Two adjusting members 32 and 34 are provided at upper and lower positions on the side of the supporting shaft 26 where the rotating member 24 is located. The lower adjusting member 32 has a support rod 36 in a horizontal direction. It is fixed toward the wheel shaft 6 side. The support rod 36 has a function of moving a cutting blade 48, which will be described later, toward and away from the plaster mold 8 by the rotation of the rotation shaft 22.

On the lathe shaft 6 side of the support rod 36, there is provided a blade support piece 40 for supporting the blade support rod 44 in a direction perpendicular to the support rod 36.

An adjustment knob 46 is provided on the blade support piece 40 so that the blade support rod 44 can be moved back and forth along the support rod 36. A handle 50 is provided at the end of the blade support rod 44 on the support member 20 side.

The above-mentioned adjustment knob 46 is for adjusting the sandwiched state when the blade support rod 44 is sandwiched between the blade support pieces 40, and the handle 50 moves the blade support rod 44 back and forth. It is for adjusting the contact angle between the cutting blade 48 and the gypsum mold 8.

A cutting blade 48 is attached to the tip of the blade support rod 44, but it is necessary to adjust the distance between the cutting blade 48 and the peripheral edge of the kneaded material W according to the size and type of the kneaded material W. The blade support rod 44 is designed to be movable in the front-rear direction. The movement is adjusted by operating the handle 50 as described above.

A member 41 is provided at the end of the support rod 36 on the gypsum mold 8 side, and the above-mentioned blade supporting piece 40 is supported by the member 41 in a right angle direction, and the member 41 supports the blade. The holding piece 40 is held, but an adjusting knob 42 is provided to control the holding state.

The cutting blade 48 is supported by the tip of the blade support rod 44. As shown in FIG. 4, the cutting blade 48 is provided with an L-shaped cross section and has a blade tip 49 formed on one side, and a guide portion 51 for discharging the cut excess kneaded clay D on the other side. ing.

The support rod 52 is also fixed to the adjustment member 34 in the horizontal direction. Like the support rod 36, the support rod 52 is configured to follow the turning action of the turning shaft 22.

The support rod 52 follows the turning action of the turning shaft 22 so that the cutting blade 48 and a suction tube 64, which will be described later, approach or move away from the gypsum mold 8.

At the tip of the support rod 52, a suction pipe support piece 54 is provided at a right angle.

A suction pipe support rod 58 is provided on the suction pipe support piece 54, and a suction pipe holding member 68 having an opening 61 inside is provided at the tip of the suction pipe support rod 58.

That is, the opening 62 of the suction tube 64 is mounted in the opening 61 of the suction tube holding member 68 and is brought close to it during use. However, as described above, the cutting blade 48 depends on the size and type of the kneaded clay W. Since the distance to the kneaded clay W is correspondingly adjusted to the perspective, it is necessary to move the opening 62 of the suction pipe 64 so as to follow the cutting blade 48. Therefore, the suction pipe support rod 58 is movably provided. ing. For that purpose, although not shown, knobs corresponding to the adjusting knobs 42, 42 may be provided.

The position of the opening 62 of the suction pipe 64 is behind the cutting blade 48 (on the discharge direction side of the surplus kneaded clay D) and maintains a constant distance from the cutting blade 48.

The reason why the constant spacing is provided between the cutting blade 48 and the cutting blade 48 is that a constant blank space is formed between the cutting blade 48 and the opening 62 so that the flow of the sucked air is increased. This is because the passage is formed in the space, and it is intended that the excess kneaded clay D is stably introduced into the suction pipe 64 by the uniform air circulation.

For the purpose of adjusting the distance between the cutting blade 48 and the opening 62 of the suction tube 64 shown in the drawing, both 48 and 62 are independently configured via the support rods 36 and 52. Although not shown, for example, the support rod 36 may be omitted, and the suction tube holding member 68 may be provided integrally with the cutting blade and the opening of the suction tube by setting a constant distance.

A rod 72 is rotatably provided at one end of the rotating plate 25 via a pin 70, and the other end of the rod 72 is connected to the movable rod 10 side of the swing rod 74.

The swing rod 74 is rotatably attached to a side portion of the base 4 by a support shaft 76. The lower end portion of the swing rod 74 has a structure that follows a cam 78 that is driven and rotated by a drive source provided on the base 4 of the molding machine 2.

The cam 78 is configured to rotate in synchronization with the molding operation of the molding machine 2, and the lower end of the rocking rod 74 rocks along the shape of the cam 78 by the rotation of the cam 78. become.

As a result, the rotational movement of the cam 78 is replaced by the linear movement of the rod 72 via the swing rod 74.

One end of a spring 80 is attached to the other end of the rotating plate 25, and the other end of the spring 80 is attached to an attachment portion 82 provided on the upper surface of the support member 20, so that the linear movement of the rod 72 can be reciprocated. It is biased in a certain direction.

Next, the recovery unit 83 will be described. There is a cylindrical main body 84, an opening 86 is provided on the side surface of the main body 84, and the suction pipe 64 is connected.

Another opening is provided on the upper surface of the main body 84, and the tube 90 is connected to the opening. A filter 92 is attached to the tip of the tube 90 facing the inside of the main body 84, and the other end of the tube 90 is connected to a suction source such as a vacuum pump or a blower (not shown). .

A cylinder 96 is attached to a side surface of the main body 84 via a holding member 94, and a lower end of the cylinder 96 is rotatably provided on an end portion of a damper 98. The damper 98 has a shape that covers the lower surface of the main body 84, is axially attached to the end of the holding member 94, and is rotated by the operation of the cylinder 96 to open and close on the lower surface of the main body 84. There is.

Next, a method of using this invention will be described. The kneaded clay W is supplied to the gypsum mold 8 mounted on the lathe shaft 6 of the ceramic molding machine 2, and the lathe shaft 6 and the iron 18 are rotated.

Then, the moving body 10 of the molding machine 2 is moved together with the support arm 12 from one side to the other side, and the support arm 12 is lowered, so that the iron 18 is lowered toward the kneaded clay W. Molding starts upon contact with W.

At the same time, the rod 72 is operated via the swing rod 74 by the action of the cam 78. When the rod 72 operates, the rotating member 24 attached to the rotating shaft 22 rotates, and the support shaft 26 follows and moves.

As the support shaft 26 moves in accordance with the rotation of the rotating member 24, the cutting blade 48 provided at the tip of the support rod 36 and the suction tube 64 provided at the tip of the support rod 52 are moved. A certain distance is set on the peripheral side of the plaster mold 8 and the surplus kneaded clay D derived from the peripheral side of the molded product is cut and approached to the molded product side for suction.

On the other hand, a suction source such as a vacuum pump or a blower is driven, and the opening 62 of the suction pipe 64 is brought into a suction state through the pipe 90 and the recovery unit 83.

While the molding is performed and the kneaded clay W is gradually processed as a molded product, the surplus kneaded clay D is derived from the peripheral portion of the molded product before the molded product is completely molded. The derived surplus kneaded clay D is cut by the cutting blade 48.

The potter's wheel shaft 6 is constantly rotating during molding, and the cutting blade 48 does not move, but the plaster mold 8 is rotating. Therefore, the surplus kneaded clay D of the kneaded clay W is subjected to the action of rotational stress. Be disconnected. The excess kneaded clay D is cut into a string shape, and the cut excess kneaded clay D is sucked by the centrifugal force acting on itself and the suction action acting on the suction pipe 64, and is collected in the collecting unit 83.

When the surplus kneaded clay D is completely recovered, the molded product from which the surplus kneaded clay D is removed is completely molded, and the trowel 18 is lifted to complete the molding.

At this time, the rocking rod 74, which was in contact with the cam 78 during molding, is released from the cam 78, so that the rod 72 returns to the position before the operation by the elastic force of the spring 80.

Therefore, when the molding is completed, the cutting blade 48 and the suction pipe 64 return to the positions before the molding.

The formed product is sent to the next step such as drying together with the gypsum mold 8. In this way, the surplus kneaded clay D is cut and collected from the molded product being molded.

The surplus kneaded clay D recovered by the recovery unit 83 is discharged downward by opening the damper 98 by the operation of the cylinder 96 provided in the recovery unit 83 for a certain period.
