Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, a glass plate manufacturing apparatus provided with the glass plate disposal apparatus of the present embodiment will be described.
FIG. 1 is a perspective view showing an apparatus for producing a glass sheet.
As shown in fig. 1, a glass sheet manufacturing apparatus 1 provided with the glass sheet discarding apparatus of the present embodiment includes a melting furnace 2, a molten metal bath 3, and a slow cooling furnace 4. The manufacturing apparatus 1 is an apparatus for manufacturing a glass sheet G by a float method. The glass plate discarding apparatus according to the present embodiment is provided downstream of the manufacturing apparatus 1.
In the manufacturing apparatus 1, the glass Gm melted in the melting furnace 2 flows into the molten metal bath 3. Then, in the liquid metal bath 3, the molten glass Gm floats on the molten metal (tin) M in the liquid metal bath 3 and flows to form a smooth glass sheet G. The glass sheet G is conveyed to the annealing furnace 4, annealed, conveyed by a conveyor 6 composed of a plurality of rollers 5, cut into a predetermined size, and sent out.
Fig. 2 is a schematic side view illustrating a glass plate discarding apparatus according to the present embodiment.
As shown in fig. 2, the glass plate discarding apparatus 10 of the present embodiment includes a breaking mechanism 20, a hopper 30, and a scriber 40. The breaking mechanism 20, the hopper 30, and the scriber 40 are provided midway in the conveyor 6 that conveys the belt-like glass sheet G fed from the manufacturing apparatus 1 in the conveying direction a, the hopper 30 is disposed upstream of the breaking mechanism 20, and the scriber 40 is disposed upstream of the hopper 30.
The crushing mechanism 20 includes: a pinch roller 21 composed of a pair of metal rollers that pinch and feed out the glass sheet G from the upper and lower sides; and a hammer roller 22 for rotating and crushing the glass sheet G fed out from the pinch roller 21. In the crushing mechanism 20, the glass sheet G is crushed by the hammer roller 22 into cullet and discarded.
The hopper 30 provided upstream of the crushing mechanism 20 includes a plurality of (five in this example) movable rollers 31. The hopper 30 provided with these movable rollers 31 is inclined downward as a whole with respect to the conveyance direction a of the glass sheet G conveyed from the upstream side by descending the downstream side with the axial center of the movable roller 31 at the upstream end as the center (see the two-dot chain line in fig. 2). This enables the glass sheet G conveyed from the upstream side to be fed obliquely downward. A protective cover 36 is provided below the hopper 30. Thereby, the lower sides of the plurality of movable rollers 31 of the hopper 30 are covered and protected by the protective cover 36.
Fig. 3 is a perspective view showing a crushing unit provided below the hopper.
As shown in fig. 3, a crusher 32 is provided below the delivery end of the hopper 30 for delivering the glass sheets G. The crushing section 32 has a structure in which a plurality of crushing tables 33 are arranged, and each crushing table 33 has a crushing rod 35 that is erected via a leg 34. The glass sheet G fed out from the hopper 30 falls down to the crusher 32. Thereby, the glass sheet G comes into contact with the crushing rod 35 of the crushing table 33 to crush the glass sheet G.
The scriber 40 provided on the upstream side of the hopper 30 includes a scribing wheel 41 that moves in the width direction of the glass sheet G. In the scribe device 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 glass sheet G in a normal operation. In the manufacturing apparatus 1, when maintenance or the like is performed, a glass sheet discarding operation is performed in which the glass sheet discarding apparatus 10 discards a strip-shaped glass sheet G sent from the upstream.
In the glass sheet discarding apparatus 10 of the present embodiment, the first discarding operation and the second discarding operation can be performed. The first discarding operation and the second discarding operation will be described below.
The first discarding operation is performed when a large number of glass sheets G are discarded, which are always sent out, due to a defect in the manufacturing apparatus 1 or the like, and the second discarding operation is performed when glass sheets G are temporarily discarded normally due to normal maintenance or the like.
FIG. 4 is a schematic side view for explaining the operation of the glass plate discarding apparatus. FIG. 5 is a schematic view showing a tilted hopper of the glass plate discarding apparatus.
(first discard run)
In the first disposal operation, the belt-shaped glass sheet G fed from the glass sheet G manufacturing apparatus 1 is crushed by the crushing mechanism 20 and disposed of. Specifically, the crushing mechanism 20 is driven to move the nip rollers 21 in the direction of approaching each other, and rotate in the opposite directions while nipping the glass sheet G. Thereby, the glass sheet G is sent out to the rotating hammer roller 22. Then, the glass sheet G is crushed by the hammer roller 22 to become cullet, which is discarded.
(second discard run)
As shown in fig. 4, in the second discard operation, a band-shaped glass sheet G fed from the glass sheet G manufacturing apparatus 1 is cracked by the scriber 40, and the hopper 30 is driven to be inclined. Then, the glass sheet G fed is cut at the crack formation portion by its own weight and fed downward from the hopper 30. Thereby, the belt-shaped glass sheet G fed from the manufacturing apparatus 1 is cut into a predetermined length and fed out in a direction different from the normal conveyance direction a.
The glass sheet G fed out from the hopper 30 falls down to a crusher 32 provided below the feed end thereof. Thereby, the glass sheet G is crushed by contacting the crushing rod 35 of the crushing table 33. The cullet pieces of the glass sheets G crushed by the crusher 32 are conveyed by a conveyor (not shown) provided below the crusher 32.
As shown in fig. 5, the hopper 30 provided in the glass sheet discarding apparatus 10 of the present embodiment is inclined at an inclination angle θ by rotating about the axial center Oa of the movable roller 31a at the upstream end and lowering the downstream side. The inclination angle θ is an inclination angle of a straight line LA passing through the axial center O of each movable roller 31 when the hopper 30 is inclined while rotating around the axial center Oa of the movable roller 31a at the upstream end. Further, the downstream side of the hopper 30 is lowered by the displacement height H due to the inclination. The displacement height H is a height dimension between a vertical line LB passing through the most downstream end E of the hopper 30 in the horizontal state and an intersection of straight lines LA passing through the axes O of the movable rollers 31 of the hopper 30 in the horizontal state and the inclined state. When the horizontal length from the axial center Oa of the movable roller 31a at the upstream end to the downstream-most end E of the hopper 30 in the horizontal state is L, the horizontal length L, the inclination angle θ, and the displacement height H described above are in the relationship of the following formula (1).
H＝Ltanθ…(1)
In the present embodiment, when the thickness t of the glass sheet G fed from the manufacturing apparatus 1 is 0.1mm to 2.0mm, the inclination angle θ is set so that the relationship Ltan θ (H) between the horizontal length L and the inclination angle θ falls within a range of 100mm to 500 mm.
Here, the inventors of the present invention have studied an optimum inclination angle θ at which the glass sheet G fed out along the hopper 30 is cut off satisfactorily and smoothly at the crack formation portion formed by the scriber 40 by adjusting the inclination angle θ of the hopper 30 when the thickness t of the glass sheet G fed in from the manufacturing apparatus 1 is 0.1mm to 2.0 mm.
When the relation Ltan theta between the horizontal length L of the hopper 30 and the inclination angle theta is smaller than 100mm when the thickness t of the glass sheet G is 0.1mm to 2.0mm, the moment applied to the glass sheet G by the self weight is too small and the glass sheet G is not cut at the crack formation portion, so that the glass sheet G is difficult to discard. When the relationship Ltan θ between the horizontal length L and the inclination angle θ of the hopper 30 is larger than 500mm, the moment applied to the glass sheet G by its own weight is too large, and the glass sheet G scatters around the powder crushed at the crack formation site, and the conveyance roller 5 of the conveyance device 6 or the movable roller 31 of the hopper 30 may be damaged.
As a result, it was found that when the thickness t of the glass sheet G is 0.1mm to 2.0mm, the glass sheet G can be cut satisfactorily and smoothly at the crack formation portion by setting the inclination angle θ so that the relationship Ltan θ between the horizontal length L and the inclination angle θ falls within a range of 100mm to 500 mm. It is found that the relationship Ltan θ between the horizontal length L and the inclination angle θ is more preferably in a range of 114mm to 455 mm.
As described above, in the present embodiment, when the thickness of the glass sheet G is 0.1mm to 2.0mm, the inclination angle θ is set so that the relationship Ltan θ between the horizontal length L and the inclination angle θ falls within a range of 100mm to 500 mm. Further, by feeding the glass sheet G into the inclined hopper 30, an appropriate moment due to its own weight can be applied to the crack formation portion of the glass sheet G. This can suppress scattering of the glass pieces due to cutting, and can smoothly cut and discard the glass sheet G at the crack formation portion.
Further, according to the glass sheet manufacturing apparatus 1 including the glass sheet discarding apparatus 10, the ribbon-shaped glass sheet G can be smoothly discarded without interruption, for example, at the time of maintenance such as replacement of equipment.
Further, a crusher 32 for crushing the glass sheets G fed and in contact with each other is provided below the feeding end of the hopper 30 for feeding the glass sheets G. Therefore, the glass sheets G fed from the hopper 30 can be crushed by the crusher 32 and easily collected.
Further, the hopper 30 is provided with a protective cover 36 for covering the lower side. Thus, even if the glass sheet G fed from the hopper 30 is broken and the glass pieces scatter, the movable roller 31 of the hopper 30 can be protected from the scattered glass pieces by the protective cover 36.
The present invention is not limited to the above-described embodiments, and modifications and applications of the embodiments by combinations of the respective configurations of the embodiments and modifications and applications by those skilled in the art based on the description of the specification and known techniques are also intended to be included in the scope of the present invention.
For example, as shown in fig. 6, the protective cover 37 covering the upper side of the movable roller 31 of the hopper 30 may be detachable. In this case, the protective cover 37 is disposed at a standby position displaced from above the hopper 30 during a normal operation for producing the glass sheets G, and is disposed at a protective position above the hopper 30 during a second discard operation for discarding the glass sheets G while the hopper 30 is tilted. By disposing the protective cover 37 at the protective position, the upper portion of the hopper 30 is covered and protected by the protective cover 37. In this way, by covering the upper side of the hopper 30 during the second disposal operation, even if the glass sheet G breaks and the glass pieces scatter on the movable roller 31 of the hopper 30, the movable roller 31 can be protected from the scattered glass pieces.
In fig. 6, the protective cover 37 is detachably provided on the upper side of the movable rollers 31 other than the movable roller 31a at the upstream end of the hopper 30, but the protective cover 37 may be detachably provided on the upper side of all the movable rollers 31 of the hopper 30.
