Description

  The present invention relates to stereoscopic glasses and a method for manufacturing the same.

  Conventionally, two-color films that have a complementary color relationship, such as a red film (left-eye film) and a blue film (right-eye film), are generated for two types of color systems, red and blue. In addition, anaglyph-type stereoscopic glasses are known in which a stereoscopic effect is obtained by observing a stereoscopic image (stereo pair image) including a right-eye image and a right-eye image. It is used as novelty goods.

  However, in conventional stereoscopic glasses, left-eye and right-eye films are separately prepared, and it is necessary to individually fix the left-eye and right-eye films to the frame material. For this reason, in order to manufacture the conventional stereoscopic glasses, many work steps are required. For example, as shown in FIGS. 10 (A) to 10 (E), an operation of making a hole in the frame material (FIG. 10 (A)), a gluing operation of the film (FIGS. 10 (B) and 10 (C)). The frame material is bent (FIGS. 10D and 10E), and the frame material is fixed (FIGS. 10D and 10E). These operations are difficult to perform on a series of lines, and each operation is likely to be divided, and often involves manual operations that increase costs. For this reason, stereoscopic glasses that can be manufactured at a low cost suitable for supplements and novelty goods are desired.

At this time, with respect to the left-eye film 12 pulled out from the first reel 12a, the pattern of the index mark 18 was transferred at a predetermined interval in the drawing direction of the left-eye film using the printing roller 42, and the pattern was transferred. The index mark 18 is printed by curing the ink by irradiating the film with ultraviolet rays by the ultraviolet irradiation device 44. This printing step is preferably performed in a state where the film is flat. Specifically, it is preferable to perform the printing step before performing the bonding step between the left-eye film 12 and the right-eye film 14 to be dictated. The index mark 18 may be attached by embossing or sticking a sticker on which the index mark 18 is printed. In this case, the stamping process and the sticking process of the seal are also included in the printing process in a broad sense in this method. Further, the index mark 18 may be attached to the right eye film 14 instead of the left eye film 12, and furthermore, the index mark may be attached to both the left eye film 12 and the right eye film 14.

  Subsequently, while pulling out the left-eye film 12 and the right-eye film 14 from the first reel 12a and the second reel 14a, the double-sided tape 16 pulled out from the third reel 16a is used as the left-eye film 12 and the right-eye film 14. And the two films are pressure-bonded (adhered) by the pressure-bonding roller 46. At this time, the film for left eye 12 and the film for right eye 14 may be fused (adhered) with heat.

  Next, the film adhesive 19 composed of the left-eye film 12 and the right-eye film 14 is pulled out of the left-eye and right-eye films 12, 14 from the first and second rolls 12a, 14a. Using a punching mold 50 attached at a predetermined interval with respect to the direction, the first stereoscopic glasses 1 are cut into a shape with a press. The first stereoscopic glasses are operated at predetermined intervals in the drawing direction of the left-eye and right-eye films 12 and 14 from the film adhesive 19 by operating a press machine at a predetermined period using one punching die 52. One piece may be cut.

  Here, when the film adhesive 19 is cut using the punching mold 50, the number of index marks 18 printed on the left-eye film 12 is counted (counted) by a given sensor (not shown). Thus, on the condition that the number of index marks 18 corresponding to the number of punching dies 50 attached to the punching die frame 50 is detected, the drawing operation of the film adhesive 19 is temporarily stopped, and the first stereoscopic glasses 1 Can be cut into pieces. In this way, the timing for cutting the film adhesive 19 with the punching mold 50 can be obtained based on the number of detected index marks 18, so that the work process can be automated and the cost can be reduced. Can do.

  Further, when the film adhesive 19 is cut, the number of pieces cut from the film adhesive 19 may be counted (counted) based on the number of detected index marks 18 as in the case described above. In this way, the production number can be easily managed, and the production cost can be further reduced.

  As described above, according to the manufacturing method of the present embodiment, each film is bonded while the left-eye film 12 and the right-eye film 14 are pulled out together, and then the first film composed of one film adhesive is used. These manufacturing steps can proceed in a series of lines until the stereoscopic glasses 1 are cut. For this reason, a large amount of stereoscopic glasses can be produced at low cost. Further, in the manufacturing method of the present embodiment, by attaching the films 12 and 14, the individual pieces of the film adhesive 19 can be made strong as the first stereoscopic glasses 1, and a reinforcing member such as a frame material can be obtained. It is not necessary to prepare the device, and the cost can be reduced.

(Modification)
FIG. 4 shows a modification of the first stereoscopic eyeglass manufacturing method. In the following, description common to the example shown in FIG. 3 will be omitted, and main differences from the example shown in FIG. 3 will be described.

  In the manufacturing method of this example, a first reel 12b in which a wide film is wound on the left eye film 12 and a second reel 14b in which a wide film is wound on the right eye film 14 are used. . And when using this for the manufacturing method of the 1st stereoscopic eyeglasses 1, after pulling out each film from the 1st reel 12b and the 2nd reel 14b using the cutter 41, cut | disconnecting by predetermined width, These steps can be performed.

  Here, in the manufacturing method of this example, when the film is pulled out from the first roll 12b and the second roll 12b while cutting the film, an excess portion of the film that is not used in the subsequent process is removed from the fourth reel 12c ( It is preferable to wind up with the other reel) and the fifth reel 14c (other reel). In this way, after the first roll 12b and the second roll 14b are used up, the next production is immediately performed by using the fourth reel 12c and the fifth reel 14c wound up with the surplus portions. It can be reused in the process, and the first stereoscopic glasses 1 can be produced at low cost.

2-1. Method for Producing Second Stereoscopic Glasses FIGS. 5 to 9 show an example of a method for producing the second stereoscopic glasses 2 according to the present embodiment.
