In the above-described manufacturing apparatus, the sheet glass after passing through the inspection process is conveyed by a roller-type conveying apparatus provided with a plurality of conveying rollers, and then the plurality of sheet glass are collectively bundled by, for example, a bundling apparatus.

Here, the drive transmission mechanism for transmitting the driving force to the conveying rollers of the roller conveying device is generally constituted by a pair of gears that mesh with each other.

However, in the drive transmission mechanism having such a structure, dust generated by abrasion is likely to be generated between the gears, and the plate glass after the cleaning step is again attached with dust, which is an important factor causing deterioration in quality of the plate-like member.

SUMMERY OF THE UTILITY MODEL

Problem to be solved by utility model

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a manufacturing apparatus for a plate-like member, which can sufficiently suppress dust generated from a driving mechanism in a conveying apparatus for conveying a plate-like member having completed a cleaning process.

Means for solving the problems

The present invention addresses the above-described problem, and a solution to this problem will be described below.

That is, the present invention relates to a manufacturing apparatus for a plate-shaped member, including: a floating type conveying device which conveys the cleaned plate-shaped member in a state of floating in a horizontal posture; an inspection device that inspects the quality of the plate-like member conveyed by the floating conveyor; and a roller conveying device which is provided on a downstream side in a conveying direction of the floating conveying device and conveys the plate-shaped member having passed through the inspection device in a state of being placed on the conveying rollers, wherein the roller conveying device includes: a plurality of first conveying rollers for conveying the plate-like member; a first drive motor as a power source; and a first drive transmission mechanism for transmitting a driving force of the first drive motor to the plurality of first conveyance rollers, the first drive transmission mechanism including: a plurality of first drive-side magnetic gears that are rotationally driven by a drive force of the first drive motor; and a plurality of first driven-side magnetic gears that are provided to the plurality of first conveyance rollers, respectively, that are close to the first driving-side magnetic gears, and that are rotationally driven by magnetic force of the first driving-side magnetic gears. Here, the "horizontal posture" of the present invention includes not only a completely horizontal state but also a posture in which the plate-shaped member is conveyed in a state inclined by 1 to 10 ° in order to smoothly flow the washing water from the plate-shaped member in the washing step.

In this way, in the roller type conveying device that conveys the plate-like member having completed the cleaning process, since the first drive-side magnetic gear and the first driven-side magnetic gear that constitute the first drive transmission mechanism are not in contact with each other, dust generated by abrasion is less likely to be generated between the first drive-side magnetic gear and the first driven-side magnetic gear, and it is possible to suppress the occurrence of deterioration in quality of the plate-like member due to the dust re-adhering to the plate-like member after the inspection.

In the apparatus for manufacturing a plate-like member according to the present invention, it is preferable that the floating type carrying apparatus includes: a plurality of support rollers that support an end portion of a lower surface of the plate-like member in a direction orthogonal to a conveying direction; a second drive motor as a power source; and a second drive transmission mechanism for transmitting a driving force of the second drive motor to the plurality of support rollers, the second drive transmission mechanism including: a plurality of second driving-side magnetic gears that are rotationally driven by a driving force of the second driving motor; and a plurality of second driven-side magnetic gears that are provided to the plurality of support rollers, respectively, are close to the second driving-side magnetic gears, and are rotationally driven by magnetic force of the second driving-side magnetic gears.

In this way, in the floating type conveying device that conveys the plate-shaped member at the time of quality inspection by the inspection device, the second driving-side magnetic gear and the second driven-side magnetic gear that constitute the second drive transmission mechanism are in a non-contact state, and therefore, dust due to abrasion is less likely to be generated between the second driving-side magnetic gear and the second driven-side magnetic gear, and it is possible to suppress dust from adhering to the plate-shaped member after the cleaning process and increasing the fraction defective of the plate-shaped member.

In the manufacturing apparatus for a plate-shaped member according to the present invention, it is preferable that the first driving-side magnetic gear is penetrated by a first intermediate shaft, and the first driving motor and the first intermediate shaft are drivingly coupled to each other via a first timing belt.

In this way, by driving and coupling the first drive motor and the first intermediate shaft to each other via the first timing belt, the first drive motor can be disposed at a position separated from the first intermediate shaft and the plurality of first conveying rollers located near the first intermediate shaft.

Therefore, in the case where a chamber or the like surrounding the roller conveyor is provided in order to prevent dust or the like floating around from adhering to the plate-shaped member having completed the cleaning step, for example, the first drive motor can be disposed outside the chamber, and the dust generated by the first drive motor can be prevented from adhering to the plate-shaped member after the inspection again and causing deterioration in quality of the plate-shaped member.

In the apparatus for manufacturing a plate-shaped member according to the present invention, it is preferable that the second driving-side magnetic gear is penetrated by a second intermediate shaft, and the second driving motor and the second intermediate shaft are drivingly coupled to each other via a second timing belt.

In this way, by driving and coupling the second drive motor and the second intermediate shaft to each other via the second timing belt, the second drive motor can be disposed at a position separated from the second intermediate shaft and the plurality of support rollers located near the second intermediate shaft.

Therefore, when a chamber or the like surrounding the floating conveyor is provided in order to prevent dust or the like floating around from adhering to the cleaned plate-like member, the second drive motor can be disposed outside the chamber, and dust generated by the second drive motor (more specifically, dust generated between the drive pulley provided through the output shaft and the second timing belt) can be prevented from adhering to the cleaned plate-like member again and causing deterioration in quality of the plate-like member.

In the manufacturing apparatus for a plate-shaped member according to the present invention, it is preferable that the roller conveyor further includes a first cover member surrounding the first drive transmission mechanism.

With this configuration, the first cover member prevents dust floating around the first drive transmission mechanism from entering the gap between the first drive-side magnetic gear and the first driven-side magnetic gear, and the first drive transmission mechanism can more reliably transmit the driving force.

In the apparatus for manufacturing a plate-like member according to the present invention, it is preferable that the floating conveyance device further includes a second cover member surrounding the second drive transmission mechanism.

With this configuration, the second cover member prevents dust floating around the second drive transmission mechanism from entering the gap between the second drive-side magnetic gear and the second driven-side magnetic gear, and the second drive transmission mechanism can more reliably transmit the driving force.

In the apparatus for manufacturing a plate-shaped member according to the present invention, it is preferable that the apparatus for manufacturing a plate-shaped member further includes, on an upstream side in a conveying direction of the floating conveyor: a cleaning device for cleaning a plate-like member processed into a predetermined outer shape; a drying device for drying the plate-like member cleaned by the cleaning device; and a cleaning roller-type conveying device which conveys the plate-shaped member to the drying device in a state of being placed on the conveying rollers while the plate-shaped member is cleaned by the cleaning device, the cleaning roller-type conveying device comprising: a plurality of third conveying rollers for conveying the plate-like member; a third drive motor as a power source; and a third drive transmission mechanism for transmitting a driving force of the third drive motor to the plurality of third conveyance rollers, the third drive transmission mechanism including: a plurality of driving side gears that are rotationally driven by a driving force of the third driving motor; a plurality of driven side gears provided to the plurality of third conveyance rollers, respectively, and engaged with the driving side gear; and a spraying device for spraying water to the driving side gear and the driven side gear.

With such a configuration, even if dust generated by abrasion is generated between the driving side gear and the driven side gear, the dust can be washed away by the sprayed water, and the adhesion of the dust to the plate-shaped member being cleaned and the increase in the defective fraction of the plate-shaped member can be suppressed.

Effect of the utility model

As an effect of the present invention, the following effects are exhibited.

That is, according to the apparatus for manufacturing a plate-shaped member of the present invention, it is possible to sufficiently suppress dust generated from the driving mechanism in the conveying apparatus that conveys the plate-shaped member having completed the cleaning process.

[ Overall Structure of apparatus 1 for producing sheet glass G ]

First, the overall configuration of a manufacturing apparatus 1 for sheet glass G (hereinafter, briefly referred to as "manufacturing apparatus 1") according to the present invention will be described with reference to fig. 1.

The manufacturing apparatus 1 of the present embodiment is an apparatus for manufacturing a sheet glass G (glass raw material G1) as an example of a plate-shaped member, and manufactures a sheet glass G as a final product by processing a plate-shaped glass raw material G1, which is prepared in advance by an overflow down-draw method or a float method, into a predetermined outer shape, for example.

The plate glass G produced by the production apparatus 1 is a plate glass for a liquid crystal display, but is not limited thereto, and may be a plate glass for other FPD such as a plasma display, an organic EL display, and the like.

The plate-like member is not limited to plate glass, and may be a plate-like member made of metal or resin, for example.

The manufacturing apparatus 1 mainly includes a loading unit 10, an end face processing unit 20, a cleaning unit 30, a drying unit 40, an inspection unit 50, a packing unit 60, and the like, which are sequentially arranged in the conveying direction (the direction of arrow a in fig. 1) of the sheet glass G.

The charging section 10 is a region where the charging step S01 of charging the glass raw material G1 prepared in advance in the previous step into the manufacturing apparatus 1 is performed.

The input unit 10 includes, for example: a rack 10A that temporarily holds a plurality of glass raw materials G1 and G1 in a state where the plurality of glass raw materials G1 and G1 are placed; and a transfer device (not shown) that transfers the plurality of glass raw materials G1, G1 … held by the rack 10A to a processing conveyance device 20A described later.

Then, the plurality of glass raw materials G1, G1 … placed on the rack 10A are sequentially transferred one by one to the upstream portion in the conveying direction of the processing conveyor 20A by the transfer device.

Thus, a plurality of glass materials G1 and G1 … prepared in advance are sequentially charged into the manufacturing apparatus 1.

The end face processing unit 20 is a region where the end face processing step S02 is performed, and in the end face processing step S02, the glass material G1 charged in the charging step S01 is subjected to end face processing to form the glass material G1 into a predetermined outer shape.

The end surface processing portion 20 includes, for example: a processing conveyance device 20A that conveys the glass material G1 in a horizontal posture in one direction (the direction of arrow a in fig. 1); a plurality of cylindrical end face processing grindstones (not shown) arranged in a row along the conveying direction on both sides in the width direction (both sides in the direction orthogonal to the conveying direction (the direction of arrow a) in plan view) of the glass raw material G1 in the processing conveying device 20A; and a processing chamber 20B for covering the periphery of the processing conveyor 20A together with the end face processing grindstones.

Then, the glass raw material G1 transferred to the processing conveyor 20A through the input unit 10 is subsequently conveyed by the processing conveyor 20A toward the cleaning unit 30 described later, and while the end faces on both sides in the width direction of the glass raw material G1 are brought into contact with the outer peripheral surface of the end face processing grindstone to be end-processed, the glass raw material G1 is formed into a predetermined outer shape.

The cleaning unit 30 cleans the glass material G1 whose end surface has been processed in the end surface processing step S0, and is a region where the cleaning step S03 is performed to remove glass frit and the like adhering to the glass material G1.

The cleaning unit 30 includes, for example, a cleaning conveyance device 30A disposed downstream in the conveyance direction of the processing conveyance device 20A and conveying the glass material G1 in a horizontal posture in one direction (the direction of arrow a in fig. 1); a cleaning device 30B disposed above the cleaning conveyance device 30A; and a cleaning chamber 30C that covers the periphery covered by the cleaning conveyance device 30A and the cleaning device 30B.

Here, the cleaning conveyance device 30A is an example of a cleaning roller conveyance device that conveys the glass material G1 in a state of being placed on a conveyance roller (i.e., a third conveyance roller 31 described later), and conveys the glass member G1 toward a drying device 40B of a drying section 40 described later.

The details of the structure of the cleaning conveyance device 30A will be described later.

The cleaning device 30B includes a plurality of brushes 30B1, 30B1 … arranged from the upstream portion to the downstream portion in the conveying direction of the cleaning conveying device 30A, a cleaning liquid jetting nozzle (not shown) for jetting a cleaning liquid to the upper surface of the conveyed glass raw material G1, and the like.

Each brush 30B1 is provided so as to be rotatable about an axial center in a vertical direction, i.e., a direction perpendicular to the upper surface of the conveyed glass raw material G1.

Then, the glass raw material G1 end-finished in the predetermined outer shape in the end face machining step S02 is subsequently conveyed toward the drying unit 40 by the cleaning conveyance device 30A, and the cleaning liquid is ejected from the cleaning liquid ejection nozzles, and the plurality of brushes 30B1 and 30B1 … are rotated and brought into contact with the upper surface of the glass raw material G1.

In this way, the glass frit generated during the end face processing of the glass raw material G1 in the previous step (end face processing step S02) and adhering to the upper surface of the glass raw material G1 is removed, and the glass raw material G1 is cleaned by the cleaning device 30B.

In other words, while the glass material G1 is cleaned by the cleaning device 30B, the glass material G1 is conveyed toward the drying unit 40 by the cleaning conveying device 30A.

The drying section 40 is a region where the drying step S04 is performed, and in the drying step S04, the glass raw material G1 cleaned in the cleaning step S03 is dried to remove water droplets and the like remaining in the glass raw material G1.

The drying unit 40 includes, for example: a drying conveyor device 40A which is disposed downstream in the conveying direction of the cleaning conveyor device 30A and conveys the glass material G1 in a horizontal posture in one direction (the direction of arrow a in fig. 1); a drying device 40B which is disposed at the center in the conveying direction of the drying conveying device 40A and dries the glass material G1 cleaned by the cleaning device 30B; and a drying chamber 40C that covers the drying conveyor 40A and the drying device 40B.

The drying device 40B is configured by, for example, an air knife 40B1 or the like, and the air knife B1 blows compressed air toward the upper surface and the lower surface of the glass raw material G1 conveyed by the drying conveyor 40A.

Then, the glass raw material G1 cleaned in the cleaning step S03 is subsequently conveyed toward the inspection unit 50 described later by the drying conveyor 40A, and compressed air is blown by the air knife 40B 1.

Thus, after the completion of the cleaning of the glass material G1 in the preceding step (cleaning step S03), droplets of a cleaning liquid containing glass frit or the like adhering to the glass material G1 are blown off by compressed air and removed, and the glass material G1 is dried to form a plate glass G as a final product.

The inspection unit 50 is a region where the inspection step S05 of inspecting the quality of the finished sheet glass G dried in the drying step S04 is performed.

The inspection unit 50 includes, for example: an inspection conveying device 50A which is disposed on the downstream side in the conveying direction of the drying conveying device 40A and conveys the sheet glass G in a horizontal posture in one direction (the direction of arrow a in fig. 1); and an inspection device 50B which is disposed at the center in the conveying direction of the inspection conveying device 50A and performs quality inspection of the sheet glass G conveyed by the inspection conveying device 50A.

Here, the inspection conveying device 50A is an example of a floating type conveying device that conveys the plate glass G in a state of floating by compressed air ejected from below, and conveys the plate glass G toward a packing unit 60 described later.

The structure of the inspection conveyance device 50A will be described in detail later.

Further, the inspection apparatus 50B includes, for example: a light projecting mechanism (not shown) for projecting light to the conveyed plate glass G; an imaging mechanism (not shown) for imaging the plane of the plate glass G irradiated by the light projecting mechanism; and a control means (not shown) for analyzing the image data captured by the imaging means and determining whether or not there is a defect in the sheet glass G.

Then, the cleaned plate glass G dried in the drying step S04 is subsequently conveyed by the inspection conveying device 50A toward the package unit 60, which will be described later, and passes through the inspection device 50B in the middle.

When the inspection device 50B passes, the light projection means projects light onto the plane of the plate glass G, and the image pickup means picks up image data of the area irradiated with light on the plane.

The image data captured by the imaging means is sent to the control means and then subjected to arithmetic processing, and the plate glass G is judged for the presence or absence of defects caused by, for example, glass particles, cracks, foreign matter, bubbles, contamination, processing defects, and the like.

In this way, the sheet glass G dried in the previous step (drying step S04) and finished as a final product is subjected to a quality inspection.

As a result of the quality inspection by the inspection device 50B, the sheet glass G determined to be defective after the presence of the defect is confirmed is then taken out from the inspection conveying device 50A, and only the sheet glass G determined to be non-defective after the presence of the defect is not substantially confirmed is conveyed to the bundling unit 60. Further, the present invention is not limited to this embodiment, and the sheet glass G determined to be defective products may be conveyed to the packing unit 60 without being taken out in the middle, and the defective products may be taken out and separated from the products to be packed when packing the packages.

The bundling unit 60 performs a bundling process S06 of bundling a plurality of sheet glasses G, which are final products of which the quality has been inspected in the inspection process S05.

The bundle pack unit 60 includes, for example: a bundle conveying device 60A which is provided on the downstream side in the conveying direction of the inspection conveying device 50A and conveys the plate glass G in a horizontal posture in one direction (the direction of arrow a in fig. 1); and a bundling device (not shown) which is disposed on the downstream side in the conveying direction of the bundling conveying device 60A and bundles a plurality of sheet glasses G and G … collectively.

Here, the conveying device 60A for a bundle is an example of a roller conveying device that conveys the sheet glass G having passed through the conveying device 50A for inspection in a state of being placed on a conveying roller (i.e., the first conveying roller 61), and conveys the sheet glass G toward the bundle packaging device.

The details of the structure of the bundle conveying device 60A will be described later.

Then, the sheet glass G having been subjected to the quality inspection in the inspection step S05 is subsequently conveyed by the packing conveying device 60A, reaches a downstream portion in the conveying direction of the packing conveying device 60A, and is taken out from the packing conveying device 60A by the packing device and is bundled.

As described above, in the manufacturing apparatus 1 of the present embodiment, the sheet glass G as a final product is manufactured by sequentially passing the glass raw material G1 prepared in advance through the input unit 10, the end face processing unit 20, the cleaning unit 30, the drying unit 40, the inspection unit 50, and the packing unit 60.

[ Structure of conveying device for packages 60A ]

Next, the configuration of the bundle conveying device 60A will be described in detail with reference to fig. 2, 4, and 5.

As described above, the packing conveyance device 60A is an example of a roller conveyance device that conveys the sheet glass G in a state of being placed on the conveyance rollers (first conveyance rollers 61), and as shown in fig. 2, the packing conveyance device 60A mainly includes the plurality of first conveyance rollers 61 and 61 … that convey the sheet glass G, the first drive motor 62 as a power source, the first drive transmission mechanism 63 that transmits the driving force of the first drive motor 62 to the plurality of first conveyance rollers 61 and 61 …, and the like.

The first conveyance roller 61 includes a roller shaft 61a extending in the horizontal direction, and a plurality of disk bodies 61b, 61b … and the like provided coaxially with the roller shaft 61a and penetrating at equal intervals in the axial direction.

The first conveying rollers 61 and 61 … are provided in plural and arranged in the conveying direction of the sheet glass G (the direction of arrow a in fig. 2).

Here, the first conveying rollers 61 and 61 … are provided with a first drive transmission mechanism 63 (described later) at one end (left side in the conveying direction of the sheet glass G in the present embodiment), and each first conveying roller 61 is coupled to the first drive motor 62 via the first drive transmission mechanism 63.

Then, the driving force of the first drive motor 62 is transmitted through the first drive transmission mechanism 63, whereby the plurality of first conveyance rollers 61, 61 … are simultaneously rotationally driven in the same direction, and the sheet glass G is conveyed in the conveyance direction (the direction of arrow a) while being placed on the plurality of disc bodies 61b, 61b ….

A rubber or resin annular cushion member (not shown) is attached to the outer peripheral portions of the plurality of disk bodies 61b, 61b …, and conveyance fluctuation and deviation of the stop position of the sheet glass G are prevented.

The first drive motor 62 is disposed in the vicinity of the first drive transmission mechanism 63.

A drive-side pulley 62b is inserted through the output shaft 62a of the first drive motor 62 so as to be positioned coaxially therewith, and the first drive motor 62 is drivingly coupled to a first intermediate shaft 64 of the first drive transmission mechanism 63 via the drive-side pulley 62b, as will be described later.

As shown in fig. 4 (a), the first drive transmission mechanism 63 includes a first intermediate shaft 64, a first drive-side magnetic gear 65, a first driven-side magnetic gear 66, a first timing belt 67, and the like.

The first intermediate shaft 64 is disposed at one end (left end) of the first conveying rollers 61 and 61 … so as to be orthogonal to the first conveying rollers 61 and 61 … in a plan view, and so as to be positioned below the first conveying rollers 61 and 61 … in a front view (see fig. 4 (b)). The first intermediate shaft 64 is not limited to this embodiment, and may be disposed above the first conveying rollers 61 and 61 …, respectively.

The first intermediate shaft 64 is supported rotatably about the axial center by a plurality of first bearings 64a and 64a … that are inserted so as to be positioned on the same axis at least at both end portions.

A driven pulley 64b is inserted through an end portion of the first intermediate shaft 64 on one end side (downstream side in the conveying direction in the embodiment) so as to be positioned coaxially therewith, and a first timing belt 67 is wound between the driven pulley 64b and the driving pulley 62 b.

That is, the first drive motor 62 and the first intermediate shaft 64 are drivingly coupled via the first timing belt 67.

The driving force of the first drive motor 62 is transmitted to the drive-side pulley 62b, the first timing belt 67, and the driven-side pulley 64b in this order, and the first intermediate shaft 64 is rotationally driven around the axial center.

By configuring to drive and couple the first drive motor 62 and the first intermediate shaft to each other via the first timing belt 67 in this way, the first drive motor 62 can be disposed at a position separated from the first intermediate shaft 64 and the plurality of first conveying rollers 61 and 61 … located near the first intermediate shaft 64.

Therefore, when a room or the like surrounding the bundle conveying device 60A is provided, for example, to prevent dust floating around from adhering to the cleaned sheet glass G, the first drive motor 62 can be disposed outside the room, and dust generated by the first drive motor 62 (more specifically, dust generated between the first timing belt 67 and the drive-side pulley 62b provided so as to be penetrated by the output shaft 62 a) can be prevented from adhering to the cleaned sheet glass G again, and the quality of the sheet glass G can be prevented from deteriorating.

However, a plurality of first driving-side magnetic gears 65 and 65 … are inserted through the first intermediate shaft 64 so as to be positioned on the same axis, and the plurality of first driving-side magnetic gears 65 and 65 … are disposed at positions corresponding to the arrangement of the plurality of first conveying rollers 61 and 61 …, respectively.

On the other hand, the first driven-side magnetic gears 66 and 66 … are respectively inserted into one end (end on the first intermediate shaft 64 side) of the first conveying rollers 61 and 61 ….

The first driven-side magnetic gears 66 and 66 … provided in the first conveying rollers 61 and 61 … approach the plurality of first driving-side magnetic gears 65 and 65 … in a state of being orthogonal to the plurality of first driving-side magnetic gears 65 and 65 … of the first intermediate shaft 64 in a plan view (that is, are disposed in a state of not being in contact with the first driving-side magnetic gears 65 and 65 …).

Here, as shown in fig. 5, the first driving-side magnetic gear 65 and the first driven-side magnetic gear 66 are formed in a cylindrical shape, and the magnetic gear 6 is formed on the outer peripheral surface thereof, and the magnetic gear 6 is formed of a permanent magnet in which the N pole 6a and the S pole 6b are alternately spirally magnetized.

In the first drive transmission mechanism 63 configured as described above, as shown in fig. 4 (a), when the driving force of the first drive motor 62 is transmitted to the first intermediate shaft 64 and the plurality of first drive-side magnetic gears 65 and 65 … are rotationally driven together with the first intermediate shaft 64, the plurality of first driven-side magnetic gears 66 and 66 … are also rotationally driven by the magnetic force of the first drive-side magnetic gears 65 and 65 ….

As a result, the plurality of first conveyance rollers 61 and 61 … through which the first driven-side magnetic gears 66 and 66 … are respectively provided are simultaneously driven to rotate in the same direction together with the first driven-side magnetic gears 66 and 66 ….

As described above, in the manufacturing apparatus 1 (see fig. 1) of the present embodiment, since the first driving-side magnetic gear 65 and the first driven-side magnetic gear 66 constituting the first drive transmission mechanism 63 in the packing conveying apparatus 60A that conveys the quality inspection sheet glass G by the inspection apparatus 50B are in a non-contact state, dust generated by abrasion is less likely to be generated between the first driving-side magnetic gear 65 and the first driven-side magnetic gear 66, and it is possible to suppress dust from adhering to the cleaned sheet glass G again and causing deterioration in quality of the sheet glass G.

The bundle conveying device 60A of the present embodiment further includes a first cover member 68 that partially surrounds the periphery of the first drive transmission mechanism 63.

Specifically, the first cover member 68 is formed of, for example, a box-shaped member having a rectangular parallelepiped shape, and is arranged to collectively surround one end portion (end portion on the first intermediate shaft 64 side) of the plurality of first conveying rollers 61 and 61 ….

As a result, the plurality of first driving-side magnetic gears 65 and 65 … and the first driven-side magnetic gears 66 and 66 … that are close to each other are collectively provided in the first cover member 68.

[ Structure of the inspection conveyance device 50A ]

Next, the configuration of the inspection conveyance device 50A will be described in detail with reference to fig. 3.

As described above, the inspection conveyance device 50A is an example of a floating conveyance device that conveys the sheet glass G in a floating state, and the inspection conveyance device 50A mainly includes the floating device 50A1 that floats the conveyed sheet glass G, the first inspection conveyance device 50A2 located on the left side as viewed in the conveyance direction (the direction of the arrow a in fig. 3) of the floating device 50A1, and the second inspection conveyance device 50A3 located on the right side as viewed in the conveyance direction.

Here, since the first inspection conveyance device 50a2 and the second inspection conveyance device 50A3 of the present embodiment are configured to have substantially the same configuration, the first inspection conveyance device 50a2 will be mainly described in the following description, and the second inspection conveyance device 50A3 will not be described.

The floating device 50a1 is configured by a rectangular plate-shaped member having a hollow inside, and is configured by a plurality of (for example, two in the present embodiment) floating plates 51, 51 arranged horizontally, and a discharge pump (not shown) communicating with the floating plates 51, 51 via a piping member.

Further, a plurality of minute discharge holes 51a and 51a … are provided in the upper surface of each floating plate 51.

The compressed air discharged by the discharge pump is sent to the inside of each of the floating plates 51, 51 through a pipe member, and then discharged upward through the discharge holes 51a, 51a ….

Thereby, the lower surface of the sheet glass G is lifted by the compressed air and conveyed in a floating state.

The first inspection conveying device 50A2 has substantially the same configuration as the aforementioned bundle conveying device 60A, and mainly differs from the bundle conveying device 60A in the configuration of the support rollers 52 (corresponding to the first conveying rollers 61).

Thus, in the following description, points different from the aforementioned bundle conveying device 60A are mainly described, and description of the same configuration as the bundle conveying device 60A is omitted.

The first inspection conveyance device 50a2 includes a plurality of support rollers 52, 52 … that support an end portion (in the present embodiment, a right end portion) in a width direction (a direction orthogonal to the conveyance direction) of the lower surface of the sheet glass G, a second drive motor 53 as a power source, a second drive transmission mechanism 54 that transmits the driving force of the second drive motor 53 to the plurality of support rollers 52, 52 …, and the like.

The second drive motor 53 has the same configuration as the first drive motor 62 of the bundle conveying device 60A described above, and therefore, the description thereof is omitted.

The backup roller 52 includes a roller shaft 52a extending in the horizontal direction, an abutment roller 52b inserted through an end of the roller shaft 52a so as to be positioned coaxially therewith, and the like.

Further, a plurality of support rollers 52, 52 … are provided and arranged so as to be aligned in the conveyance direction of the sheet glass G (the direction of arrow a in fig. 3).

Here, a second drive transmission mechanism 54 (described later) is provided at one end (in the present embodiment, the left side when viewed in the conveyance direction of the sheet glass G) of the plurality of support rollers 52, 52 …, and each support roller 52 is coupled to the second drive motor 53 via the second drive transmission mechanism 54.

Further, the abutment rollers 52b and 52b … are disposed at the other end (the right side in the conveying direction of the sheet glass G in the present embodiment) of the plurality of support rollers 52 and 52 …, and the end (right end) in the width direction of the lower surface of the sheet glass G is supported by the abutment rollers 52b and 52b ….

Then, the driving force of the second drive motor 53 is transmitted via the second drive transmission mechanism 54, whereby the plurality of support rollers 52 and 52 … are rotated and driven, respectively, and the sheet glass G is conveyed in the conveying direction (the direction of arrow a) while being supported by the plurality of abutment rollers 52b and 52b ….

An annular cushion member (not shown) made of rubber or resin is attached to the outer peripheral portion of the plurality of abutment rollers 52b, 52b …, and conveyance fluctuation and deviation of the stop position of the sheet glass G are prevented.

The second drive transmission mechanism 54 includes a second intermediate shaft 55, a second drive-side magnetic gear 56, a second driven-side magnetic gear 57, a second timing belt 58, and the like.

The second counter shaft 55, the second driving side magnetic gear 56, the second driven side magnetic gear 57, and the second timing belt 58 have the same configurations as the first counter shaft 64, the first driving side magnetic gear 65, the first driven side magnetic gear 66, and the first timing belt 67 of the bundle conveying device 60A, and therefore, the description thereof is omitted.

However, the first inspection conveying device 50A2 of the present embodiment is further provided with the second cover member 59 that partially surrounds the periphery of the second drive transmission mechanism 54, similarly to the aforementioned bundle conveying device 60A, and is configured to be able to prevent dust floating around the second drive transmission mechanism 54 from entering the gap between the second drive-side magnetic gear 56 and the second driven-side magnetic gear 57, and to more reliably transmit the driving force of the second drive motor 53 to the plurality of support rollers 52, 52 … via the second drive transmission mechanism 54.

In the above-described embodiment, the first inspection conveyance device 50a2 and the second inspection conveyance device 50A3 are both provided with the second drive motor 53, but the present invention is not limited to this embodiment. For example, the second drive motor 53 may be set to 1, and the first inspection conveyance device 50a2 and the second inspection conveyance device 50A3 may be driven in synchronization with each other by a shaft not shown in the figure. The backup rollers 52 of either one of the inspection conveying devices 50A may be driven rollers that rotate as the sheet glass G is conveyed. Further, in order to smoothly inspect the glass sheet G, rollers having the same configuration as the first conveying rollers 61 may be provided before and after the inspection device 50B and inside the inspection device 50C.

[ Structure of cleaning conveyance device 30A ]

Next, the configuration of the cleaning conveyance device 30A will be described in detail with reference to fig. 6.

The washing conveyor device 30A has substantially the same configuration as the aforementioned bundle conveyor device 60A, and mainly differs from the bundle conveyor device 60A in the configuration of the third drive transmission mechanism 33 (corresponding to the first drive transmission mechanism 63).

Thus, in the following description, points different from the conveying device for a bundle are mainly described, and description of the same configuration as the conveying device for a bundle 60A is omitted.

As described above, the cleaning conveyance device 30A is an example of a cleaning roller conveyance device that conveys the glass raw material G1 in a state of being placed on the conveyance roller (third conveyance roller 31) while the glass raw material G1 is cleaned by the cleaning device 30B, and as shown in fig. 6 (a), the cleaning conveyance device 30A mainly includes the plurality of third conveyance rollers 31, 31 … that convey the glass raw material G1, the third drive motor 32 as a power source, the third drive transmission mechanism 33 that transmits the drive force of the third drive motor 32 to the plurality of third conveyance rollers 31, 31 …, and the like.

The third conveying rollers 31 and the third drive motor 32 have the same configurations as the first conveying rollers 61 and the first drive motor 62 of the bundle conveying device 60A described above, and therefore, description thereof is omitted.

The third drive transmission mechanism 33 includes a third intermediate shaft 34, a drive side gear 35, a driven side gear 36, a third timing belt 37, an injection device 38 (see fig. 6 (b)), and the like.

The third intermediate shaft 34 and the third timing belt 37 have the same configurations as the first intermediate shaft 64 and the first timing belt 67 of the aforementioned bundle conveying device 60A, and therefore, the description thereof is omitted.

A plurality of driving side gears 35 and 35 … each formed of a helical gear are coaxially inserted through the third intermediate shaft 34, and the plurality of driving side gears 35 and 35 … are disposed at positions corresponding to the arrangement of the plurality of third conveying rollers 31 and 31 …, respectively.

On the other hand, a plurality of driven side gears 36 and 36 … each formed of a helical gear are inserted into one end (end on the third intermediate shaft 34 side) of each of the third conveying rollers 31 and 31 ….

The driven side gears 36 and 36 … provided to penetrate the third conveying rollers 31 and 31 … are engaged with the plurality of driving side gears 35 and 35 … provided to penetrate the third intermediate shaft 34, respectively.

Thus, the driving force of the third drive motor 32 transmitted to the third intermediate shaft 34 is transmitted to the driving side gear 35 and the driven side gear 36 in this order, and the plurality of third conveyance rollers 31 and 31 … are simultaneously driven to rotate in the same direction.

However, the cleaning conveyance device 30A of the present embodiment further includes a third cover member 39 that partially surrounds the third drive transmission mechanism 33.

Specifically, the third cover member 39 is formed of, for example, a box-shaped member having a rectangular parallelepiped shape, and is disposed so as to surround all of the peripheries of one end portions (end portions on the third intermediate shaft 34 side) of the plurality of third conveying rollers 31 and 31 ….

As a result, the plurality of driving side gears 35, 35 … and driven side gears 36, 36 … that mesh with each other are provided in the third cover member 39.

Here, as shown in fig. 6 (b), the injection device 38 is disposed above the driving side gears 35 and 35 … and the driven side gears 36 and 36 ….

The injection device 38 injects water toward the driving side gears 35, 35 … and the driven side gears 36, 36 …, and the injection device 38 includes, for example, a plurality of injection nozzles 38a, 38a … (only one injection nozzle is shown in fig. 6 (b) is a front view) arranged above the driven gears 36, 36 … (and the driving gears 35, 35 …), a supply pump (not shown) communicating with the injection nozzles 38a, 38a … via a piping member, and the like.

The water discharged from the supply pump is sent to the spray nozzles 38a and 38a … through a pipe member, and then is discharged downward from the discharge ports of the spray nozzles 38a and 38a ….

Accordingly, water is constantly blown into the plurality of driving side gears 35 and 35 … and the driven side gears 36 and 36 … in the third cover member 39, thereby preventing dust generated between the two members from floating around and suppressing an increase in the fraction defective of the glass raw material G1.

That is, in the cleaning conveyance device 30A, for example, since the glass raw material G1 is conveyed in a state where the plurality of brushes 30B1, 30B1 … (see fig. 1) provided in the cleaning device 30B are pushed to the upper surface of the glass raw material G1, a larger driving force is required to rotationally drive the plurality of third conveyance rollers 31, 31 …, and the third drive transmission mechanism 33 required to transmit such a large driving force is normally constituted by the driving side gear 35 and the driven side gear 36 which mesh with each other.

However, in the third drive transmission mechanism 33 configured as described above, dust formed by abrasion is likely to be generated between the driving side gear 35 and the driven side gear 36.

In the present invention, the third drive transmission mechanism 33 configured as described above is provided with the injection device 38 for injecting water into the drive side gear 35 and the driven side gear 36, and even if dust generated by abrasion is generated between the drive side gear 35 and the driven side gear 36, the dust can be washed away by the injected water, and the adhesion of the dust to the glass raw material G1 during cleaning can be suppressed, which leads to an increase in the fraction defective of the glass raw material G1.
