At this time, the jig 15 on each side has three pins 16a-16c and is symmetrically installed at both sides, so that six The bone is formed.

On the other hand, when the bone is formed, the pin 16a located at the center of the pins 16a to 16c provided on the jig 15 first contacts the thermal insulation / heat insulating paper 102, and then holds the reference. By keeping the pins 16a and 16c in contact with the insulating / insulating paper 102, even if the bone is deep, deformation or bursting of the insulating / insulating paper 102 is prevented.

As such, for example, the heat insulating / heat insulating paper 102 in which six bones are formed primarily on the heat insulating / heat insulating paper 102 is inserted into the mandrel 13 to be attached thereto. In this state, the bone molding rotating plate 12 is The other jig is rotated at a predetermined angle, and the other jig 15 is formed at this time. After one cycle, the bone is formed over the entire surface of the insulating / insulating paper 102, and the molding of the bone is surely performed by repeatedly pressing the process of forming such a bone.

A pasting member 22 is provided to paste the inside of the insulating / insulating paper 102 so that it can be attached before being joined.

When the cup to supply table 20 is intermittently rotated and the cup to 101 which has been moved through the cup to supply passage 23 from the cup to processing apparatus (not shown) is inserted into the mandrel 21, the 90 The rotating plate is rotated at an angle and pasted to the outer surface of the cup to 101 by the pasting member 22, and the pasted cup to 101 is rotated at 90 ° again to rotate horizontally at the bottom thereof. (11) of the heat insulating / insulating paper fitting hole (11a), that is, the heat insulating cup (101) and the heat insulating / heat insulating paper (102), in which bone is molded and inserted into the bone forming rotary plate (12), are integrally attached. It will be.

In the drawing, reference numeral 25 denotes a pressing member which is pressed upward and downward so that 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 ( 100 is a vacuum inhaler which serves to send the cup recovery path 27 through the cup recovery path by vacuum.

Looking at the operation of the present invention configured as described above in detail as follows.

When the apparatus of the present invention is operated, each apparatus such as each rotating plate 3, 11, 12, the rotating table 7, and the cup to feed table 20 is placed in a predetermined direction (arrow direction in FIG. 1). 1 step at a predetermined angle by the intermittent rotation, and in such a state, the raw paper in the roll state is cut by the heat insulating / insulating paper cutting part 2, and the heat insulating / heat insulating paper 102 thus cut is one end thereof. Clamped by the clamp 4 provided at the edge of the rotating plate 3, and reaches the paste member 5 side by the rotation of the rotating plate 3, the paste is pasted to the side end portion, and the heat-insulating paper 102 is paste-finished. When the bonding member 6 reaches the bonding member 6 side, the bonding member 6 surrounds the insulating / insulating paper 102 while the two semicircles close to each other to form the insulating / insulating paper 102 in a cylindrical shape.

At this time, since the insulating paper 102 is wrapped around the mandrel 8 of the swivel table 7, it maintains a cylinder of a suitable size, and the diameter is formed somewhat larger in consideration of the deviation of the bone.

When the heat insulating / insulating paper 102 thus moved is 3 steps in the state of being inserted into the mandrel 8, the heat insulating / insulating paper which is drilled on the rotating plate 11 by being pulled out of the mandrel 8 by the suction force of a separate vacuum suction mechanism. The insulating / insulating paper 102, which is fitted in the fitting hole 11a and is thus moved, is moved upward by a pressing member made of a bar-shaped plate installed at a lower side when moved by one step. At the same time, the heat insulating / insulating paper 102 is fixed to the mandrel 13 by a separate clamp, which is fitted to the mandrel 13 formed with the valleys 14 protruding from the bottom thereof. Since the bone forming jig 15 partially heats and pressurizes the heat insulating / heat insulating paper 102, a valley is formed in the heat insulating / heat insulating paper 102, and a portion is formed by the rotation of the bone molding rotating plate 12. Go to the step and use other bone forming jig for other goal After the forming step to a predetermined to be formed on the bone parts which have ji is the primary goal over the surface insulating insulating fingers and being formed to press the action is completed by again repeated.

As such, when the shaping of the bone is completed by the jig 15, the clamping force for fixing the thermal insulation / insulation paper 102 is released, and the thermal insulation / heat insulation paper 102 is insulated from the rotary plate 11 located below. When two steps are moved by the rotation of the rotary plate 11 by falling into the heat insertion hole 11a, the cup to 101 having been pasted from the cup to feed table 20 provided thereon is transferred to the inside of the thermal insulation / insulation paper 102. The supply is to be a double paper cup (100).

On the other hand, when the cups 101 are inserted into the heat insulating / insulating paper 102, the cups 101 are not fully inserted. Then, the cups 101 are pressed by pressing the pressing members 25 provided symmetrically in the upper and lower portions. The double paper cup 100 is completed by being integrally inserted into the thermal insulation / heat insulating paper 102 and bonded together. In the next step, the double paper cup 100 is opened while the pressing member 25a installed only at the bottom thereof is upward. Pushed upwards and at the same time being sucked from the vacuum inhaler 26, the finished double paper cup 100 is transported to the cup recovery portion through the cup recovery passage 27, the present invention is such an operation The double paper cup 100 for thermal insulation and heat insulation is manufactured, performing continuously and repeatedly.

On the other hand, in the present invention, as mentioned above, since the irregularly shaped bones formed on the thermal insulation / insulation paper are partially press-molded without pressing by pressing them at once, there is no burst even when the depth of the bones is increased. It is possible to improve the strength of the cup itself by minimizing the temperature, increasing the insulation and heat insulation, and maintaining the strength of the original paper.
