A terminal servomotor 20 is provided at the tip of the main horizontal arm 18 so as to be rotatable about a horizontal rotation axis orthogonal to the direction of the main horizontal arm 18, and is mounted on a support tube 21 connected to the output shaft of the terminal servomotor 20. An intake / exhaust box 6 'is provided, and a hollow male mold 6 is hermetically provided in an opening on the lower surface of the intake / exhaust box 6'. The male form 6 is provided with a plurality of small intake / exhaust holes 6 ".
[0010]
An air hose 9 is connected to a support pipe 21 communicating with an upper portion of the intake / exhaust box 6 ′, and this is connected to a horizontal pipe 22 provided along the main horizontal arm 18, and further, an upright pipe standing outside the main body 7. 23 and the horizontal pipe 22 are connected by the air hose 9, and the horizontal pipe 22 is connected to the compressor 24 and the vacuum pump 25 via the switching valve 8.
[0011]
A horizontal intermittent rotary shaft 26 is provided on the liquid surface of the pulp mold papermaking raw material 2 in the raw material tank 1, and upward and downward hollow female molds 3, 3 are provided above and below the rotary shaft 26 via spoke plates 27, 27. A pulp mold is formed on the inner surface of the hollow female mold 3 in a state where one hollow female mold 3 is immersed in the raw material 2, and the pulp mold is rotated 180 degrees up and down about the rotary shaft 26 and The hollow male mold 6 provided at the end of the robot 5 is inserted and fitted into the hollow female mold 3 which is oriented so that the suction by the female mold 3 is stopped and the male mold 6 is brought into the suction state at the same time. The papermaking pulp mold 10 of No. 3 is delivered to the male mold 6 by suction.
[0012]
As shown in FIG. 5, the hollow female mold 3 is provided with a suction pipe 28 and a blowing pipe 29, and a timing switching valve 30 for suction and blowing is provided on the outer periphery of the horizontal intermittent rotary shaft 26. Then, suction, suction stop, and blowing are performed, and suction and blowing are performed by a compressor 24 'and a vacuum pump 25' (not shown) provided outside the apparatus.
[0013]
Further, the hollow female mold 3 paper-adsorbs the pulp in the mold raw material 2 while keeping the upward direction, and in this state, a vertical cam guide is used to move the pulp to a certain level above the mold raw material 2 by means of a rotary cam or a cylinder. It can be moved up and down linearly (not shown).
[0014]
The papermaking pulp mold 10 transferred to the downward hollow male mold 6 is raised to the position indicated by the solid line in FIG. 3 by the operation of the robot 5, and the hollow male mold 6 is horizontally moved around the vertical center line as shown in FIG. The main body 7 is centered on an intermittent horizontal moving carrier 11 (intermittent horizontal wire mesh conveyor, belt conveyor, pallet conveyor, etc.) provided near the raw material tank 1 as shown in FIG. Then, the main horizontal arm 18 is rotated, and in this state, the hollow male mold 6 is further rotated by 90 degrees, and the hollow male mold 6 is temporarily stopped at a level of about 300 mm above the carrier 11. After checking the condition, it stops about 2.5 mm above the carrier 11, at which level the switching valve 8 is switched to the blowing side, the papermaking pulp mold 10 separates from the hollow male mold 6, is unloaded onto the carrier 11, and is unloaded. Action Repeats (Fig. 6). As described above (FIGS. 7, 8 and 9), the hollow male mold 6 is rotated by 90 degrees when two robots 5 and 5 are used on both sides of the raw material tank 1 when the hollow male molds 6 and 6 are used. This is to avoid interference.
[0015]
The above operations are sequentially performed based on a program set in the program control device 12 in a sequence.
[0016]
The reference numeral 11 'in FIG. 2 denotes an intermittent rotation chain of the carrier, and the reference numeral 31 in FIG. 1 denotes a balancer.

【The invention's effect】
The present invention arranges a vertical articulated robot on one side or both sides of the pulp tank as described above, provides a hollow male mold at the tip, and fits a hollow female mold made of pulp into the male and female. In addition to being able to transfer from a female mold to a male mold by simultaneous blowing suction, the mold can be formed by raising and lowering the hollow male mold along the common center line with the hollow female mold by the action of the above robot, and adjusting the vertical distance to be high. Since the depth of the product can be deeply machined, there is an effect that a high cushion cover or a deep packaging container covering the entire large product such as a toilet bowl can be manufactured.
