paper 102 are integrally attached.

In the drawing, reference numeral 25 denotes a pressing member pressed in the up and down direction so that the adhesion thereof is firm after the cups 101 are supplied into the insulating / insulating paper 102, and reference numeral 26 denotes a completed insulating / insulating cup (1000). It is a vacuum inhaler which serves to send the cup recovery passage 27 through the cup recovery passage 27 by the air suction.

Looking at the action and effect on the device of the present invention configured as described above in detail.

When the device of the present invention is designed, each device such as each rotating plate 3, 11, 12, the swivel table 7, and the cup to feed table 20 is set in a predetermined direction (arrow direction in FIG. 1). In this state, the raw paper in the rolled state is cut by the thermal insulation / insulation paper cutting part 2, and one end portion is clamped by the clamp 4 provided at the edge of the rotating plate 3. When the rotating plate 3 reaches the pasting member 5 side by rotation, it is pasted to the side end portion. When the pasting is completed, the insulating / insulating paper 102 reaches the joining member 6 side. ) Wraps the insulating / insulating paper 102 while the two semicircular bodies are closed to each other to form the insulating / insulating paper 102 in a cylindrical shape.

At this time, the thermal insulation paper 102 is wrapped around the mandrel (8) of the swivel (7) by heavy force to maintain a cylinder of the appropriate size and the diameter is formed somewhat larger in view of the deviation that the bone is formed later.

The heat insulating / insulating paper 102 thus moved is moved from the mandrel 8 by a separate suction hole and moved to the heat insulating / heat insulating paper 11a which is drilled by the rotating plate 11 by moving the three steps while being inserted into the mandrel 8. When the insulation and the insulating paper 10 inserted in this way are moved up by one step, they are raised upward by a pressing member made of a rod formed under a separate bottom, and protrude to the bottom of the bone-forming rotating plate 12. 14) is inserted into the mandrel (1) is formed to move thereafter, since the bone forming jig 15 is partially heated and pressurized, the heat-insulating paper (102) is formed in the bone in part of the bone forming rotary plate ( 12) By moving to the next step by rotation, the bone is formed on the part where other bone is not formed by other bone forming jig. After the predetermined step, the primary bone is formed over the whole surface of the thermal insulation / insulation paper. Press it again and again It is completed the action.

When the bone is formed by the jig 15 in this manner, the heat insulating / insulating paper 102 falls back to the heat insulating / heat insulating paper fitting hole 11a of the rotating plate 11 located in the lower portion, and is rotated by two steps by the rotation of the rotating plate 11. When it moves, the composite 101 which is completed to paste from the cup to feeder 20 installed thereon is supplied to become a double cup 100.

On the other hand, when the cup 101 is inserted into the heat insulating / insulating paper 102, the cup is not fully inserted. Therefore, the cup 101 is pressed by pressing the pressing member 25 symmetrically installed at the upper and lower portions thereof. The double cup 100 is completed by being integrally inserted into the heat insulating / insulating paper 102 and bonded to each other. In the next step, the pressing member 25a installed only at the lower side is pushed upward, and the double cup 100 is pushed upward. At the same time, since the suction from the vacuum inhaler 26 is completed, the finished double cup 100 is transported and dropped to the cup recovery portion through the cup recovery passage 27. The present invention continuously keeps performing such an operation repeatedly. The double cup 100 for insulation is manufactured.

On the other hand, the present invention, as mentioned above, because the partially formed by pressing without pressing the uneven-shaped bone formed in the thermal insulation / insulation paper at once and shaping, there is no burst even when the depth of the bone increases In addition to minimizing the occurrence of heat and heat insulation, it is possible to maintain the strength of the original paper, thereby improving the strength of the cup itself.
