Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
In the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, left, and right" generally means upper, lower, left, and right as illustrated with reference to the accompanying drawings; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to one aspect of the present application, there is provided an apparatus for monitoring a flow rate of molten glass forming a glass ribbon, wherein the apparatus comprises a thickness measuring unit 10 for detecting a thickness of the glass ribbon G, the thickness measuring unit 10 being configured to be operable to detect the thickness of the glass ribbon G at least two locations.
The device can convert the flow of the molten glass by detecting the thickness of different positions of the generated glass ribbon, does not need to cut and damage the glass ribbon, and is suitable for the production of the glass ribbon.
Specifically, the flow rate S (in kg/h) of the molten glass can be calculated according to the following formula:
S＝60ρVbodyVTransport of+ξ。
Where ρ is the density of the glass ribbon (in g/mm)3)，VBodyIs the volume (in mm) of the glass ribbon3)，VTransport ofIs the speed of conveyance of the glass ribbon (in m/min) and ξ is the weight of the gob (constant value in kg). Wherein, VBodyL is the length of the measured ribbon portion (in mm, optionally 1m for example), W is the effective sheet width of the ribbon (in mm) and t is the thickness of the ribbon (in mm), so the above equation can be modified to S60 ρ LWtVTransport of+ξ。
Due to L, W, VTransport ofAnd xi are known parameters, so that S can be obtained only by obtaining the thickness t of the glass ribbon. With the apparatus of the present application, the thickness t of the glass ribbon can be measured and obtained, and thus the flow rate S of the molten glass can be converted.
Preferably, the apparatus may include a calculation unit electrically connected to the thickness measuring unit 10 to calculate the flow rate of the molten glass based on the detection result of the thickness measuring unit 10. The calculation unit may be configured to perform the above conversion so as to continuously monitor the flow rate of the molten glass in real time. Of course, for the case of temporary monitoring, the calculations may also be sampled manually or selectively by the calculation unit to ensure that the current production is satisfactory.
In order to avoid the problem that the single-point measurement may cause excessive thickness deviation, the thickness measuring unit 10 is used for detecting the thicknesses of at least two positions of the glass ribbon G, so that the accuracy problem caused by the single-point measurement accidentally can be avoided by calculating the average thickness.
In addition, to more accurately obtain the average thickness of the glass ribbon G, the at least two locations include a first location and a second location that are connected in a direction parallel to the plane of the glass ribbon G and outside the lengthwise direction of the glass ribbon G. Thus, the thickness of the glass ribbon G can be measured at different positions in a direction other than the longitudinal direction (i.e., the conveying direction) of the glass ribbon G so as to reflect the thickness variation in the width direction of the glass ribbon G.
To obtain measurements at different positions in a direction other than the lengthwise direction of the glass ribbon G, the form of the thickness measuring unit 10 may be set accordingly. For example, the thickness measuring unit 10 may set a plurality of measuring points in the width direction of the glass ribbon G and/or in an oblique direction oblique to the length direction and the width direction to obtain measured values of the respective positions.
In order to obtain as many measurement results as possible, it is preferable that the thickness measuring device includes a first moving mechanism 20 movable in the width direction of the glass ribbon G, and the thickness measuring unit includes a thickness measuring element 11 mounted to the first moving mechanism 20, as shown in fig. 1 and 2. Thus, the thickness measuring unit 11 can be driven by the first moving mechanism 20 to move in the width direction of the glass ribbon G to obtain desired measurement values at various positions in the width direction of the glass ribbon G as needed.
The first moving mechanism 20 may be in any suitable form as long as it can move the thickness measuring device 11 along the width direction of the glass ribbon G. For example, the first moving mechanism 20 may include a slide rail provided in the width direction of the glass ribbon G, a slider slidably engaged with the slide rail, and a driving member for driving the slider, on which the thickness measuring unit 11 is provided.
To avoid measuring damage to the glass ribbon G, the thickness measuring element 11 may be a non-contact sensor.
In addition, to provide more positional measurements, the apparatus includes a second moving mechanism 30 that is movable along the length of the glass ribbon G, and by providing the first moving mechanism 20 or the thickness measuring element 11 on the second moving mechanism 30, the movement of the thickness measuring element 11 along the length of the glass ribbon G can be achieved by the second moving mechanism 30. It will be appreciated that, during the measurement, the glass ribbon G is always moved in the conveying direction, and in order to obtain the thickness of the glass ribbon G in the same width, the first moving mechanism 20 and the second moving mechanism 30 may be operated cooperatively so that the thickness measuring unit 11 is moved in the width direction of the glass ribbon G while following the movement of the glass ribbon G in the length direction, thereby obtaining the thickness of the glass ribbon G in the same width.
Specifically, as shown in fig. 1, the first moving mechanism 20 may be installed on the second moving mechanism 30, and the thickness measuring element 11 is directly installed on the first moving mechanism 20, so that the second moving mechanism 30 may drive the first moving mechanism 20 to move along the length direction, and the first moving mechanism 20 drives the thickness measuring element 11 to move along the width direction, or the second moving mechanism 30 may be installed on the first moving mechanism 20, and the thickness measuring element 11 is installed on the first moving mechanism 20 through the second moving mechanism 30, so that the second moving mechanism 30 drives the thickness measuring element 11 to move along the length direction, and the first moving mechanism 20 drives the second moving mechanism 30 to move along the width direction.
According to another aspect of the present application, a glass ribbon production system is provided, wherein the glass ribbon production system includes the apparatus of the present application that monitors a flow of molten glass forming a glass ribbon.
By detecting the thickness of the produced glass ribbon at different positions, the flow rate of the molten glass can be calculated, and the glass ribbon does not need to be cut and damaged, so that the method is suitable for producing the glass ribbon. In particular, the glass ribbon production system of the present application begins, inter alia, with roll-to-roll packaged glass ribbon production, which may include, in particular, a winding device for winding the glass ribbon.
In addition, it is understood that the glass ribbon is produced by a process in which the glass is solidified from a molten state to a non-molten state, the entire solidification process being carried out as the glass is conveyed (i.e., drawn). Wherein the glass ribbon production system comprises a conveying device 40 for conveying a glass ribbon G, the conveying device 40 has a glass ribbon conveying area M for carrying non-molten glass, and the thickness measuring unit 10 is arranged corresponding to the glass ribbon conveying area M. In other words, by detecting the thickness of the non-molten glass at the glass ribbon delivery zone M, the flow rate of the molten glass upstream of the delivery device 40 can be reflected.
Preferably, the conveyor 40 is configured to horizontally convey the glass ribbon G to ensure that the glass ribbon G is formed with a uniform thickness.
To obtain a stable flow rate of the molten glass, the conveying speed of the glass ribbon may be controlled in accordance with the change in the flow rate. To this end, the glass ribbon production system may include a control device for controlling the conveying speed of the conveying device 40, which is electrically connected to the thickness measuring unit 10. Wherein the control device may be configured to perform corresponding control based on the feedback from the thickness measuring unit 10, for example, when the measurement result of the thickness measuring unit 10 indicates that the flow rate of the molten glass is increased, the conveying speed of the conveying device 40 may be increased in order to stabilize the thickness of the glass ribbon; when the measurement result of the thickness measuring unit 10 shows that the flow rate of the molten glass is decreased, the conveying speed of the conveying device 40 can be decreased in order to stabilize the thickness of the glass ribbon.
Wherein, in order to obtain the flow rate of the molten glass, the control device may include a calculation unit electrically connected to the thickness measuring unit 10 to calculate the flow rate of the molten glass based on the detection result of the thickness measuring unit 10. The calculation unit may be configured to be able to calculate the data by S-60 ρ LWtVTransport ofThe + ξ is converted so that the control device can continuously monitor the flow rate of the molten glass in real time and control the conveying device 40 accordingly.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto. The technical scheme of the utility model in the technical conception scope, can be right carry out multiple simple variant. The present application includes the combination of individual features in any suitable manner. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations. These simple variations and combinations should also be considered as disclosed in the present invention, all falling within the scope of protection of the present invention.
