Further, the glass plate disposal device according to the present embodiment is provided downstream of the manufacturing device 1.

  In the manufacturing apparatus 1, the glass Gm melted in the melting furnace 2 flows into the float bath 3. Then, in the float bath 3, the molten glass Gm flows while floating on the molten metal (tin) M in the float bath 3 to form a smooth glass plate G. Then, the glass sheet G is sent to the annealing furnace 4 where it is gradually cooled, and thereafter, is conveyed by the conveying device 6 composed of a plurality of conveying rolls 5, cut into a predetermined size and sent out.

FIG. 2 is a schematic side view illustrating the glass sheet disposal apparatus according to the present embodiment.
As shown in FIG. 2, the glass sheet disposal device 10 according to the present embodiment includes a crushing mechanism 20, a hopper 30, and a scriber 40. The crushing mechanism 20, the hopper 30, and the scriber 40 are provided in the middle of the transporting device 6 that transports the band-shaped glass plate G sent from the manufacturing apparatus 1 in the transporting direction A. The scriber 40 is arranged on the upstream side, and is arranged on the upstream side of the hopper 30.

FIG. 3 is a schematic diagram illustrating a crushing mechanism.
As shown in FIG. 3, the crushing mechanism 20 includes a pair of metal rolls 21 that pinch and send the glass plate G from above and below, and crush the glass plate G sent by these holding rolls 21 while rotating. And a hammer roll 22 to be formed. In the crushing mechanism 20, the glass plate G is crushed by the hammer roll 22, is turned into cullet C, and is discarded.

  As shown in FIG. 2, a protection cover 25 is provided upstream of the crushing mechanism 20. The protective cover 25 is formed of, for example, a metal plate such as iron or stainless steel, and is formed in a concave shape having an upper surface plate 27 and side plates 28 extending downward from both edges of the upper surface plate 27. ing. In the protective cover 25, a space portion surrounded by the upper surface plate 27 and the side surface plate 28 is defined as a housing space S. In the housing space S, two transport rolls 5a adjacent to the transport device 6 can be stored. It has been. The protective cover 25 is disposed above two transport rolls 5a adjacent to the upstream side of the crushing mechanism 20 with the opening side facing downward. The protective cover 25 can be raised and lowered, and can be moved between a standby position, which is a position above the transport rolls 5a, and a protection position, which is lowered from the standby position and stores the two transport rolls 5a in the storage space S. Be moved. When the protective cover 25 is disposed at the protective position and the transport roll 5a is stored in the storage space S, the upper and both sides of the transport roll 5a are covered by the protective cover 25.

FIG. 4 is a schematic diagram showing the shape of the protective cover.
As shown in FIG. 4, the protective cover 25 has a guide surface 29 at a corner between the top plate 27 and the side plate 28. The guide surface 29 is gently inclined upward with respect to the transport direction A of the glass plate G by the transport device 6.

  As shown in FIG. 2, the transport roll 5b adjacent to the downstream side of the crushing mechanism 20 can be moved up and down. By moving up and down, the transport roll 5b is disposed at the same height as the other transport rolls 5, and moves from the normal position at which the glass sheet G can be transported to the normal position, and deviates from the normal position. It is possible to move between the evacuation position.

  As shown in FIG. 2, the hopper 30 provided on the upstream side of the crushing mechanism 20 includes a plurality (four in this example) of movable rolls 31. The hopper 30 having these movable rolls 31 is entirely lowered with respect to the transport direction A of the glass sheet G transported from the upstream side by lowering the downstream side around the axis of the movable roll 31 at the upstream end. It is tilted downward (see the two-dot chain line in FIG. 2). Thus, the glass sheet G conveyed from the upstream side can be sent obliquely downward.

  The scriber 40 provided upstream of the hopper 30 includes a scribing wheel 41 that moves in the width direction of the glass plate G. Then, in the scriber 40, the scribing wheel 41 moves in the width direction of the glass sheet G, thereby forming a crack in the glass sheet G.

  The glass sheet manufacturing apparatus 1 manufactures a strip-shaped glass sheet G in a normal operation. In addition, when performing maintenance or the like, the manufacturing apparatus 1 performs a discarding operation in which the glass sheet discarding apparatus 10 discards the belt-shaped glass sheet G sent from the upstream without interruption.

Next, the shift from the normal operation to the disposal operation in the manufacturing apparatus 1 will be described.
FIG. 5 is a diagram for explaining the operation of the glass plate disposal device, and (a) to (c) are schematic side views of the glass plate disposal device.

  As shown in FIG. 5A, cracks are formed by the scriber 40 on the strip-shaped glass sheet G sent from the manufacturing apparatus 1 for the glass sheet G. In addition, the hopper 30 is movable and tilted. Then, the fed glass sheet G is cut at a crack formation location by its own weight, and is sent downward from the hopper 30. As a result, the belt-shaped glass sheet G sent from the manufacturing apparatus 1 is cut into a predetermined length below the normal conveyance direction A and sent out.

  As shown in FIG. 5B, while the glass plate G is being fed downward by the hopper 30, the protection cover 25 at the standby position is lowered and placed at the protection position. Thereby, the two transport rolls 5a adjacent to the upstream side of the crushing mechanism 20 are accommodated in the accommodation space S of the protective cover 25, and the upper side and both sides are covered. In addition, with the lowering of the protective cover 25, the transport roll 5b at the normal position adjacent to the downstream side of the crushing mechanism 20 is raised and arranged at the retracted position.

  When the lowering of the protective cover 25 and the raising of the transport roll 5b are completed, the hopper 30 is arranged at the normal transport position, and the operation of forming the crack on the glass plate G by the scriber 40 is stopped.

  Then, as shown in FIG. 5C, the band-shaped glass plate G sent from the manufacturing apparatus 1 passes through the hopper 30, rides on the protective cover 25 covered by the transport roll 5a, and is sent to the crushing mechanism 20. . At this time, since the guide surface 29 is formed at the corner between the upper surface plate 27 and the side surface plate 28 on the protective cover 25, the glass plate G slides on the guide surface 29 and is contacted with the upper surface of the protective cover 25. It is guided smoothly to the side (see FIG. 4).

  In the crushing mechanism 20, the holding rolls 21 move in directions approaching each other, and rotate in opposite directions while holding the glass plate G. Thereby, the glass plate G is sent out to the rotating hammer roll 22. Then, the glass plate G is crushed by the hammer roll 22 to be cullet C and discarded.

  At this time, in the crushing mechanism 20, the fine cullet C of the glass plate G crushed by the hammer roll 22 scatters to the upstream side and the downstream side. However, in the glass sheet disposal device 10, the transport roll 5a on the upstream side of the crushing mechanism 20 is covered by the protective cover 25, and the transport roll 5b on the downstream side of the crushing mechanism 20 is disposed at the upper evacuation position. Therefore, damage caused by the fine cullet C of the scattered glass plate G adhering to the transport rolls 5a and 5b is suppressed.

  As described above, according to the glass sheet discarding apparatus 10 according to the present embodiment, the protective cover 25 that covers the transport roll 5a adjacent to the upstream side of the crushing mechanism 20 is detachable. Therefore, when the glass plate G is crushed by the crushing mechanism 20, the transporting roll 5 a adjacent to the crushing mechanism G is covered with the protective cover 25, so that damage to the transporting roll 5 a due to the fragments of the glass plate G scattered from the crushing mechanism 20 is prevented. Can be suppressed.

  According to the glass sheet manufacturing apparatus 1 provided with the glass sheet discarding apparatus 10, for example, at the time of maintenance such as replacement of facilities, the strip-shaped glass sheet G can be smoothly discarded without interruption. .

  At least the transport rolls 5a cover the upper side where the fragments of the glass sheet G are scattered from the crushing mechanism and the side on the side of the crushing mechanism 20 with the protective cover 25, so that the scattered pieces of the glass sheet G are scattered. This can effectively suppress the damage to the transport roll 5a.

  In addition, since the protective cover 25 has the guide surface 29 for guiding the glass plate G fed by the transport device 6 to the upper surface side and guiding the glass plate G to the crushing mechanism 20, the protective cover 25 covers the transport roll 5a. G can be smoothly guided to the crushing mechanism 20 to be crushed.

  Further, the transport roll 5b adjacent to the downstream side of the crushing mechanism 20 can be moved between a normal position where the glass sheet G can be transported and a retracted position deviating from the normal position. Therefore, by moving the transport roll 5b to the retracted position, it is possible to suppress damage caused by the fragments of the glass sheet G scattered from the crushing mechanism 20.
