The cutter portion (5a) is composed of a cutter holding portion (52) and a cutter (51), but in the present embodiment, the cutter (51) uses a spiral spring wire material. Further, the installation positional relationship between the transfer conveyor (3) and the cutting device (5) is set so that the transfer conveyor (3) penetrates the space between the cutter (51) of the cutting device (5) and the rotary plate (6). Has been done.

Now, the cutter control mechanism will be described in detail. In FIG. 3, an up-and-down moving plate (9) is provided above a substrate (10) supported by four legs, and the up-and-down moving plate has guides (84) at four corners. (4) is vertically movably inserted into the guide holes (101) provided at the four corners of (1) to enable vertical movement parallel to the substrate (10). The vertical movement plate (9) is controlled in vertical movement by the rotation of the cams (92, 93) having a required shape provided on the substrate (10). The cams (92, 93) are on the substrate (10).
It is driven by the pulse motor (91) provided above.

Next, a support shaft (82) is provided in a central portion of the upper surface of the vertical moving plate (9) at a position orthogonal to the longitudinal direction of the vertical moving plate, and the swing plate (8) is attached to the support shaft (82). Attach it so that it can swing back and forth. The reciprocating swing is controlled by the rotation of a cam (83) provided on the vertical moving plate (9). Cam (83)
Is a pulse motor (8) provided on the vertical moving plate (9).
Driven by 1). Further, a lateral movement plate (7) is provided above the swing plate (8). The lateral movement plate (7) is a sliding guide rail (7) mounted on the rocking plate (8).
2) Holds at (72) and makes a reciprocating lateral movement. At the end of the lateral movement plate (7), there is an elongated hole (7) in the width direction of the lateral movement plate (7).
3) is provided, and the tip of the crank driving rod (74) is inserted into the elongated hole, and the crank driving rod (74) is rotated by a pulse motor (71) to perform a lateral reciprocating motion. The crank driving rod (74) and the pulse motor (71) are installed on the rocking plate (8).

Furthermore, a rotation support shaft (62) is provided on the upper surface of the lateral movement plate (7) perpendicularly to the upper surface, and the rotation plate (6) is reciprocally attached to the rotation support shaft. An elongated hole (63) is provided in the longitudinal direction of the rotating plate (6) near the center of the tip of the rotating plate (6), and the distal end of a crank driving rod (64) having the same shape as the lateral moving plate (7) is provided in the elongated hole. The part is inserted, and the rotary plate (6) performs reciprocating rotary motion by rotating the part by the pulse motor (61). The crank driving rod (64) and the pulse motor (61) are installed on the lateral moving plate (7). The cutter holding part (52) is fixed to the upper surface of the rotary plate (6), and the cutter holding part (52) is fixed.
The cutter (51) is set in the.

The above is the specific construction of the cutter control mechanism in this embodiment. Now, the transport conveyor (3)
The prismatic porcelain clay material (2) advancing by is cut in the longitudinal direction by the cutting device (5) which operates according to the data previously input to the integrated control device (not shown). At the time of cutting, it is possible to activate all the exercise plates, or select and activate the exercise plates as needed. Further, the moving speed of each moving plate is controlled by driving the respective pulse motors in accordance with the instruction of the total control device which has previously input data.

Now, a case where only the rotary plate (6) and the lateral moving plate (7) of the respective motion plates are operated will be described. Since the rotary plate (6) reciprocally rotates about the rotary shaft (62), one of the cutters (51) moves forward and the other moves backward with the rotary shaft (62) as a boundary. The forward movement and the backward movement are switched according to the rotation of the crank drive rod (64). Therefore, the left and right cut surface shapes of the relief-shaped ceramic plate are changed each time. If the motion function of the lateral movement plate (7) is added to this, the cutter (51) is further subjected to reciprocal lateral movement motion, so that the cutting surface shape has waviness.

Further, if the pulse motors (61, 71) are rapidly rotated according to an instruction from the general control device, a sharp deviation in shape will be added. Thus, the forward speed of the columnar clay material (2), the reciprocating rotation speed of the rotating plate (6), the reciprocating rotating range, and the reciprocating moving speed of the lateral moving plate (7),
In addition, by controlling the moving range, a relief-like ceramic plate having a required surface shape can be obtained. Here, the reciprocating rotation range,
In addition, the range of reciprocating lateral movement is the crank drive rod (64, 74)
It can be freely changed by adjusting the lengths of the horizontal arm portions (65, 75). Furthermore, the reciprocating swing range of the swing plate (8),
The vertical movement range of the vertical movement plate (9) also includes the cams (83, 92, 9).
It can be easily changed by changing the shape of 3).

The mechanism for driving the respective motion plates (6, 7, 8, 9) in the above cutting device (5) is not limited to the above-mentioned embodiment, but has a constitution for exhibiting similar motion functions. Anything is acceptable as long as it is. For example, it is easily possible to drive the motion plate by a ball screw instead of by a cam. Further, the position of the rocking plate support shaft (82) on the vertical moving plate (9) and the rotation plate support shaft (6) on the lateral moving plate (7).
It is possible to obtain a more complicated motion by shifting the position of 2) and installing it. Further, by setting the cutting device (5) as a whole to stand upright with an inclination of 90 degrees, the prismatic clay material (2) can be extruded in a vertical position and formed into two pieces. The post process becomes easy. In this case, since the cutter (51) is placed vertically and the existence of the conveyor (3) becomes an obstacle, the conveyor (3) is divided into two at the cutting device installation location.

The prismatic porcelain clay raw material (2) cut by the cutting device (5) is conveyed to the press cutting machine (4) by the conveying conveyor (3) and press-cut. The blade (41) of the press cutting machine in this example is a straight type, and the prismatic clay material (2) is press-cut into the rectangular parallelepiped-shaped ceramic clay block (21).
For example, if a zigzag blade is used, a clay pot with zigzag ends can be obtained. Here, since the prismatic clay material (2) is press-cut while advancing, the press cutting machine (4) also presses and advances at the same speed as the prismatic clay material (2), and every time one press ends. In addition, it has a structure (not shown) that returns to the basic position. The cut ceramic earth block (21) is sent to a post-process and is sequentially divided into two relief-like ceramic plates (22, 23), which are subjected to processing such as drying, chemical treatment, firing and the like. The above is a specific description of the present embodiment.

[0021]

According to the present invention, it is possible to obtain a relief-like porcelain plate having an extremely complicated surface shape because it is possible to select a free movement in which the porcelain clay material to be extruded is variously changed and cut along the layer during extrusion. be able to. Further, since these movements are given by the data inputted to the integrated control device in advance, they are reproducible and the data can be stored very easily. Furthermore, since the type of data and the length of the data are flexible, it is possible to carry out high-mix low-volume production, which is uncomparable with conventional products. Furthermore, since it is a continuous production system that does not rely on human power and its equipment, not only has it made a marked progress in terms of the working environment, but has also dramatically increased productivity.
