An example of the supply side conveyor device 61 is configured by the above 62 to 67 and the like, and an example of the discharge side conveyor device 81 is configured by 82 to 87 and the like.

  The supply-side lifting cradle 71 provided at the location of the supply-side conveyor device 61 and the discharge-side lifting cradle 91 provided at the location of the discharge-side conveyor device 81 have the same configuration, and the box body transport path A A pair of receiving bodies 72, 92 disposed at a predetermined interval in the direction of is connected to the upper ends of elevating bodies 74, 94 from elevating operation sections 73, 93 disposed on the floor F side, respectively. It is composed of that. In addition, at the outer end of the upper surface of the receiving bodies 72 and 92 in the direction of the box body transport path A, positioning that acts on the lower part of the box body 11 when the receiving bodies 72 and 92 and the box body 11 are relatively close to each other. Members 75 and 95 are provided at a plurality of locations, respectively. Here, the positioning members 75 and 95 are of a type in which the roller is freely rotatable or a type in which the round rod body is disposed sideways and fixed by welding or the like. The lower part of the box body 11 is guided and then positioned.

  At that time, the pair of receiving bodies 72 (92) can support the box body 11 having a predetermined width 11W in the direction of the box body transport path A, that is, an outer end width 72W (92W), that is, [11W <72W (92W). )] And the transfer means 111 is set to a width 72S (92S) between which the inner end can operate freely. Furthermore, the length 72L (92L) in the orthogonal direction B of the receptacle 72 (92) is shorter than the inner end face width 61SW (81SW) of the conveyor device 61 (81), that is, [72L (92L) <61SW ( 81SW)]. The above-described 72 to 75 and the like constitute an example of the supply-side lift cradle 71, and 92 to 95 and the like constitute an example of the discharge side lift cradle 91.

  The feeding device 101 provided in front of the processing means 20 is for conveying (supplying) the glass substrates 1 one by one in a manufacturing process (manufacturing line), for example, and is composed of a belt type or a roller type. The surface 101a has the same level as the transport surface 31a of the transport device 31. The transfer means 111 provided on the side opposite to the feeding device 101 includes, for example, a movable body 112 movable on a fixed path 115 formed between the processing means 20 and the conveyor devices 61 and 81, and An example thereof is constituted by the elevating part 113 provided on the moving body 112 and the fork part 114 provided on the elevating part 113 so as to be movable in and out in the lateral direction. At that time, the fork width 114W of the fork portion 114 is shorter than the inner end width 72S (92S) of the pair of receiving bodies 72 (92), that is, [114W <72S (92S)].

  Accordingly, the transfer means 111 is configured to move the fork unit 114 up and down through the lifting unit 113 and the lateral movement of the fork unit 114 in a combined manner, so that the supply side lifting platform 71 and the discharge side lifting platform 91 are moved. The box body 11 is configured to be freely transferred.

Hereinafter, the operation in the first embodiment will be described.
As shown in FIG. 4, the transfer means 111 supports the box body 11 on the fork part 114, and here, the glass substrate 1 is vertically spaced from the box body 11 via a support member 15 at a predetermined interval. Is stored in multiple stages. By this transfer means 111, the actual box body 11 is handed to the supply-side lift cradle 71. At this time, as shown in FIG. The raising / lowering body 74 is raised by the above-described operation so that the receiving body 72 is positioned above the conveyance support surface 61a of the supply-side conveyor device 61. In the processing means 20, the conveyance device supports and supports the processing-side conveyor device 52 by the elevation device 41. The surface 52 a is positioned slightly above the transport surface 31 a of the transport device 31 and is at the same level as the transport support surface 61 a of the supply-side conveyor device 61.

  Therefore, after the transfer means 111 that has been moved on the fixed path 115 is stopped facing the supply-side lift receiving base 71, as shown in FIG. The actual box body 11 supported by the fork part 114 can be transferred onto both the receiving bodies 72 by projecting between the receiving bodies 72 and lowering the elevating part 113. At that time, the fork portion 114 has a fork width 114W shorter than the width 72S between the inner ends of the receiving body 72, so that the protruding and lowering can be performed without any trouble. After that, as shown in FIG. 9, the fork part 114 is retracted and stored on the elevating part 113.

  Thus, when the actual box body 11 is transferred onto the both receiving bodies 72, the both receiving bodies are caused by an error in the stop position of the transfer means 111, an error in the support position of the actual box body 11 by the fork 114, or the like. 72, when the actual box body 11 is about to be delivered in a misaligned state in the direction of the box body transport path A, immediately before the actual box body 11 is delivered, the lower portion on the misalignment side of the actual box body 11 is positioned correspondingly. The guide can be guided by the inwardly arcuate circumferential surface of the member 75, so that the positional deviation in the direction of the box body conveyance path A can be automatically corrected and positioned in the corrected posture.

  Thus, with the actual box body 11 supported by the both receiving bodies 72, the receiving body 72 is lowered by the reverse operation of the lifting operation section 73, and is positioned below the transport support surface 61 a of the supply-side conveyor device 61. By doing so, the actual box body 11 supported by the two receiving bodies 72 of the supply side elevation receiving base 71 can be transferred onto the transport support surface 61 a of the supply side conveyor device 61. At that time, since the length 72L in the orthogonal direction B of the receiving body 72 is set to be shorter than the inner end face width 61SW of the both supply side conveyor devices 61, the downward movement can be performed without any trouble. Further, since the maximum width 61LW in the orthogonal direction B of both the supply side conveyor devices 61 is set to be larger than the width 11W of the box body 11, the support of the box body 11 between the supply side conveyor devices 61 is stable. You can do it.

  Further, when the actual box body 11 is supported in a state of being displaced in the orthogonal direction B with respect to both the receiving bodies 72, the actual box body 11 is conveyed by the supply-side conveyor device 61 by the lowering of the receiving body 72. Immediately before passing on the support surface 61a, the lower part of the actual box body 11 on the position shift side can be guided by the corresponding spherical body 65 group, so that the position shift can be automatically corrected and positioned in the corrected posture. obtain. That is, as shown by the solid line in FIG. 1, the lower portion of the lower rectangular frame 12 of the actual box body 11 is in contact with the exposed spherical surface of the sphere 65 from above, and the lowering force is applied to the support member 66 by the descending force. On the other hand, by guiding the lower rectangular frame 12 while rotating the sphere 65 downward, as shown by the phantom line in FIG. 1, the position deviation in the orthogonal direction B is automatically corrected, It can be supported by the rollers 64 of the supply-side conveyor device 61.

  In this manner, the supply-side conveyor device 61 and the processing-side conveyor device 52 are driven synchronously while the actual box body 11 is positioned and supported in the supply-side conveyor device 61. As a result, the actual box body 11 can be supplied and transported by the supply-side conveyor device 61 on the box-body transport path A, and can be received and transported by the processing-side conveyor device 52. As shown in FIGS. 6-8, it can be located in the frame main body 21 through the insertion side open part 21b.

  At this time, the outer surface of the lower rectangular frame 12 on the position shift correction side is brought into contact with the exposed spherical surface of the sphere 65 from the inner side, so that the supply and conveyance by the supply-side conveyor device 61 is supported by the support member 66. In contrast, the lower rectangular frame 12 is guided while rotating the sphere 65 to the horizontal direction (lower side), and as shown in phantom lines in FIG. Supply and conveyance can be performed without shaking (displacement) in the direction of the orthogonal direction B.

  Thereby, when the actual box body 11 is supplied onto the box body transport path A by descending, the spherical body 65 is guided while being rotated downward with respect to the support member 66, thereby automatically correcting the misalignment. When the actual box body 11 is supplied and conveyed by the supply-side conveyor device 61, the spherical box 65 is guided while being rotated with respect to the support member 66 in the horizontal direction. The body 11 can be supplied and conveyed smoothly without shaking (displacement). That is, although the structure is simple and inexpensive that also serves as the sphere 65, correction of the positional deviation of the actual box body 11 and smooth supply and conveyance can always be suitably performed.

Moreover, the spherical body 65 is exposed to 90 ° or more θ ₁ in the conveyance direction as viewed from the support member 66, and is exposed to 90 ° or more θ ₂ in a state of being distributed back and forth with respect to the center line 65a in plan view. Thus, the spherical body 65 is suitably exposed to the support member 66, and the actual lowering and transport guidance of the box body 11 can be accurately performed, and the rotational support of the spherical body 65 by the support member 66 is stable. Can be done.

The spherical body 65 is disposed with its center 65b positioned above the conveyance support surface 61a, so that the conveyance guide position (contact position) of the sphere 65 is above the conveyance support surface 61a and the guidance is always stable. Can be done. Further, the box body conveyance path A is formed by the group of rollers 64, and the spherical body 65 is disposed between the rollers 64, so that the spherical body 65 can be disposed in a compact manner via the support member 66. it can.

  As described above, the actual box body 11 is received and conveyed by the processing-side conveyor device 52, and the supply-side conveyor device 61 or the like is detected by detecting that the actual box body 11 is located at a predetermined position in the frame body 21 by the appropriate detection means. The drive of the process side conveyor apparatus 52 is stopped. And the actual box body 11 currently supported by the conveyance support surface 52a can be lowered | hung by lowering the process side conveyor apparatus 52 by the action | operation of the raising / lowering apparatus 41. FIG.
