Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the use of directional terms such as "upper, lower, left, right" generally means upper, lower, left, right as viewed with reference to the accompanying drawings, unless otherwise specified; "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 a glass production apparatus including a marking device 10 for marking a glass ribbon conveyed in a vertical direction to divide an ear and an effective area of the glass ribbon, a breaking device 20 for separating the effective area along a separation line marked by the marking device 10 and deviating the conveyance directions of the effective area and the ear from each other, and a wrapping device 30 for wrapping the effective area.
This application is marked line and is separated ear material G1 and active area G2 to glass ribbon G that carries in the vertical direction to pass through the wrappage device 30 wrappage with active area G2, need not to carry out the ear material separation on the sheet glass like prior art, avoided the quality defect that rocks and lead to because of rocking that leads to from this. Moreover, in the application, the effective area can be divided into the sheet glass by additionally uncoiling after the coiling through the coiling device 30, the divided operation and the coiling can have different production beats, and the mutual influence is avoided.
The glass production equipment is particularly suitable for manufacturing thin plate glass (the thickness is below 0.2 mm), and quality defects caused by the fact that the thin plate glass is easy to shake are avoided. Wherein, through making glass area G carry along vertical direction, can also utilize gravity to make glass area G stable, extend, avoid sheet glass's rocking. To enable the glass ribbon G to be more stably conveyed in the vertical direction, as shown in fig. 1, the glass manufacturing apparatus may include at least two pairs of stabilizing rollers 150 for stably conveying the glass ribbon in the vertical direction. Wherein the pair of two stabilizing rollers 150 are respectively in rolling contact with both side plate surfaces of the glass ribbon G to stabilize the conveying direction and speed of the glass ribbon G. It will be appreciated that the scoring device 10 may be configured to score the portion of the ribbon that passes over the stabilizing rollers 150 to ensure consistent scoring results, with the ribbon G having optimal conveyance stability as it passes over the area of the stabilizing rollers 150.
In the present application, the lobe apparatus 20 may employ various suitable means to separate the ear material G1 and the effective zone G2 and the conveying direction thereof. In the embodiment shown in fig. 1, the splitting device 20 may include at least two pairs of splitting rollers 21, two splitting rollers 21 of each pair of splitting rollers 21 are respectively located on two sides of the plate surface of the effective area, and the position of each pair of splitting rollers 21 defines the direction of the deviation of the effective area from the conveying direction of the ear material. Specifically, as the scored ribbon G passes through the breaking device 20, the active region G2 may separate from the trim G1 and deflect from the trim G1 along a path defined by the position of the breaking roll 21, guided in rolling contact with the breaking roll 21. Wherein the number of pairs of the splitter rollers 21 required can be set as necessary to smoothly guide the separation and deviation of the effective area G2.
In order to facilitate the deviation of the ear material G1 from the transport direction of the active zone G2, the transport direction of the ear material G1 may be left unchanged, i.e., it is transported further in the vertical direction. To this end, the glass production apparatus includes a gob guiding device 40 that continues to guide the gob in a vertical direction. Specifically, the ear guide device 40 may be a pair of guide rollers, which are respectively located on both sides of the plate surface of the ear to be in rolling contact with the ear.
In addition, to accommodate different production requirements, the splitting roller 21 is arranged to be adjustable in position in the horizontal direction relative to the conveying direction of the ear material. Specifically, each pair of the split rollers 20 may be mounted to the frame in the vertical direction (each pair of the split rollers 20 is substantially horizontally opposed), and each split roller 21 may be provided so that the mounting position can be adjusted in the horizontal direction with respect to the frame, so that the position in the horizontal direction can be adjusted according to a desired guide path to deviate the path from the vertical direction, for example, so that the lower split roller 21 is located on the side of the upper split roller 21 (the farther the lower split roller 21 is horizontally deviated by a greater distance). Preferably, at the position where the effective region G2 is separated from the ear material G1, the splitting roller 21 may be disposed so that the angle between the effective region G2 and the conveying direction of the ear material G1 is 1 to 15 ° to stably separate the effective region G2 from the ear material G1. As the effective region G2 moves away from the ear material G1, the splitter roll 21 may be arranged such that the angle of the effective region G2 with respect to the conveying direction of the ear material G1 gradually increases.
In addition, the distance between the breaking device 20 and the scoring device 10 can be set appropriately according to the thickness of the glass ribbon, etc., to stabilize the portion of the glass ribbon G between the scoring and breaking operations and avoid interference between the breaking and scoring operations. For example, the distance between the fragmentation device 20 and the scribing device 10 may be 20cm to 80cm, preferably 30cm to 50 cm.
Wherein, in order to assist the separation operation of the splitting device 20, the ear guiding device 40 is arranged below the splitting device 20 to stabilize the separated ear G1. Further, in order to facilitate recovery of the ear G1, the glass manufacturing apparatus includes an ear recovery device 50 disposed below the ear guide device 40. Specifically, the ear material recovering device 50 may include a collecting container and a crushing unit (for example, may include a driving shaft and a fan blade disposed on the driving shaft to break and crush the ear material by rotating the fan blade) for crushing the ear material G1, and the vibration generated by the crushing unit to the crushing operation of the ear material G1 is prevented from being transmitted upward and affecting the glass ribbon G and the effective area G2 by the ear material guiding device 40.
In addition, in order to facilitate the coordination of the tact time, the glass manufacturing apparatus includes a drawing device 60 disposed between the breaking device 20 and the wrapping device 30 along the conveying direction of the effective zone, so that the portion of the effective zone between the breaking device 20 and the drawing device 60 can be sagged.
The pulling device 60 may be of any suitable form, and may be a pulling roll, for example. The surface of the traction roller can be coated with a layer of flexible material which does not scratch the surface of the glass, but has friction force with the glass with the friction coefficient of 0.3-0.7, and the material can be materials such as fluororubber, PEEK, UPE, polyurethane and the like. By having the active zone with a sagging portion between the breaking device 20 and the pulling device 60 (i.e., the portion of the active zone G2 located in the buffer zone C in fig. 1), the sagging portion can be utilized to coordinate the production cycle upstream and downstream of the pulling device 60. Specifically, the pulling speed of the pulling device 60 (e.g., the speed of the pulling rolls) is the reference for the downstream station drive speed, which can be adjusted to match the ribbon G conveyance speed, or can be accelerated or decelerated to drive the effective area G2 faster or slower in some cases to control the downstream station conveyance speed. For example, when the splitting operation upstream of the drawing device 60 is fast and the wrapping operation downstream is slow, the splitting operation and the wrapping operation can be operated at respective timings without stopping by sagging.
In addition, the transport direction of the effective area G2 can be guided by the drawing device 60 to horizontal transport in order to be finally wrapped by the wrapping device 30 in the case of horizontal transport. Specifically, the sagging effective area G2 can be conveyed horizontally upward past the roll surface of the draft gear 60.
After the effective area G2 is wrapped by the wrapping device 30, it is also possible to open and divide the glass into sheet-like glass as needed, and therefore, the glass manufacturing apparatus may include a first identification device 70 provided between the drawing device 60 and the wrapping device 30 to identify the division position of the effective area. The first marking device 70 may be configured to mark the desired size of the sheet glass, that is, the effective area G2 may be marked intermittently at a distance of a desired size, and after being uncoiled, the sheet glass may be cut according to the mark of the first marking device 70 to obtain the sheet glass of the desired size.
Furthermore, the glass production apparatus may comprise a defect inspection device 80 arranged between the first identification device 70 and the wrapping device 30. The defect inspection device 80 may take a form conventional in the art to inspect the appearance, internal defects, etc. of the effective area G2, among others.
In order to facilitate the removal of the unqualified products during the subsequent cutting into the sheet glass, the glass production equipment comprises a second identification device 90 arranged between the defect detection device 80 and the wrapping device 30 and a control device for controlling the second identification device 90, wherein the defect inspection device 80 is in communication connection with the control device, so that the control device controls the second identification device 90 to perform defect identification on the effective area according to the inspection result of the defect inspection device 80. Therefore, when the defect inspection device 80 inspects that the defect affecting the product quality exists, a signal can be sent to the control device, the control device can control the second identification device 90 to identify the defect on the part of the defect inspected by the defect inspection device 80 according to the signal, and the sheet glass with the defect identification can be removed when being uncoiled. The control device may control the marking timing of the second marking device 90 according to the conveying speed of the effective area G2, the distance between the second marking device 90 and the defect inspection device 80, and the like, so that the defect mark of the second marking device 90 can be located on the portion of the effective area G2 that has the defect and is separated from the same sheet glass after being unwound.
The first identification device 70 and the second identification device 90 may be of the same structure, for example, both are identification machines, to provide two-dimensional codes, bar codes, letters, numbers, shapes, etc. on the effective area G2 to be identified after being unwound.
In addition, in order to control the production quality, the effective area G2 may be subjected to thickness detection, spot inspection, and the like before being wrapped. A thickness measuring device 100 and/or a sampling device 110 are/is arranged between the splitting device 20 and the rolling device 30.
Among them, the thickness measuring device 100 may be provided to be movable in a direction other than the conveying direction of the effective area G2 in the horizontal direction to be able to detect the uniformity of the thickness of the effective area G2 in the width direction. Preferably, the thickness measuring device 100 may be provided to be movable in a horizontal direction in a direction perpendicular to the conveying direction of the effective area G2. Also, the thickness measuring apparatus 100 may take a suitable form and principle to perform the measurement, and may include, for example, an ultrasonic thickness gauge.
To perform a spot check on active area G2, a portion of the continuous ribbon of glass in active area G2 may be cut and spot checked. To this end, the drawing apparatus 100 may include a cross-cutting machine 111 for scribing the drawing part at the effective area G2, a breaking unit 112 (which may include a lift-up cylinder, for example) for breaking the drawing part along a tangent line of the cross-cutting machine 111, and a drawing unit 113 (which may include a robot, for example) for moving the drawing part to the drawing position. Wherein the spot check unit 113 may move the spot check portion to a nearby inspection location or may move the spot check portion to a nearby conveyor (e.g., belt conveyor 160) to transport the spot check portion to a more remote inspection location.
Where cross-cutter 111 may be scored in any suitable manner, for example, a knife wheel may be included to score the glass by pressing in, or cross-cutter 111 may be a non-contact cut, such as a laser cut.
In the sampling inspection, the conveying of the effective area G2 can be stopped so as to move the cross cutting machine 111 transversely for scribing, and the cross cutting machine 111 can be installed on a device capable of moving transversely. Preferably, in the case of using the thickness measuring device 100, the cross-cutting machine 111 and the thickness measuring device 100 may be mounted on a moving device capable of moving in a horizontal direction in a direction perpendicular to the conveying direction of the effective area G2, and the moving device may be in various suitable forms, such as a belt conveyor, and may be of a non-contact type moving type such as air flotation or ultrasonic levitation.
It will be appreciated that the cutting by the cross-cutting machine 111 and the severing unit 112 can also be performed when it is necessary to divide the active area G2 to cut a length of a bale.
Furthermore, the glass production apparatus comprises a conveying device 120 for conveying the active zone between the breaking device 20 and the wrapping device 30. In particular, the conveying direction of the effective area G2 may be directed to the horizontal direction after passing through the drawing device 60, and the conveying device 120 may be of a type capable of horizontal conveyance. In order to convey the thin glass sheet and avoid shaking of the thin glass sheet, the conveying device 120 may be of a non-contact type, such as air flotation or ultrasonic levitation.
Further, to ensure the surface cleaning of the effective area G, the glass production apparatus includes a dry type cleaning machine 130 that cleans the effective area before being wound by the winding device 30. The dry cleaning machine 130 may perform adhesion cleaning on the effective region G by using a structure and a manner of pressing the glass with rollers. Of course, dry cleaning may be performed in other manners, for example, a blower and an induced draft fan may be provided to suck off the blown-off dirt while blowing off the dirt on the glass. For another example, the dry cleaner 130 may be configured to be capable of being washed by ultrasonic vibration.
In order to protect the glass surface, the glass production apparatus includes a film coating machine 140 that coats the cleaned effective region. Through carrying out the tectorial membrane immediately after the washing, can protect the glass surface on the one hand, on the other hand also can reduce the bend radius when rolling up the package, make the active area more stable in the coiling process, difficult broken.
According to another aspect of the present application, there is provided a glass production method, wherein the glass production method comprises: scoring a glass ribbon conveyed in a vertical direction to divide a cull and an active area of the glass ribbon; separating the active area along the scribed separation line and offsetting the active area and the direction of conveyance of the ear material from each other; and wrapping the effective area.
In the method of the present application, the glass ribbon G conveyed in the vertical direction is scribed and the cullet G1 and the effective area G2 are separated, and the effective area G2 is wrapped by the wrapping device 30, without performing cullet separation on the sheet glass as in the prior art, thereby avoiding the shaking caused thereby and the quality defect caused by the shaking. Moreover, in the application, the effective area can be divided into the sheet glass by additionally uncoiling after the coiling through the coiling device 30, the divided operation and the coiling can have different production beats, and the mutual influence is avoided.
In order to facilitate the coordination of the production cycle, in the method of the present application, after the effective area deviates from the conveying direction of the ear material, the effective area can be pulled and wrapped after undergoing sagging. By subjecting the active area to sag, the portion of the sag can be used to coordinate the production cycle upstream and downstream of the pulling location. For example, when the splitting operation upstream of the drawing position is fast and the wrapping operation downstream is slow, the splitting operation and the wrapping operation can be operated at respective timings without stopping by sagging.
The methods of the present application can be carried out using a variety of suitable equipment, for example, the glass production methods can be carried out using the glass production equipment of the present application.
The following describes the glass production method using the glass production apparatus of the present application with reference to the drawings.
Wherein the glass production apparatus further comprises an overflow device 170 and a stabilizing device 180. The glass ribbon G overflowing from the overflow device 170 is conveyed in the vertical direction at a set speed after being stabilized by a stabilizing device 180 (e.g., including a plurality of pairs of guide rollers, i.e., a plurality of pairs of guide rollers corresponding to the quality adjusting zone B in fig. 1). While being stabilized by the stabilizing rollers 150, the glass ribbon G is scored by the scoring device 10 to distinguish between the ear G1 and the active zone G2.
Subsequently, the ear material G1 and the effective region G2 are separated by the breaking device 20 and the effective region G2 is conveyed away from the vertical direction, and then drawn by the drawing device 60 to form a sag and guide the conveying direction of the effective region G2 to the horizontal direction. The active region G2 is then conveyed horizontally by the conveyor 120 such that the active region G2 passes sequentially through the first identifier 70, the defect inspection device 80, and the second identifier 90 for sheet marking (i.e., for subsequent sheet glass separation upon unwinding), defect inspection, and defect identification, respectively.
Under normal production conditions, the effective region G2 passing through the second identifier 90 can be cleaned by the dry cleaner 130 and immediately coated by the laminator 140, and then can be wrapped by the wrapping device 30, wherein the effective region G2 of a desired length can be cut by the cross-cutting machine 111 and the breaking unit 112 to form a wrapped package of a desired length.
In the case where quality inspection is required, the effective area G2 may also be subjected to thickness measurement and spot inspection by the thickness measuring device 100 and the spot inspection device 110 upstream of the second identification device 90. At the time of sampling, a transverse scribing may be performed in the effective area G2 by the transverse cutter 111, and then a portion to be sampled is broken by the breaking unit 112 to move the sampling portion to the sampling position by the sampling unit 113.
