Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an apparatus for processing plastic materials such as food materials, polymer materials, inorganic materials, and metal materials into plate shapes, and a processing method using this apparatus. It is.

(Prior Art) In order to obtain a wide plate material or to eliminate the anisotropy of the plate material, a method has conventionally been adopted in which the material is sequentially stretched vertically and horizontally between two working roller pairs.

However, this method is inefficient, and it is not desirable from the viewpoint of quality to move the material back and forth between the roller pairs many times. Furthermore, when two types of materials are overlapped and bonded between rollers to make a composite material, the material supply device becomes three-dimensional, which causes problems in terms of equipment structure and operation.

(Object of the Invention) The first object of the present invention is to provide an apparatus for obtaining a wide plate material while continuously advancing the material. A second object of the present invention is to provide an apparatus having a planar structure for obtaining a wide composite plate between rollers. A third object of the present invention is to provide a method for processing a plastic material into a plate shape using the apparatus. A fourth object of the present invention is to provide a processing method for a plate material that eliminates the anisotropy of the plate material.

(Means for Solving the Problems 9) The device of the present invention has nine actuating roller pairs (1) as shown in FIGS. 1 to 5.
A plate material characterized by being equipped with a guide (4) that guides and propels the plate material (3) by tilting it laterally with respect to the two machine centers (2) on the entry side of the machine, that is, on the upper side of FIGS. 1 and 3. The zero-actuation roller pair (1), which is a processing device, has the function of reducing the thickness of the plate material. In the conventional type of equipment in which the plate moves straight, about 90% of the reduction in plate thickness was due to an increase in length, and the remaining 10% was due to an increase in width.

On the other hand, when using the device of the present invention, if the direction in which the plate material enters from the machine axis is inclined by θ, the width of the plate material on the entry side will be 1, / cos θ times the true plate width, and θ will be In the case of 30 degrees, 45 degrees, and 60 degrees, the board width is 1.15 times, respectively.
1.41 times and 2.0 times. Therefore, the width of the plate after processing is approximately 1.1 times that of each of the two.

In this case, while processing the plate with the actuating roller pair (1), in order to keep the plate in a predetermined position and in an inclined state, the gap between the plate and the guide is almost eliminated, and multiple guides are driven to guide the plate. A guide (4) is required.

The guide (4) that is guided and propelled moves into the machining area (
5) This state-of-the-art guide has the function of accurately determining the position and width of the plate after processing. It is also desirable that this guide be driven to help advance the plate and have sufficient strength to shape the plate to a target thickness.

The guided and propelled guides (4) can be arranged in pairs at substantially symmetrical positions with respect to the machine center (2), as shown in FIG. This device simultaneously feeds the same or different materials from the left and right sides and joins them using a pair of operating rollers.
It can be used when obtaining a composite plate. In this device, it is sufficient that there is a gap between the plates to allow the movement of both, and the entry side devices including the guide equipment can be arranged almost flat.

The actuating roller used in the device of the present invention is preferably in the shape of a truncated cone, and the actuating roller pair is arranged such that the outer side (3a) of the plate material is in contact with the larger diameter side, and the inner side (3b) of the plate material is in contact with the smaller diameter side. Set up When the plate material enters from one side, as shown in FIGS. 1 and 2, the roller diameter is arranged so that it becomes larger on the outer circumferential side of the plate material. When the plates enter from both sides, as shown in FIGS. 3 and 4, the actuating rollers are arranged so that the diameter becomes larger on the outer circumferential side of each plate. By arranging the actuating rollers in this manner, it becomes easier to widen and roll the plate material.

In the present invention, 9
When processing a plate using a processing device equipped with a guide (4) that guides and propels the plate by tilting the plate 3) laterally with respect to the machine center (2), the guide load on the outer circumference of the plate is P0, When the guide load on the inner side of P1 is P1, the circumferential speed of the guide is VG, and the reference position circumferential speed of the operating roller is VR, then P.

/ If P+ is larger than the target value, perform an operation to decrease VG/VR, and if P0/P1 is smaller than the target value, perform an operation to increase VG/VR to make P0/P1 match the target value. Let it be processed. Here, the kite load can be represented by the one or two guides closest to the actuation roller. When the guide load on the outer side decreases, the kite load on the position side increases, and P0/P1 becomes smaller. In this case, the amount of plate material flowing in on the outer side is insufficient, and it can be returned to the target value by increasing VG/VR. Target values are determined in advance based on experience.

The processing method of the present invention is effective in improving anisotropy in materials that are produced by processing. In other words, in a device in which the guides (4) guided and propelled on the entry side of the actuating roller (1) are arranged in pairs at approximately symmetrical positions with respect to the machine center (2), the material becomes anisotropic due to processing. are guided by guides on both sides, and are superimposed and joined by two actuating roller pairs to obtain a composite material in which anisotropy is canceled.

The causes of the anisotropy of the plate material include the deflection of elongated air bubbles, the deflection of polymer chains, the deflection of crystal grain length, the deflection of metal texture, etc. 9. There are deflections in reinforcing fibers.

The method of the present invention is effective for eliminating all of these anisotropies or dispersing the strength in the desired direction. (Effects of the Invention) As described above, the present invention allows the material to progress continuously. However, it is possible to obtain a device that can obtain a wide plate material. Furthermore, it is possible to provide an apparatus having a planar structure for obtaining a wide composite plate between rollers. Furthermore, the device can be used to process plastic materials into plate shapes. Furthermore, a method for processing a plate material that eliminates anisotropy in the plate material can be provided.

(Field of Application of the Invention) The method of the present invention opens a new way as a processing method for plastic materials such as foodstuffs, daily necessities such as polymer materials, inorganic materials, and metal materials, and industrial products. It became possible to provide equipment. Generally, materials become more anisotropic through processing.

In particular, materials containing reinforcing fibers exhibit remarkable anisotropy.

The apparatus and processing method of the present invention can be applied to all of these plastic materials.
