Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface leveling device for leveling the surface of a plate. 2. Description of the Related Art For example, conventionally, as one method of manufacturing a plate-shaped plastic plate, there is a case in which a liquid plastic material is sprayed or poured into a mold at room temperature to be cured and molded. When many air bubbles remain in the plastic plate and become a product, the strength may be insufficient or water leakage may occur. [0003] Therefore, it is necessary to forcibly remove bubbles contained in the plastic plate during the semi-cured state before completion.
Conventionally, to remove these bubbles, a person holds a rotating roller and rotates the roller while pressing it against a plastic plate, while adjusting the pressing force by comprehensively considering the movement of the wrist, feeling of force, visual judgment, etc. Defoaming process is performed. [0004] However, when the roller is hung by human power, the pressing force and the like vary from person to person, and the product is likely to be uneven. Of people have to work on the roller at the same time, which is extremely impossible. In addition to defoaming plastic plates,
No appropriate mechanism is known for various surface leveling devices such as painting. SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic leveling apparatus which can perform roller hanging on a plate surface. According to the present invention, there is provided a surface leveling apparatus for pressing a plate body surface while rotating a cylindrical roller, the surface leveling device comprising: A first drive unit that moves in a plane direction of the plate body surface, a second drive unit that drives in a direction intersecting with the plate body surface is provided;
An arm is attached to the drive unit in a direction inclined with respect to the plate body surface, a part of the arm is formed by a plate spring , and the roller is rotatably attached to a tip of the arm, and the arm is attached to the arm. A sensor for detecting an applied force is provided, and a driving device of the second driving unit is adjusted based on an output of the sensor. In the surface leveling device having the above-described structure, a spring member is attached to a part of the arm provided at an angle, and a rotary roller is attached to the tip through the spring member.
The roller can press the plate surface smoothly, and the force applied to the roller by the force sensor can be adjusted, so that it can freely follow the shape of the plate surface and automatically with extremely efficient and uniform force. Work can be done. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the illustrated embodiments. In FIG. 1, a table 2 supported by a fixed frame 1 movable in the X-Y direction is provided with a drive mechanism 3 composed of, for example, a cylinder which can move up and down, and has a lower end with an arm in an oblique direction. 4 is attached via an angle setting mechanism 5. The angle of the arm 4 is selected according to various conditions, and can be arbitrarily adjusted by the angle setting mechanism 5. For example, about 30 degrees with respect to a horizontal plane is preferable. An intermediate portion of the arm 4 is constituted by a leaf spring 6, and a cylindrical roller 7 is rotatably attached to a tip portion of the arm 4. Arm 4
Is provided with a force sensor 8 so that the force applied to the roller 7 can be measured. In using this apparatus, a roller 7 is used.
Is placed on the surface of the plastic plate P on the surface plate, the XY table 2 is driven to reciprocate in the X direction, which is the rotation direction of the roller 7, and the surface of the plastic plate P is pressed while rotating the roller 7. To expel remaining air bubbles inside. At this time, the force applied to the roller 7 is detected by the force sensor 8 and the vertical position of the lower surface of the dynamic drive mechanism 3 and the arm 4
The force is kept constant by controlling the rotation angle of. Further, as the roller 7 rotates, the leaf spring 6 serves as a buffer member for applying a substantially constant force to the roller 7, and can sufficiently follow the shape of the plastic plate P, for example, a corrugated portion. Become. In this case, since the arm 4 is inclined, an excessive reaction force from the plastic plate P is prevented from being applied to the roller 7. Further, the leaf spring 6 corresponds to adjustment by a human wrist, and serves to absorb a fluctuation in force due to bending, and can also absorb a twisting force and the like. When one row of defoaming processing by reciprocating motion in the Y direction is completed several times, the driving mechanism 3 raises the roller 7 and the XY table 2 moves the driving mechanism 3 and the arm 4 in the Y direction, and the next Repeat degassing of the row. By changing the length of the roller 7 in the axial direction, the width of one row capable of defoaming can be arbitrarily changed. Further, by attaching a strain gauge 9 or the like to the leaf spring 6 and detecting the strain force applied to the leaf spring 6 and adjusting the attachment angle of the arm 4, finer control is also possible. Although the above-described embodiment has been described with respect to the defoaming treatment of plastic, it can also be used for other painting work, for example, and can perform leveling even if the plate body surface is vertical. . In addition, the plate surface to be leveled also includes a cylindrical surface having a large diameter. As described above, the surface leveling device according to the present invention automatically and efficiently adjusts the surface of the plate body by controlling the force using the roller attached via the spring member. Moreover, it can be leveled with a uniform force.
