Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for paper-making large-sized molded products using a valve mold.

``Conventional technology'' In conventional molded product papermaking equipment, when transferring a molded product from a female papermaking die to a male die, the product is blown out from the female die, sucked into the male die, and transferred, and then transferred from the male die onto a conveyor. It was to be blown out and conveyed to a dryer. The female mold and the male mold were each provided on a rotating drum, faced each other at opposing portions of both drums, and the delivery was performed when they matched and fitted. Therefore, the depth of the female and male molds is limited, and is limited to the production of small molded products with a depth of about the same depth as a chicken egg case, such as cushioning materials for toilet bowl packaging with a wall thickness of 5 to 6 cm and a depth of LOm+++. However, there is a problem in that it is difficult to apply it to the paper making of large molded products.Also, for small molded products, the two rotating drums mentioned above could be delivered while being continuously rotated, but in the case of large molded products. In the paper making of deep molded products, the drum becomes large and can rotate continuously, and the delivery must be carried out in a stopped state, and there are problems in that it is difficult to determine the positioning accuracy of the female mold and the male mold.

"Problems to be Solved by the Invention" The present invention provides a large-sized paper making device that automatically mass-produces large molded products with a relatively deep depth, such as upper and lower surface covering packaging for toilet bowls and other large products, and cushion materials. The purpose is to obtain.

"Means for Solving the Problems" In order to achieve the above object, the present invention includes a rotating drum supported by a horizontal axis on a machine frame, a female die for papermaking facing outward on the drum, and In the mold paper making machine, the drum is an intermittent rotating drum, and the machine is configured to have a papermaking raw material tank arranged so that the papermaking mold is transferred from the female die to the male die by blowing from the female die to the male die and transferring the papermaking mold from the female die to the male die. An intermittent reciprocating sliding frame is installed on a horizontal rail provided above, an interlocking mechanism is provided between the sliding frame and the drum, and a male lifting device is installed on the sliding frame, and the drum and sliding frame are connected to each other. A stop positioning device is provided, and a fitting guide device for the lowering male die and the upward female die is provided on the male die and the female die, and a male type floating portion by the guide device is provided on the lifting device. It consists of a large-sized molded product paper-making device.

"Operation" Therefore, the rotary drum 1 is rotated in the direction of the arrow a and stopped, and the raw material 13 for papermaking in the raw material tank 12 is suctioned into the female mold 5 which is facing downward to form paper, and the female mold 5 is rotated until the female mold 5 is facing upward. When it is rotated and stopped by the positioning device 8, the interlocking mechanism 4
As a result, the sliding frame 3 moves forward along the horizontal rail 2.2 and stops, and the male mold 6 is lowered by the lifting device 7. During its descent, the male mold 6 is guided by the fitting guide device 9, and the slight movement of the male mold 6 in the horizontal direction due to the guidance is allowed by the floating part 10 provided in the lifting device 7. The mold 5 and the lower male mold 6 can be matched in relative position. In this state, the paper-making mold 14 sandwiched between the female mold 5 and the male mold 6 is delivered to the male mold 6 side by air blowing from the female mold 5 and suction from the male mold 6. In this state, the male mold 6 rises and separates from the female mold 5, and the rotating drum 1
rotates again in the direction of arrow a, the female die 5 rotates toward the raw material tank 12, and the male die 6 moves back along with the sliding frame 3 to the top of the carry-out conveyor 15, so that the papermaking mold 14 The mold is unloaded onto the conveyor 15 by air blowing from the male mold 6, and the same operation as described above is repeated.

Embodiment An intermittent rotating drum 1 is supported on a machine frame 16 by a hollow horizontal shaft 17, and the drum 1 is rotated by the horizontal shaft 17.
