Other aspects and advantages of the present invention will become more apparent from the following description, taken in conjunction with the accompanying drawings.

Hereinafter, an embodiment of a manufacturing apparatus for manufacturing a glass ribbon (ribbon glass) as an example of a glass article will be described with reference to the drawings. In addition, in the drawings, for convenience of explanation, a part of the configuration may be exaggerated or simplified. In addition, there are actually different cases regarding the size ratio of each part.

As shown in Fig. 1 (a) and Fig. 1 (b), the glass ribbon manufacturing apparatus 11 includes a molded portion 12 in which a glass ribbon G is formed by a down-draw method. The glass ribbon manufacturing apparatus 11 of the present embodiment is an apparatus for manufacturing a glass ribbon G by an overflow down-draw method using a down-draw method.

As shown in Fig. 1(b), the molded portion 12 of the glass ribbon manufacturing apparatus 11 has a groove 12a for overflowing the molten glass MG, and a first guiding surface 12b and a second guiding surface 12c for use. The molten glass MG that guides the overflow flows down. The second guiding surface 12c is located on the opposite side of the first guiding surface 12b. A part of the molten glass MG is merged or fused at a lower end of the forming portion 12 by a part of the molten glass MG flowing down the first guiding surface 12b and another part of the molten glass MG flowing down the second guiding surface 12c. The shaped glass ribbon G is formed.

The glass ribbon manufacturing apparatus 11 includes at least one roller disposed under the molding portion 12. In the example of FIGS. 1(a) and 1(b), at least one roller may include, for example, one or a plurality of first driving rollers 13 arranged in order from the upstream of the downstream direction Z of the glass ribbon G; one or plural One non-driven roller 14a; one or a plurality of non-driven rollers 14b and one or a plurality of second driving rollers 15. Each roller is typically a cylindrical roller. The downflow direction Z is typically in the vertical direction.

The first driving roller 13 may be a plurality of first driving roller subsets that are disposed apart from each other in the width direction X so as to sandwich both end portions in the width direction X of the glass ribbon G in the thickness direction Y, and the plurality of first driving rollers Each subset of rollers contains at least 2 rollers. In the example of FIG. 1 , the first driving roller 13 includes four rollers arranged to sandwich both end portions of the glass ribbon G in the width direction X. Each of the first driving rollers 13 is driven to rotate by the motor 16. The first driving roller 13 is configured to prevent the glass ribbon G from being contracted inward in the width direction by being brought into contact with both end portions in the width direction X of the glass ribbon G in order to manufacture the glass ribbon G having a predetermined glass width.

The non-driven roller 14a may be a plurality of non-driven roller subsets separated in the width direction X so as to sandwich both end portions of the glass ribbon G in the width direction X in the thickness direction Y, and the plurality of non-driven roller subsets Each contains at least 2 rollers. In the example of FIG. 1, the non-driving roller 14a includes four rollers arranged so as to sandwich both end portions in the width direction X of the glass ribbon G at a position different from the first driving roller 13. Each of the non-driving rollers 14a is different from the first driving roller 13, and is a so-called independent roller that does not impart a rotational driving force from a driving source such as a motor, and that follows the flow of the glass ribbon G passively. The non-driven roller 14a is configured to prevent the glass ribbon G from being contracted inward in the width direction by being brought into contact with both end portions of the glass ribbon G in the width direction X in order to manufacture the glass ribbon G having a predetermined glass width.

Similarly, the non-driven roller 14b may be a plurality of non-driven roller subsets that are disposed apart from each other in the width direction X so as to sandwich both end portions of the glass ribbon G in the width direction X in the thickness direction Y, and the plurality of non-driving rollers Each of the subset of drive rollers contains at least 2 rollers. In the example of FIG. 1, the non-driving roller 14b includes four rollers arranged so as to sandwich both end portions in the width direction X of the glass ribbon G at a position different from the non-driving roller 14a. Each of the non-driving rollers 14b is different from the first driving roller 13, and is a so-called independent roller that does not impart a rotational driving force from a driving source such as a motor, and that follows the flow of the glass ribbon G passively. The non-driven roller 14b is configured to prevent the glass ribbon G from being contracted inward in the width direction by being brought into contact with both end portions of the glass ribbon G in the width direction X in order to manufacture the glass ribbon G having a predetermined glass width.

Further, when the first driving roller 13 and the non-driving rollers 14a and 14b are configured to cool the end portions in the width direction of the glass ribbon G, it is preferable to provide a hollow portion inside the rollers 13, 14a and 14b. And circulating a refrigerant in the hollow portion. In the case where the first drive roller 13 and the non-driving rollers 14a and 14b are configured to cool the end portions in the width direction of the glass ribbon G as described above, it is possible to more appropriately suppress the glass ribbon G from being contracted inward in the width direction.

The second driving roller 15 may be a plurality of second driving roller subsets that are disposed apart from each other in the width direction X so as to sandwich both end portions in the width direction X of the glass ribbon G in the thickness direction Y, and the plurality of second driving rollers Each of the subset of drive rollers contains at least 2 rollers. In the example of FIG. 1 , the second drive roller 15 includes four rollers that are disposed so as to sandwich both end portions in the width direction X of the glass ribbon G at a position different from the first drive roller 13 . Further, in the present embodiment, the second driving roller 15 has two outer rollers and two inner rollers that are connected to each other so as to be rotatable together. The second drive roller 15 is coupled to the motor 18 via the rotary shaft 17 and is rotated by the motor 18. The second driving roller 15 disposed on the downstream side of the first driving roller 13 and the non-driving rollers 14a and 14b is rotated in a state in which both end portions in the width direction X of the glass ribbon G are wrapped to bring the glass ribbon. G is drawn to the down direction Z. Further, the glass ribbon G pulled by the second driving roller 15 is transported to a post-processing such as a cutting process. Usually, the final glass article is produced through a post-process, but the glass ribbon G itself may be the final glass article.

The glass ribbon manufacturing apparatus 11 includes a control unit 20 that controls driving of the motors 16 and 18, a rotation detecting unit 21 that detects rotation information of each of the non-driven rollers 14a, and a notification unit 22.

The rotation detecting portion 21 outputs an output signal in response to the rotation of the non-driving roller 14a to the control portion 20. The control unit 20 calculates, for example, the rotational speed (peripheral velocity) of the non-driven roller 14a based on the output signal from the rotation detecting unit 21. Further, when the calculated rotational speed of the non-driven roller 14a is not within the normal range set in advance, the control unit 20 determines that the rotation of the non-driven roller 14a is abnormal, and outputs an abnormality detection signal to the notifying unit 22. .

The notification unit 22 notifies that the rotation of the non-driven roller 14a is abnormal due to the abnormality detection signal input from the control unit 20. In the present embodiment, the notification unit 22 includes the display 23 and the speaker 24, and is configured to display an alarm sound from the speaker 24 based on the abnormality detection signal, and display warning information indicating that the rotation of the non-driven roller 14a is abnormal. The control unit 20 is communicably connected, for example, via a wired or wireless communication link 28 and a rotation detecting unit 21.

Next, the action of the present embodiment will be described.

The glass ribbon G flowing down from the molding portion 12 has a predetermined glass width secured by the first driving roller 13 and the non-driving rollers 14a and 14b, and is pulled by the second driving roller 15 to the downflow direction Z. At this time, the first drive roller 13 and the second drive roller 15 are rotated by the motors 16 and 18, respectively, and the non-driven rollers 14a and 14b are passively rotated following the flow of the glass ribbon G. Further, the rotational speed (circumferential speed) of the second driving roller 15 that pulls the glass ribbon G is set to be faster than the rotational speed (peripheral speed) of the first driving roller 13, and is located at the first and second driving rollers. The non-driven rollers 14a and 14b between 13 and 15 are preferably rotated at a rotational speed (peripheral speed) equal to or higher than the rotational speed of the first drive roller 13 and equal to or lower than the rotational speed of the second drive roller 15. In the case where the first driving roller 13 and the non-driving rollers 14a and 14b are configured as a cooling roller that cools the end portion in the width direction of the glass ribbon G, the intermediate portion in the width direction of the glass ribbon G is used. The viscosity of the end portion becomes high, and the glass ribbon G can be appropriately suppressed from contracting inward in the width direction.

In this case, the rotation speed of the non-driven roller 14a may be abnormal due to an abnormality of the non-driving roller 14a or other manufacturing equipment (the apparatus including the molding unit 12 and the first and second driving rollers 13 and 15). The rotation speed of the non-driven roller 14a is caused to be faster or slower than the normal range. For example, the non-driving roller 14a is caused when the shape of the glass ribbon G reaching the non-driving roller 14a is abnormal due to some abnormality of the manufacturing device of the upper portion of the non-driving roller 14a, such as the forming portion 12 or the first driving roller 13 or the like. The rotation speed will produce an abnormality. Further, for example, a case where the smooth rotation of the non-driving roller 14a is hindered by the defect of the bearing that pivotally supports the non-driving roller 14a; or the case where the non-driven roller 14a generates the shaft vibration (vibration in the direction orthogonal to the axis) The rotational speed of the non-driven roller 14a causes an abnormality.

When the non-driving roller 14a generates a rotation abnormality, the abnormality 値 is displayed by the rotation speed of the non-driven roller 14a calculated by the control unit 20 based on the output signal from the rotation detecting unit 21, and the control unit 20 outputs the abnormality detection signal to the notification. Part 22. Then, based on the abnormality detection signal, the display 23 of the notification unit 22 and the speaker 24 perform notification of the abnormal rotation of the non-driven roller 14a. In other words, the operator can grasp that the abnormality has occurred in the non-driven roller 14a or other manufacturing equipment (the molding unit 12 and the first and second driving rollers 13, 15 and the like).

Next, the efficacy characteristics of the present embodiment will be described.

(1) The glass ribbon manufacturing apparatus 11 includes a rotation detecting unit 21 that detects rotation of the non-driven roller 14a, and a control unit 20 that based on the rotation information of the non-driven roller 14a detected by the rotation detecting unit 21. The abnormal state of the non-driven roller 14a is detected, and the notifying unit 22 notifies the state of the non-driven roller 14a based on the abnormality detection by the control unit 20. According to this configuration, when the state of the non-driving roller 14a is abnormal, the notification unit 22 notifies the state of the abnormality as a treatment operation, and the operator can quickly grasp that the non-driven roller 14a or another manufacturing device is abnormal. As a result, it is possible to promptly perform the confirmation of the abnormality of the manufacturing equipment including the molding unit 12 and the various rollers 13, 14a, 14b, and 15 and the correspondence with the abnormality.

(2) The rotation detecting unit 21 and the control unit 20 detect an abnormality in the rotational speed of the non-driven roller 14a, and the abnormality of the rotational speed is notified by the notifying unit 22. According to this configuration, the abnormality of the manufacturing equipment and the abnormal shape of the glass ribbon G due to the abnormality are easily reflected in the rotational speed of the non-driven roller 14a. Therefore, the abnormality of the rotational speed of the non-driven roller 14a is performed by the notifying unit 22. It is reported that it can correspond to a large number of abnormalities.

(3) The object of abnormality detection by the rotation detecting unit 21 and the control unit 20 is referred to as a non-driving roller 14a. Since the non-driven roller 14a is passively rotated following the flow of the glass ribbon G, the shape of the glass ribbon G due to abnormality of the apparatus is easily reflected in the rotational speed of the non-driven roller 14a. Therefore, the operator can more appropriately grasp the abnormal shape of the glass ribbon G until the abnormality of the device causing the abnormality.

Further, the above embodiment may be modified as described below.

In the above embodiment, the rotational speed of the non-driven roller 14a among the non-driven rollers 14a and 14b is detected, and an abnormality is detected based on the rotational speed. However, the rotational speed of the non-driven roller 14b or the non-driving is detected. The rotation speed of both of the rollers 14a and 14b may be detected based on the rotation speed.

In addition, although the above-described embodiment is not particularly mentioned, a retracting drive unit 25 (see FIG. 1) such as a fluid pressure cylinder may be provided, and the non-driving roller 14a may be made based on the abnormality detection signal input from the control unit 20. The glass ribbon G is retracted in such a manner that it is separated from the thickness direction Y or the width direction X. In this case, when detecting the abnormality of the rotation of the non-driving roller 14a, the control unit 20 outputs an abnormality detection signal to the notifying unit 22 and the evacuation driving unit 25, and the notification unit 22 performs the notification of the rotation abnormality, and at the same time, the retracting driving unit The driving of 25 causes the non-driven roller 14a to retreat in the thickness direction Y or the width direction X with respect to the glass ribbon G.

According to this configuration, when the rotation abnormality of the non-driving roller 14a is detected, the non-driving roller 14a is separated from the glass ribbon G by the driving of the retracting driving unit 25, so that the non-driving roller 14a that causes the rotation abnormality can be brought to the glass ribbon G. The effect of the suppression is small. For example, in the case where the rotation of the non-driving roller 14a is extremely slow due to a defect of a bearing or the like, the glass ribbon G is scattered due to contact with the non-driving roller 14a, and the scattered glass falls on the apparatus of the rear stage (the second driving roller 15) Or the equipment of the following).

With this configuration, the non-driven roller 14a is retracted from the glass ribbon G by the drive of the retracting drive unit 25 when the rotation abnormality is detected. Therefore, it is possible to prevent the glass ribbon G from scattering due to the non-driven roller 14a that causes the rotation abnormality. In the event, the influence of the rotation abnormality of the non-driven roller 14a can be suppressed to be small. According to this configuration, the non-driven roller 14a automatically retracts according to the abnormality detection, and the retraction of the non-driven roller 14a as the treatment operation can be performed more quickly.

In addition, as described above, the treatment unit that performs the treatment operation based on the abnormality detection signal from the control unit 20 includes both the notification unit 22 and the evacuation drive unit 25. However, the notification unit 22 is not provided and only the evacuation is provided. The drive unit 25 may be configured as a treatment unit.

In the above-described embodiment, the control unit 20 detects the abnormality of the rotation of the non-driven roller 14a based on the rotational speed of the non-driven roller 14a calculated by the output signal of the rotation detecting unit 21, but it is also based on, for example, the rotation detection. The rotation acceleration of the non-driven roller 14a calculated by the output signal of the output unit 21 may detect that the rotation of the non-driven roller 14a is abnormal. Further, it is assumed that the non-driving is detected based on a difference in rotational speed (or a speed ratio) between the first driving roller 13 and the non-driving roller 14a, or a difference in rotational speed (or a speed ratio) between the second driving roller 15 and the non-driving roller 14a. The rotation of the roller 14a may be abnormal. Further, when a plurality of driving rollers are provided, it is preferable to detect the rotation abnormality by comparing the rotational speed of the driving roller closest to the distance between the non-driving rollers 14a and the rotational speed of the non-driven roller 14a. The closer the distance between the rollers is, the closer the rotation speed in normal is, and the easier and more accurate detection of the abnormal state is easier.

Further, in the above-described embodiment, the rotation detecting unit 21 and the control unit 20 detect the abnormality of the rotation of the non-driven roller 14a, and based on the detection of the rotation abnormality, the control unit 20 outputs the abnormality detection signal to the notifying unit 22. However, it is not particularly limited to this. For example, it is assumed that the displacement abnormality of the non-driven roller 14a is detected, and based on the detection of the displacement abnormality, the control unit 20 may output the abnormality detection signal to the notification unit 22.

An example of this is shown in FIG. In the example of FIG. 2, as means for detecting the displacement abnormality of the non-driven roller 14a, an imaging unit 31 including a camera having an imaging element such as a CCD or a CMOS is provided. The imaging unit 31 images a part or all of the non-driven roller 14 a (and the rotating shaft), and outputs the captured image data to the control unit 20 . The control unit 20 calculates the displacement characteristic 非 of the non-driving roller 14a (for example, the position information of the non-driven roller 14a) based on the image data obtained from the imaging unit 31. Then, the control unit 20 determines whether or not the displacement (position) of the non-driven roller 14a is abnormal or not based on the calculated displacement characteristic 値 of the non-driven roller 14a, and determines that the notification unit 22 outputs an abnormality when it is determined that an abnormality has occurred. Check out the signal.

According to this configuration, for example, when the non-driving roller 14a generates the shaft vibration, the abnormality 値 is displayed by the displacement characteristic 値 of the non-driven roller 14a calculated by the control unit 20, and the abnormality detection signal is output from the control unit 20 to the notification. Part 22. Then, based on the abnormality detection signal, the display 23 of the notification unit 22 and the speaker 24 perform notification of the abnormal displacement of the non-driven roller 14a. By the notification by the notification unit 22, the operator can quickly grasp that the non-driven roller 14a is deformed by a shaft vibration or the like without causing a desired glass ribbon G or the like.

In the example shown in FIG. 2, the imaging unit 31 is provided as means for detecting the displacement abnormality of the non-driving roller 14a. However, the imaging unit 31 is not particularly limited thereto, and for example, by a contact displacement sensor or A non-contact displacement sensor such as an optical type can detect an abnormality in the displacement of the non-driven roller 14a (or the rotating shaft).

In the example shown in FIG. 2, the imaging unit 31 detects an abnormality in the displacement of the non-driven roller 14a among the non-driven rollers 14a and 14b, but detects that the displacement of the non-driven roller 14b is abnormal, The configuration of the displacement of both the non-driven rollers 14a and 14b may be abnormal.

Further, for example, as shown in FIG. 3, the temperature sensor 32 built in the non-driving roller 14a detects that the temperature of the non-driven roller 14a is abnormal, and outputs an abnormality detection signal to the notification unit based on the detection of the temperature abnormality. 22 is also possible. Further, in a state where the temperature of the non-driving roller 14a is abnormal, a desired shape or the like in which the glass ribbon G is not formed may occur. In this case, the non-driving roller 14a is particularly remarkable in the case of a cooling roller that cools the end portion of the glass ribbon G in the width direction.

According to this configuration, the temperature of the non-driven roller 14a measured by the temperature sensor 32 is abnormally displayed, and after the abnormality detection signal is output from the control unit 20 to the notification unit 22, the detection signal of the notification unit 22 is detected based on the abnormality detection signal. 23 and the speaker 24 perform notification of the temperature abnormality of the non-driven roller 14a. As a result, the operator can quickly grasp that the temperature of the non-driving roller 14a is abnormal and the desired glass ribbon G is not formed by the notification by the notification unit 22.

When the non-driven roller 14a generates a shaft vibration or a temperature abnormality, the rotational speed of the non-driven roller 14a tends to fluctuate. Therefore, the configuration for detecting the abnormality of the rotational speed as in the above-described embodiment may correspond to the non- The shaft vibration or temperature of the driving roller 14a is abnormal.

Further, in the example shown in FIG. 3, the temperature sensor 32 detects the temperature abnormality of the non-driven roller 14a among the non-driven rollers 14a and 14b, but detects that the temperature of the non-driven roller 14b is abnormal, or The temperature of both of the non-driving rollers 14a and 14b may be abnormal.

In the above-described embodiment, the warning information for causing the speaker 24 to emit an alarm sound based on the abnormality detection signal from the control unit 20 and displaying the abnormality of the rotation of the non-driven roller 14a on the display 23 is displayed on the display 23, but the notification unit 22 The notification aspect to be performed is not limited to this, and for example, it may be configured to be notified by lighting of a warning light.

In the above-described embodiment, the state in which the non-driving roller 14a is abnormal (the rotation abnormality in the above-described embodiment) can be reported by the notifying unit 22, but the first and second driving rollers 13 and 15 are configured, for example. At least one of the state abnormalities (for example, a rotation abnormality) can be notified by the notifying unit 22. In addition, the state of the non-driving roller 14a and the first and second driving rollers 13 and 15 may be notified by the notifying unit 22.

In the above-described embodiment, the first driving roller 13, the non-driving roller 14a, the non-driving roller 14b, and the second driving roller 15 are arranged in the lower portion of the molding portion 12 from the upstream side, but in the forming portion. The configuration of the roller below the 12 is not limited to the above embodiment, and may be appropriately changed depending on the configuration. In addition, in the above-described embodiment, each of the second driving rollers 15 is integrally rotated by one rotation shaft 17 on the front side and the back side of the glass ribbon G. However, for example, each of the second driving rollers 15 is borrowed. It is also possible to rotate the individual rotating shafts in a state of so-called one-sided support.

In the above-described embodiment, the glass article manufacturing apparatus 11 includes the molded portion 12 in which the glass ribbon G is formed by the down-draw method. However, the molded article 12 may be changed to a molded portion in which the glass is formed by flow-down without being limited to the down-draw method.

The molding portion 12 is sometimes referred to as a suspension molding block, and the suspension molding block is configured to form a fluid glass film from the molten glass MG.
