Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate member processing apparatus for continuously processing plate members.

[0002]

2. Description of the Related Art Conventionally, in this type of processing apparatus, for example,
There is a device for processing a lenticular lens sheet used in a projection TV or the like. FIG. 11 is a diagram showing an example of a partial cross section of a general lenticular lens sheet. The lenticular lens 300 is provided with a lenticular lens element 302 in the vertical direction, and diffuses the light from the light source in the horizontal direction so that it can be observed in a wide range. Further, a light shielding portion 304 is provided in a portion of the light emitting surface where light does not go, so that reflection of external light is reduced and an image with good contrast can be obtained. Further, a lenticular lens element 306 such as a circle or an ellipse is accurately aligned and shaped to correct a color shift caused by projecting red, green, and blue light from different positions.

FIG. 12 is a diagram schematically showing a processing device for a lenticular lens sheet. Hereinafter, a conventional processing apparatus will be briefly described with reference to FIG. The extrusion molding machine 10 continuously extrudes an acrylic resin heated to a melting point or higher in a flat plate shape. Further, the roll forming machine 20 is one in which two cylindrical members each having a mold corresponding to the shape of the lenticular lens on the surface thereof are arranged so as to face each other on the cylindrical surface. The plate member 80 extruded from the extrusion molding machine 10 is still hot and is introduced between the cylindrical members of the roll molding machine 20 while having flexibility, and the shape of the cylindrical surface is transferred to the upper and lower surfaces thereof. As a result, the plate member 80 has a lens shape as shown in FIG. 11 on its upper and lower surfaces. In addition, the roll forming machine 20 changes the type of lens sheet to be manufactured,
It is replaced with one having a matching surface shape.

The cooling section 90 is a section for exposing the plate member 80 to the atmosphere and lowering its temperature. Plate member 80
Is cured in the cooling section 90 to be mechanically hardened until it has sufficient strength, whereby the lens shape transferred by the roll forming machine 20 is maintained.

The automatic thickness detecting device 30 irradiates the plate member 80 with ultrasonic waves and measures the time until the ultrasonic waves are reflected from the plate member 80 and returned to the plate member 80.
Is to detect the thickness of the. FIG. 13 shows an example of actual measurement values regarding the thickness of the plate member 80 obtained by the thickness automatic detection device 30. In the figure, the horizontal axis represents the widthwise distance of the plate member 80, and the vertical axis represents the thickness of the plate member 80. The automatic thickness detection device 30 has the advantage that the thickness of the plate member 80 can be measured nondestructively and in real time, but its measurement accuracy is low, and it is possible to confirm even the lens shape on the surface of the plate member 80. I can't. Therefore, the automatic thickness detection device 30 is used mainly for the purpose of early detection of an abnormal situation in which the thickness of the plate member 80 greatly changes.

The laminator device 40 is a device that covers the surface of the plate member 80 with a protective film made of resin. As a result, the plate member 80 can prevent the lens surface from being finely damaged. The laser cutters 50 and 60 cut the plate member 80 by irradiating the plate member 80 with laser light. The laser cutter 50 cuts the plate member 80 parallel to its traveling direction,
The laser cutter 60 cuts perpendicularly to the traveling direction. As a result, the plate member 80 is moved to the projection T
It is cut into a size corresponding to the screen of V (hereinafter referred to as "commodity size").

By the way, in the lenticular lens, in order to diffuse the light transmitted through the lens into a desired state, the distance between the incident side lens and the exit side lens and the relative position between the lenses are accurately measured. Needs to be well adjusted. Therefore, a part of the cut lens sheet is manually cut into smaller pieces (hereinafter referred to as “samples”) and used for inspection regarding the thickness of the lens sheet and the diffusion angle of transmitted light. The thickness of the lens sheet is measured by observing the cut surface of the sample with an optical microscope or a universal projector. On the other hand, the measurement of optical characteristics is about 60m
The measurement is performed by irradiating a sample cut into m squares with white light and measuring the intensity distribution of the light that passes through the lens sheet and diffuses. FIG. 14 is a diagram showing an example of measuring the optical characteristics of the lens sheet. In the figure, the horizontal axis represents the emission angle of light from the lens sheet, and the vertical axis represents the light intensity. As shown in the figure, the light intensity is applied to three colors of red (R), green (G), and blue (B), and each light has a certain light intensity or more over a certain angle range. The inspection is performed for whether or not

The inspection of the above optical characteristics is carried out on three samples taken from the central part of the screen of the projection TV and the left and right end parts. This is because this type of lens sheet has different optical characteristics, that is, different surface shapes, depending on the position of the screen so that the diffused state of the transmitted light is uniform over the entire screen. FIG. 15 is a diagram schematically showing the cross-sectional shape of different parts of the lens sheet. 15A is the left side of the screen when viewed from the projector side, and FIG. 15B is the central part of the screen.
(C) shows the part located on the right side of the screen. As shown in the figure, the line connecting the optical axes of the lens on the entrance side and the lens on the exit side of the lens sheet is perpendicular to the lens sheet in the center of the screen, and at both ends of the screen, different lines are formed in different directions. It is inclined at an angle, and the optical axis is designed so that the light intensity toward the front side is kept constant even at both ends of the lens sheet.

If the manufactured lens sheet is found to be defective as a result of the inspection of optical characteristics and the like, adjustments such as the distance between the cylinders of the roll forming machine 20 and the alignment in the cylinder axial direction are made based on the inspection result. After that, the lens sheet is manufactured and inspected again. As described above, in the conventional processing apparatus, the conditions for obtaining the lens sheet having the required quality are determined by repeating the manufacturing, inspection and adjustment of the lens sheet.

[0010]

However, in the above-mentioned conventional plate member processing apparatus, since the lens sheet which has reached the final stage of the processing apparatus is used for the inspection, it is considerable before obtaining the sample for inspection. It takes time. Since the plate member processing apparatus is continuously operated during that time, there is a problem that a large number of defective products are generated until the condition is set. Further, in recent years, a large variety of lens sheets have been produced in small quantities, and because the roll forming machine is frequently replaced, the proportion of condition conditions for the equipment accompanying this increases, and the occurrence of the above-mentioned defective products occurs.
There was a problem of increasing production costs. further,
Since the inspection of the optical characteristics and the like is performed using the lens sheet already cut into the product size, there is a problem that a good product may be destroyed and the yield of the product is reduced.

[0011]

That is, in the present embodiment, unlike the conventional case, it is not necessary to use a part of the lens sheet adjusted to the product size for inspection, so that the product yield is improved as compared with the conventional case.

Conventionally, when attempting to cut a part of a plate member such as acrylic, the plate member is liable to be cracked, so that the work must be done carefully and it is difficult to mechanize it. Was said to be. On the other hand, in the present embodiment, the problem is solved by disposing the sampling device 70 at a position immediately after being molded by the roll molding machine 20 and at which the plate member 80 is not yet completely cooled. ing. That is, at this position, the plate member 80 is sufficiently hardened to hold the molded lens shape, but at the same time holds a little elasticity, and when the pressure due to the punching operation of the sampling device 70 is applied. In addition, the pressure is absorbed by the elasticity of the plate member 80. Therefore, in this embodiment, it is possible to mechanically collect a sample for inspection without causing a crack in the plate member. Further, by mechanically performing the punching work of the sample in this manner, the state of the cut surface of the sample taken becomes more uniform than in the past, and the reliability of the inspection is improved especially when the thickness inspection is performed.
