Description

Technical Field

[0001] The present utility model relates to a manufacturing apparatus for a glass plate bundle and a manufacturing apparatus for a glass roll. Background Art

[0002] In the manufacturing process of glass articles, the produced glass articles are usually bundled in a state where a protective sheet composed of a lining paper, a resin sheet, etc. is interposed.

[0003] For example, in the case of a glass article composed of a glass plate, the produced glass plate is bundled as a glass plate bundle formed by successively loading on a tray while interposing a single protective sheet.

[0004] In addition, in the case of a glass article composed of a glass ribbon, the produced glass ribbon is bundled as a glass roll formed by winding in a roll shape while overlappingly interposing a protective sheet blank composed of a strip-shaped protective sheet.

[0005] Here, in such bundles such as a glass plate bundle and a glass roll, if foreign matter (particles) adheres to the surface of the protective sheet (or protective sheet blank), during the conveyance of the bundle to a specified shipping destination or during the temporary storage of the bundle at a specified storage location, the foreign matter is transferred to the surface of the glass plate or glass ribbon, which may cause a deterioration in the quality of these glass plates and glass ribbons.

[0006] Therefore, as an example of a technique for preventing such deterioration in the quality of glass plates and glass ribbons, for example, Patent Document 1 discloses the following technique: During the manufacturing process of the protective sheet, a brush unit composed of a disk brush or the like is used to scrape off foreign matter adhering to both the front and back surfaces of the protective sheet, and the scraped foreign matter is removed by suction using a suction device.

[0010] Problems to be Solved by the Utility Model

[0011] According to the technique in the above Patent Document 1, it is considered that the cleanliness of the freshly manufactured protective sheet (or protective sheet blank) can be ensured, and in bundles such as a glass plate bundle and a glass roll, the deterioration in the quality of the glass plate and glass ribbon can be suppressed to some extent.

[0012] However, the manufactured protective sheet is usually stored at a specified storage location for a certain period, and then conveyed to a bundling process for constructing bundles such as a glass plate bundle and a glass roll.

[0013] Therefore, for example, when the protective sheet (protective sheet blank) is made of a resin sheet, due to changes in conditions such as temperature and humidity in the above storage location, newly exuded additives (such as antioxidants and antistatic agents) are generated as foreign substances on the surface of the protective sheet, which may induce a reduction in the quality of the glass plate or glass ribbon.

[0014] In addition, for example, when the protective sheet (protective sheet blank) is made of paper, due to vibrations applied during transportation to the above bundling process, new paper powder is generated as a foreign substance on the surface of the protective sheet, which may induce a reduction in the quality of the glass plate or glass ribbon.

[0015] The present utility model has been completed in view of the current problems shown above, and its object is to provide a manufacturing apparatus for glass articles, which is a manufacturing apparatus for a glass plate bundle body formed by loading a plurality of glass plates onto a tray while sandwiching a protective sheet. Even when new foreign substances are likely to be generated on the surface of the protective sheet due to changes in conditions such as temperature and humidity in the storage location of the protective sheet or vibrations applied during transportation of the protective sheet, it is possible to suppress a reduction in the quality of each plate glass in the glass bundle body.

[0016] In addition, the object of the present utility model is to provide a manufacturing apparatus for a glass roll, which is a manufacturing apparatus for a glass roll formed by winding a glass ribbon while sandwiching a protective sheet blank. Even when new foreign substances are likely to be generated on the surface of the protective sheet blank due to changes in conditions such as temperature and humidity in the storage location of the protective sheet blank or vibrations applied during transportation of the protective sheet blank, it is possible to suppress a reduction in the quality of the glass ribbon in the glass roll.

[0024] In addition, the manufacturing apparatus for a glass plate bundle package according to the third aspect of the present utility model is characterized in that, based on the first aspect or the second aspect, the protective sheet blank conveyance device has conveyance rollers for conveying the protective sheet blank in the length direction, and the dust removing device is arranged to face the conveyance rollers with the protective sheet blank sandwiched therebetween, and the dust removing device removes foreign matters on the surface of the protective sheet blank on the side opposite to the contact surface contacting the conveyance roller side.

[0025] By having such a structure, in the manufacturing apparatus for a glass plate bundle package according to the present utility model, by bringing the protective sheet blank into contact with the conveyance rollers, it is possible to suppress the swaying during conveyance of the protective sheet blank, and to suppress the generation of wrinkles, breakages, etc., and to remove new foreign matters from the protective sheet (protective sheet blank) in a stable state.

[0073] Next, use Figures 1 to 3 to describe an implementation mode of the present utility model.

[0074] It should be noted that in the following description, for convenience, the front-back direction, left-right direction, and up-down direction in the manufacturing device 1, 201 of the glass plate package M or the manufacturing device 301 of the glass roll R are defined by the direction of the arrow shown in Figures 1 to 3 and are described.

[0075] [Overall structure of the manufacturing device 1 (first implementation mode) of the glass plate package M]

[0076] First, use Figure 1 to describe the overall structure of the manufacturing device 1 (hereinafter, only recorded as "manufacturing device 1") of the glass plate package M in the first implementation mode of the present utility model.

[0077] The manufacturing device 1 in this implementation mode is a device that is arranged in the manufacturing process of glass articles composed of glass plates G, and while sandwiching single-piece protective sheets Sa, Sa..., loads the produced multiple glass plates G, G... onto the tray 100 in sequence and packs them, thereby constructing the glass plate package M.

[0078] Here, the protective sheet Sa is composed of a foamed or non-foamed resin sheet, lining paper, etc., and is formed by cutting a strip-shaped protective sheet blank S into a specified outer dimension.

[0079] It should be noted that regarding the raw material of the protective sheet Sa, there is no particular limitation, and any raw material can be used as long as it can suppress the occurrence of damage, breakage, etc. to the bundled glass plates G.

[0080] As the raw material of the protective sheet Sa, it can be a foamed resin sheet such as foamed polyethylene or foamed polystyrene, a non-foamed resin sheet, pulp paper, etc.

[0081] In addition, the tray 100 has a back surface portion 101 that is slightly inclined with respect to the vertical plane and a bottom surface portion 102 that is connected to the lower end surface of the back surface portion 101, and multiple glass plates G, G... are loaded onto the bottom surface portion 102 in a vertically placed posture leaning against the back surface portion 101.

[0082] It should be noted that the structure of the tray 100 is not limited to this implementation mode. For example, it can also be a structure having a bottom surface portion with an outer dimension slightly larger than the outer dimension of the glass plate G and loading multiple glass plates G, G... in a horizontally placed posture on the bottom surface portion.

[0083] The manufacturing apparatus 1 mainly includes: a glass plate loading device 10 that loads a plurality of glass plates G, G... onto a tray 100; and a protective sheet supply device 20 that supplies a protective sheet Sa between a pair of glass plates G, G adjacent to each other on the tray 100.

[0084] The glass plate loading device 10 has a first clamping mechanism portion 11 capable of clamping the upper end portion of the glass plate G.

[0085] In addition, the first clamping mechanism portion 11 is arranged to be able to reciprocate between a supply position P1 where the glass G produced in the previous process is sequentially supplied and a bundling position P2 where the tray 100 is arranged.

[0086] And, after the glass plate loading device 10 clamps the glass plate G by the first clamping mechanism portion 11 at the supply position P1, it moves the first clamping mechanism portion 11 to the bundling position P2 and releases the clamping state of the first clamping mechanism portion 11, thereby transferring the glass plate G onto the tray 100.

[0087] The protective sheet supply device 20 includes: a protective sheet blank handling device 21 that handles a strip-shaped protective sheet blank S; a protective sheet blank cutting device 22 that cuts out a single protective sheet Sa from the protective sheet blank S; a protective sheet loading device 23 that loads the protective sheet Sa between a pair of glass plates G, G; and a dust removing device 24 that removes foreign matter adhering to the surface of the protective sheet Sa.

[0088] The protective sheet blank handling device 21 has a handling roller 21a that feeds out and handles the protective sheet blank S wound in a roll shape (hereinafter, appropriately referred to as "protective sheet blank wound body SM") in the length direction.

[0089] The handling roller 21a has: a pair of upstream feeding rollers 21a1, 21a1, which are arranged near the protective sheet blank wound body SM; a pair of downstream feeding rollers 21a2, 21a2, which are adjacent to the protective sheet blank cutting device 22 on the upstream side in the handling direction ( Figure 1 the direction of arrow A in); and a plurality (4 in this embodiment) of guide rollers 21a3, 21a3..., which are arranged between the upstream feeding rollers 21a1 and the downstream feeding rollers 21a2 and change the orientation of the handling direction of the protective sheet blank S.

[0090] And, the protective sheet blank S is fed out in the length direction from the protective sheet blank wound body SM in a state of being clamped by the pair of upstream feeding rollers 21a1, 21a1, and then winds around the outer circumferential surfaces of the plurality of guide rollers 21a3, 21a3... to change the orientation of the handling direction and reaches the pair of downstream feeding rollers 21a2, 21a2.

[0091] In addition, the protective sheet blank S that reaches the pair of downstream delivery rollers 21a2, 21a2 is clamped again by the pair of downstream delivery rollers 21a2, 21a2 and sent out toward the protective sheet blank cutting device 22 side (i.e., the downstream side in the conveying direction).

[0092] The protective sheet blank cutting device 22 has a cutting edge 22a for cutting the protective sheet blank S and a cutting auxiliary member 22b for assisting the cutting operation performed by the cutting edge 22a.

[0093] The cutting edge 22a is disposed near the downstream side in the conveying direction with respect to the pair of downstream delivery rollers 21a2, 21a2 and on the first surface S1 side (front side in the present embodiment) of the protective sheet blank S sent out from the pair of downstream delivery rollers 21a2, 21a2, and is configured to extend along the width direction of the protective sheet blank S (the direction orthogonal to the length direction, the left - right direction in the present embodiment).

[0094] In addition, the cutting auxiliary member 22b extends along the width direction of the protective sheet blank S on the second surface S2 side (rear side in the present embodiment) of the protective sheet blank S sent out from the pair of downstream delivery rollers 21a2, 21a2, and is disposed opposite to the cutting edge 22a with the protective sheet blank S sandwiched therebetween.

[0095] Here, in the cutting auxiliary member 22b, a groove portion 22b1 extending along the extending direction of the cutting auxiliary member 22b (the left - right direction in the present embodiment) is formed on the opposing surface opposite to the cutting edge 22a.

[0096] In addition, the cutting edge 22a is provided so as to be movable relative to the cutting auxiliary member 22b in the approaching direction (the rear direction in the present embodiment) and the separating direction (the front direction in the present embodiment). By moving in the approaching direction, the tip of the cutting edge 22a can be immersed in the groove portion 22b1.

[0097] And when the length of the protective sheet blank S sent out by the pair of downstream delivery rollers 21a2, 21a2 reaches a specified length, the cutting edge 22a moves in the approaching direction.

[0098] Thereby, a single - sheet protective sheet Sa having a specified outer dimension is cut out from the protective sheet blank S.

[0099] The protective sheet loading device 23 has a pair of second clamping mechanism portions 23a, 23a ( Figure 1 Since it is a side view, only one second clamping mechanism portion is shown) and a pair of third clamping mechanism portions 23b, 23b ([[]] Figure 1is a side view, so only one third clamping mechanism part is shown).

[0100] A pair of second clamping mechanism parts 23a, 23a are configured to be able to clamp both ends in the width direction of the protective sheet blank S fed out from a pair of downstream feeding rollers 21a2, 21a2 near the downstream side in the conveying direction with respect to the protective sheet blank cutting device 22.

[0101] In addition, a pair of third clamping mechanism parts 23b, 23b are configured to be able to clamp both ends in the width direction of the protective sheet blank S fed out from a pair of downstream feeding rollers 21a2, 21a2 near the downstream side in the conveying direction with respect to a pair of second clamping mechanism parts 23a, 23a.

[0102] And the protective sheet loading device 23 supplies the protective sheet Sa cut out from the protective sheet blank S between a pair of glass plates G, G on the tray 100 in the following order.

[0103] That is, when the front end of the protective sheet blank S fed out from a pair of downstream feeding rollers 21a2, 21a2 reaches a pair of third clamping mechanism parts 23b, 23b, the pair of downstream feeding rollers 21a2, 21a2 temporarily stop the feeding operation of the protective sheet blank S.

[0104] When the pair of downstream feeding rollers 21a2, 21a2 stop the feeding operation, a pair of third clamping mechanism parts 23b, 23b clamp both ends in the width direction of the front end of the protective sheet blank S.

[0105] Then, a pair of third clamping mechanism parts 23b, 23b pull out the protective sheet blank S toward the downstream side in the conveying direction (substantially the lower side in this embodiment), and the pair of downstream feeding rollers 21a2, 21a2 start the feeding operation again, and feed out the protective sheet blank S synchronously with the pulling out operation of the protective sheet blank S by the pair of third clamping mechanism parts 23b, 23b.

[0106] When the length of the protective sheet blank pulled out by a pair of third clamping mechanism parts 23b, 23b reaches a specified length, the pair of third clamping mechanism parts 23b, 23b stop the pulling out operation.

[0107] In addition, in cooperation with the pair of third clamping mechanism parts 23b, 23b stopping the pulling out operation, the pair of downstream feeding rollers 21a2, 21a2 stop the feeding operation again.

[0108] Then, near the protective sheet blank cutting device 22, a pair of third clamping mechanism parts 23b, 23b clamp both ends in the width direction of the protective sheet blank S.

[0109] Accordingly, the protective sheet blank S fed out from a pair of downstream feed rollers 21a2, 21a2 is held in a state where both end portions in the width direction are clamped by a pair of second clamping mechanism portions 23a, 23a and a pair of third clamping mechanism portions 23b, 23b near the downstream side in the conveying direction with respect to the protective sheet blank cutting device 22.

[0110] When the protective sheet blank S is held by a pair of second clamping mechanism portions 23a, 23a and a pair of third clamping mechanism portions 23b, 23b, the protective sheet blank cutting device 22 is movable, and a single protective sheet Sa is cut out from the protective sheet blank S.

[0111] When cutting out the protective sheet Sa, a pair of second clamping mechanism portions 23a, 23a and a pair of third clamping mechanism portions 23b, 23b move to a specified position on the tray 100 located at the bundling position P2 while holding the protective sheet Sa, and then release the holding state.

[0112] Accordingly, the protective sheet Sa is supplied between a pair of glass plates G, G on the tray 100 by the protective sheet loading device 23.

[0113] The dust removing device 24 includes: a first dust removing device 24a that removes foreign matter adhering to the first surface S1 of the protective sheet blank S; and a second dust removing device 24b that removes foreign matter adhering to the second surface S2 on the side opposite to the surface S1.

[0114] In this embodiment, for example, the first dust removing device 24a is constituted by an ultrasonic dust removing mechanism that jets and sucks compressed air undergoing ultrasonic vibration, and has a gas jet portion 24a1 that jets compressed air and a gas suction portion 24a2 that sucks the compressed air jetted from the gas jet portion 24a1.

[0115] In addition, the second dust removing device 24b is also constituted by the above ultrasonic dust removing mechanism in the same manner as the first dust removing device 24a, and has a gas jet portion 24b1 that jets compressed air and a gas suction portion 24b2 that sucks the compressed air jetted from the gas jet portion 24b1.

[0116] The first dust removing device 24a and the second dust removing device 24b are arranged on the conveying path for conveying the protective sheet blank S by the protective sheet blank conveying device 21 (that is, on the conveying path indicated by the arrow A), and are arranged opposite to the conveying roller 21a with the protective sheet blank S sandwiched therebetween.

[0117] Specifically, the first dust removing device 24a causes the gas ejection part 24a1 and the gas suction part 24b2 to face a specified guide roller 21a3 (hereinafter, appropriately referred to as "first guide roller 21a3a") among the conveying rollers 21a, and is disposed opposite to the first guide roller 21a3a with the protective sheet blank S sandwiched therebetween.

[0118] In addition, the second dust removing device 24b causes the gas ejection part 24b1 and the gas suction part 24b2 to face a guide roller 21a3 (hereinafter, appropriately referred to as "second guide roller 21a3b") adjacent to the downstream side in the conveying direction with respect to the first guide roller 21a3a, and is disposed opposite to the second guide roller 21a3b with the protective sheet blank S sandwiched therebetween.

[0119] Moreover, the first dust removing device 24a is configured to remove foreign matters on the surface (the first surface S1 in the present embodiment) of the protective sheet blank S on the side opposite to the contact surface in contact with the first guide roller 21a3a side without contacting the protective sheet blank S.

[0120] In addition, the second dust removing device 24b is configured to remove foreign matters on the surface (the second surface S2 in the present embodiment) of the protective sheet blank S on the side opposite to the contact surface in contact with the second guide roller 21a3b side without contacting the protective sheet blank S.

[0121] In this way, the dust removing device 24 (more specifically, the first dust removing device 24a and the second dust removing device 24b) in the present embodiment is configured to include: gas ejection parts 24a1, 24b1 that eject compressed air to the surface (the first surface S1 or the second surface S2) of the protective sheet blank S; and gas suction parts 24a2, 24b2 that suck the compressed air ejected from the gas ejection parts 24a1, 24b1.

[0122] With such a structure, according to the manufacturing device 1 in the present embodiment, the foreign matters attached to the surface of the protective sheet blank S are detached by the compressed air ejected from the gas ejection parts 24a1, 24b1, and by sucking the compressed air containing the detached foreign matters by the gas suction parts 24a2, 24b2, new foreign matters can be more effectively removed from the protective sheet Sa (more specifically, the protective sheet blank S).

[0123] In addition, since new foreign matters are removed from the protective sheet Sa (protective sheet blank S) without directly contacting the protective sheet blank S, damage and breakage of the protective sheet Sa due to the dust removing operation using the dust removing device 24 can be prevented.

[0124] In addition, in the present embodiment, the dust removal device 24 including the first dust removal device 24a and the second dust removal device 24b is respectively arranged on the conveying path for conveying the protective sheet blank S by the protective sheet blank conveying device 21.

[0125] Here, as described above, the single-piece protective sheet Sa cut out by the protective sheet blank cutting device 22 is moved to a specified position (i.e., the specified position on the tray 100 located at the bundling position P2) by the protective sheet loading device 23, and then loaded between a pair of glass plates G, G.

[0126] In addition, the protective sheet loading device 23 has a pair of second clamping mechanism parts 23a, 23a and a pair of third clamping mechanism parts 23b, 23b that move while clamping both end parts in the width direction of the protective sheet Sa. Generally, the structure is complex, and it is sometimes difficult to ensure the space for dust removal of the protective sheet Sa.

[0127] In the manufacturing device 1 in the present embodiment, since the dust removal device 24 (the first dust removal device 24a and the second dust removal device 24b) is arranged on the conveying path of the protective sheet blank conveying device 21 for conveying the protective sheet blank S before cutting out the protective sheet Sa, it is relatively easy to ensure the space for dust removal of the protective sheet Sa (more specifically, the protective sheet blank S), and new foreign matters can be removed from the protective sheet Sa more reliably.

[0128] In addition, in the present embodiment, the protective sheet blank conveying device 21 has a conveying roller 21a for conveying the protective sheet blank S in the length direction. The dust removal device 24 (the first dust removal device 24a and the second dust removal device 24b) is arranged opposite to the conveying roller 21a with the protective sheet blank S sandwiched therebetween, and is configured to remove foreign matters on the surface of the protective sheet blank S on the side opposite to the contact surface contacting the conveying roller 21a side.

[0129] With such a structure, according to the manufacturing device 1 in the present embodiment, by bringing the protective sheet blank S into contact with the conveying roller 21a, it is possible to suppress the shaking during the conveyance of the protective sheet blank S, and suppress the generation of wrinkles, breakage, etc., and remove new foreign matters from the protective sheet Sa (protective sheet blank S) in a stable state.

[0130] And, in the present embodiment, the dust removal device 24 is configured to include: a first dust removal device 24a that removes foreign matters attached to the first surface S1 of the protective sheet blank S; and a second dust removal device 24b that removes foreign matters attached to the second surface S2 of the protective sheet blank S located on the side opposite to the first surface S1.

[0131] Thus, in the manufacturing apparatus 1 of the present embodiment, it is configured to remove dust from the first surface S1 and the second surface S2 of the protective sheet blank S by using the first dust removal device 24a and the second dust removal device 24b, and new foreign matters can be more effectively removed from the protective sheet Sa (protective sheet blank S).

[0132] It should be noted that, in the present embodiment, two dust removal devices 24, 24 including the first dust removal device 24a and the second dust removal device 24b are provided, but it is not limited thereto, and one dust removal device 24 may also be provided.

[0133] In this case, the dust removal device 24 is arranged so as to be able to remove dust from the surface of the protective sheet blank S on the side in contact with the guaranteed surface (the surface on the side processed as a product) of the glass plate G.

[0134] In addition, in the present embodiment, two dust removal devices 24, 24 including the first dust removal device 24a and the second dust removal device 24b are provided, but three or more dust removal devices 24 may also be provided.

[0135] That is, in the present embodiment, the conveying roller 21a has a plurality of guide rollers 21a3, 21a3... that change the conveying direction (the direction of arrow A) of the protective sheet blank S, and the protective sheet supply device 20 is configured to have two or more dust removal devices 24 (in the present embodiment, the first dust removal device 24a and the second dust removal device 24b) arranged opposite to two or more of the guide rollers 21a3, 21a3... (in the present embodiment, the first guide roller 21a3a and the second guide roller 21a3b).

[0136] With such a structure, according to the manufacturing apparatus 1 in the present embodiment, new foreign matters can be more reliably removed from the protective sheet Sa (protective sheet blank S) by using two or more dust removal devices 24 (the first dust removal device 24a and the second dust removal device 24b).

[0137] [Overall Structure of the Manufacturing Apparatus 201 (Second Embodiment) of the Glass Plate Bundle M]

[0138] Next, use Figure 2 to describe the overall structure of the manufacturing apparatus 201 (hereinafter, only referred to as "manufacturing apparatus 201") of the glass plate bundle M according to the second embodiment of the present utility model.

[0139] The manufacturing apparatus 201 in the second embodiment is another embodiment of the manufacturing apparatus 1 in the foregoing first embodiment, and has a structure substantially equivalent to that of the manufacturing apparatus 1. On the other hand, the arrangement position of the dust removal device 224 is different from that of the manufacturing apparatus 1.

[0140] Therefore, in the following description, the differences from the manufacturing apparatus 1 in the first embodiment will be mainly described, and the description of the structures equivalent to the manufacturing apparatus 1 will be omitted.

[0141] The manufacturing apparatus 201 mainly includes: a glass plate loading device 210 that loads a plurality of glass plates G, G,... onto a tray 100; and a protective sheet supply device 220 that supplies a protective sheet Sa between a pair of adjacent glass plates G, G on the tray 100.

[0142] It should be noted that the glass plate loading device 210 has a structure substantially equivalent to the glass plate loading device 10 in the aforementioned manufacturing apparatus 1, and thus the description thereof is omitted.

[0143] The protective sheet supply device 220 includes: a protective sheet blank conveying device 221 that conveys a strip-shaped protective sheet blank S; a protective sheet blank cutting device 222 that cuts out a single protective sheet Sa from the protective sheet blank S; a protective sheet loading device 223 that loads the protective sheet Sa between a pair of glass plates G, G; and a dust removing device 224 that removes foreign matters adhering to the surface of the protective sheet Sa.

[0144] It should be noted that the protective sheet blank conveying device 221, the protective sheet blank cutting device 222, and the protective sheet loading device 223 have structures substantially equivalent to the protective sheet blank conveying device 21, the protective sheet blank cutting device 22, and the protective sheet loading device 23 in the aforementioned manufacturing apparatus 1, respectively, and thus the description thereof is omitted.

[0145] The dust removing device 224 includes: a third dust removing device 224a that removes foreign matters adhering to the first surface S1 of the protective sheet blank S; and a fourth dust removing device 224b that removes foreign matters adhering to the second surface S2 located on the side opposite to the surface S1.

[0146] It should be noted that the third dust removing device 224a and the fourth dust removing device 224b have structures substantially equivalent to the first dust removing device 24a and the second dust removing device 24b in the aforementioned manufacturing apparatus 1, respectively, and thus the description thereof is omitted.

[0147] The third dust removing device 224a is located on the downstream side in the conveying direction (the direction of arrow A) of the protective sheet blank conveying device 221 with respect to the protective sheet blank cutting device 222, and is arranged in a state where the gas ejection part 24a1 and the gas suction part 24b2 face the first surface S1 of the protective sheet blank S sent out from a pair of downstream sending rollers 221a2, 221a2.

[0148] In other words, the third dust removing device 224a is arranged so as to be able to face the first surface S1 of the protective sheet Sa cut out by the protective sheet blank cutting device 222.

[0149] Further, the fourth dust removing device 224b is located on the downstream side in the conveying direction (the direction of arrow A) of the protective sheet blank conveying device 221 with respect to the protective sheet blank cutting device 222, and is arranged such that the gas ejection part 224b1 and the gas suction part 224b2 face the second surface S2 of the protective sheet blank S sent out from the pair of downstream conveying rollers 221a2, 221a2.

[0150] In other words, the fourth dust removing device 224b is arranged to be able to face the second surface S2 of the protective sheet Sa cut out by the protective sheet blank cutting device 222.

[0151] Thus, in the present embodiment, the dust removing device 224 (more specifically, the third dust removing device 224a and the fourth dust removing device 224b) is configured to be located on the downstream side in the conveying direction of the protective sheet blank conveying device 221 with respect to the protective sheet blank cutting device 222, and is arranged to be able to face the surfaces (the first surface S1 and the second surface S2) of the protective sheet Sa cut out by the protective sheet blank cutting device 222.

[0152] With such a structure, according to the manufacturing device 201 in the present embodiment, even when foreign matters composed of cutting powder generated when cutting the protective sheet Sa from the protective sheet blank S by the protective sheet blank cutting device 222 adhere to the surface of the protective sheet Sa, the foreign matters can be removed by the dust removing device 224, so that the foreign matters can be more reliably removed from the protective sheet Sa.

[0153] As described above, the manufacturing device 1 (201) of the first embodiment (or the second embodiment) of the present utility model is a manufacturing device for a glass plate bundle M in which a plurality of glass plates G, G... are loaded on a tray 100 while sandwiching the protective sheet Sa, and includes: a glass plate loading device 10 (210) that loads a plurality of glass plates G, G... on the tray 100; and a protective sheet supply device 20 (220) that supplies the protective sheet Sa between a pair of adjacent glass plates G, G.

[0154] And the protective sheet supply device 20 (220) is configured to include: a protective sheet blank conveying device 21 (221) that conveys a strip-shaped protective sheet blank S; a protective sheet blank cutting device 22 (222) that cuts out a single protective sheet Sa from the protective sheet blank S; and a protective sheet loading device 23 (223) that places the protective sheet Sa between a pair of glass plates G, G, and also has a dust removing device 24 (224) that removes foreign matters adhering to the surface (the first surface S1 or the second surface S2) of the protective sheet Sa.

[0155] By having such a structure, even when new foreign matters are re-generated on the surface (the first surface S1 or the second surface S2) of the protective sheet Sa before it is used for the glass plate bundle M due to changes in conditions such as temperature and humidity in the storage location or vibrations applied during transportation to the bundling process (for example, paper powder generated in the protective sheet Sa made of lining paper, exuded additives (antioxidants, antistatic agents, etc.) generated in the protective sheet Sa made of resin sheet, etc.), when the protective sheet Sa is supplied by the protective sheet supply devices 20 and 220, the dust removal devices 24 and 224 can be used to remove the new foreign matters from the protective sheet Sa again.

[0156] Therefore, it is possible to extremely prevent foreign matters from being transferred from the protective sheet Sa to the surface of the glass plate G, and to suppress the deterioration of the quality of the glass plate G.

[0157] [Overall Structure of the Manufacturing Device 301 for the Glass Roll R]

[0158] Next, Figure 3 The overall structure of the manufacturing device 301 for the glass roll R of the present invention (hereinafter, only referred to as "manufacturing device 301") will be described.

[0159] The manufacturing device 301 in the present embodiment is a device that is provided in the manufacturing process of a glass article composed of a glass ribbon L, and winds and bundles the produced glass ribbon L while sandwiching a strip-shaped protective sheet blank, thereby constructing a glass roll R.

[0160] It should be noted that the manufacturing device 301 in the present embodiment has a structure substantially equivalent to that of the manufacturing device 1 in the foregoing first embodiment. On the other hand, it is different from the manufacturing device 1 in that a glass ribbon manufacturing device 330 is provided in place of the downstream delivery roller 21a2, the protective sheet blank cutting device 22, and the protective sheet loading device 23 in the glass plate loading device 10 and the protective sheet supply device 20.

[0161] Therefore, in the following description, the differences from the manufacturing device 1 in the first embodiment will be mainly described, and the description of the structure equivalent to that of the manufacturing device 1 will be omitted.

[0162] The manufacturing device 301 mainly includes: a protective sheet blank supply device 320 that supplies a strip-shaped protective sheet blank S; and a glass ribbon manufacturing device 330 that continuously manufactures a strip-shaped glass ribbon L, and winds the glass ribbon L into a roll shape while overlappingly sandwiching the protective sheet blank S, thereby constructing a glass roll R.

[0163] The protective sheet blank supply device 320 includes a protective sheet blank transfer device 321 for transferring the protective sheet blank S and a dust removal device 324 for removing foreign matter attached to the surface of the protective sheet blank S.

[0164] The protective sheet blank transfer device 321 has a transfer roller 321a that feeds out the wound protective sheet blank roll body SM in the length direction for transfer.

[0165] In addition, the transfer roller 321a has a pair of upstream feed rollers 321a1, 321a1 disposed near the protective sheet blank roll body SM, and a plurality (four in this embodiment) of guide rollers 321a3, 321a3... disposed downstream of the pair of upstream feed rollers 321a1, 321a1 in the transfer direction ( Figure 3 the direction of arrow B in the figure), changing the orientation of the transfer direction of the protective sheet blank S.

[0166] And the protective sheet blank S is fed out in the length direction from the protective sheet blank roll body SM while being clamped by the pair of upstream feed rollers 321a1, 321a1, and then wound around the outer circumferential surfaces of the plurality of guide rollers 321a3, 321a3... to change the orientation of the transfer direction, and is supplied to the winding device 335 described later.

[0167] The dust removal device 324 has a fifth dust removal device 324a for removing foreign matter attached to the first surface S1 of the protective sheet blank S, and a sixth dust removal device 324b for removing foreign matter attached to the second surface S2 located on the side opposite to the surface S1.

[0168] It should be noted that the structures and arrangement positions of the fifth dust removal device 324a and the sixth dust removal device 324b are substantially the same as those of the first dust removal device 24a and the second dust removal device 24b in the aforementioned manufacturing device 1, respectively, so the description thereof is omitted.

[0169] The glass ribbon manufacturing device 330, for example, has a forming device 331 that continuously forms a ribbon-shaped glass ribbon L from molten glass La by the overflow down-draw method, a direction conversion device 332 that changes the transfer direction of the glass ribbon L ( Figure 3 the direction in the view C in the figure) from a substantially vertical direction to a substantially horizontal direction, a glass ribbon transfer device 333 that continues to transfer the glass ribbon L from the direction conversion device 332, an ear cutting device 334 that removes unnecessary portions at both ends in the width direction of the glass ribbon L, and a winding device 335 that winds the glass ribbon L and the protective sheet blank S in an overlapping state to construct a glass roll R.

[0170] It should be noted that the glass ribbon manufacturing apparatus 330 in this embodiment is configured with the structure of a general glass ribbon manufacturing apparatus based on the overflow down-draw method, and thus the description thereof will be omitted.

[0171] Thus, the manufacturing apparatus 301 in this embodiment is a manufacturing apparatus for a glass roll R formed by winding a glass ribbon L while sandwiching a protective sheet blank S, and is configured to include: a glass ribbon conveying device 333 that conveys a strip-shaped glass ribbon L; a protective sheet blank conveying device 321 that conveys a strip-shaped protective sheet blank S; and a winding device 335 that winds the glass ribbon L and the protective sheet blank S in a state of overlapping each other. The manufacturing apparatus 301 further includes a dust removing device 324 that removes foreign matter adhering to the surface (the first surface S1 or the second surface S2) of the protective sheet blank S.

[0172] With such a structure, according to the manufacturing apparatus 301 in this embodiment, even when new foreign matter (for example, paper powder generated in the protective sheet blank S made of liner paper, exuded additives (antioxidants, antistatic agents, etc.) generated in the protective sheet blank S made of resin sheet, etc.) is generated again on the surface (the first surface S1 or the second surface S2) of the protective sheet blank S before the glass roll R due to changes in conditions such as temperature and humidity in the storage location or vibrations applied during transportation to the bundling process, the dust removing device 324 can remove this new foreign matter from the protective sheet blank S again when the protective sheet blank S and the glass ribbon L are wound together by the winding device 335.

[0173] Therefore, it is possible to extremely prevent the transfer of foreign matter from the protective sheet blank S to the surface of the glass ribbon L, and suppress the deterioration of the quality of the glass ribbon L.

[0174] [Verification experiment]

[0175] Next, a verification experiment conducted to confirm the effectiveness of the present utility model will be described.

[0176] [Compare the amount of particles attached to the protective sheet Sa]

[0177] First, in the manufacturing apparatus 1 in the first embodiment, 10 protective sheets Sa were produced in a state where the dust removing device 24 was operating, and were prepared as Experimental Example 1.

[0178] In addition, in the manufacturing apparatus 1, 10 protective sheets Sa were produced in a state where the dust removing device 24 was stopped, and were prepared as Experimental Example 2.

[0179] It should be noted that the protective sheet Sa in Experimental Example 1 and the protective sheet Sa in Experimental Example 2 are both made of liner paper, and their outer dimensions are 2580 mm × 2280 mm, respectively.

[0180] Next, fold these prepared protective sheets Sa, put each one into a plastic bag, and then, with the unsealed opening closed, swing each plastic bag continuously 10 times.

[0181] Then, using a particle detector, measure the amount of particles (foreign substances) floating (i.e., adhering to the protective sheet Sa) in each plastic bag, and calculate the average value of the measured values in the 10 plastic bags containing the protective sheet Sa in Experimental Example 1 and the average value of the measured values in the 10 plastic bags containing the protective sheet Sa in Experimental Example 2 respectively, and compare the two.

[0182] It should be noted that when comparing the two, further set the average value of the particle amount in Experimental Example 2 to 100%, and calculate the particle amount in Experimental Example 1 relative to the average value in Experimental Example 2. The results are shown in Table 1.

[0183] [Table 1]

[0184] Amount of particles Experimental Example 1 38.9％ Experimental Example 2 100％

[0185] As shown in Table 1, the average value of the amount of particles adhering to the protective sheet Sa in Experimental Example 1 dusted by the dust removal device 24 is 38.9% which is a reduction of about 60% compared to the average value of the amount of particles adhering to the protective sheet Sa in Experimental Example 2 not dusted by the dust removal device 24.

[0186] <Comparison of the amount of particles adhering to the glass plate G after transportation>

[0187] First, in the manufacturing apparatus 1 in the first embodiment, construct a glass plate bundle M with the dust removal device 24 operating, and prepare it as Experimental Example 3.

[0188] In addition, in the manufacturing apparatus 1 in the first embodiment, construct a glass plate bundle M with the dust removal device 24 stopped, and prepare it as Experimental Example 4.

[0189] It should be noted that in the glass plate bundle M in Experimental Example 3 and the glass plate bundle M in Experimental Example 4, 360 sheet glass plates G are respectively loaded in a flat position state.

[0190] In addition, in the glass plate bundle M in Experimental Example 3 and the glass plate bundle M in Experimental Example 4, protective sheets Sa made of lining paper are both used.

[0191] Next, transport these prepared glass plate bundles M by land using a specified transport vehicle respectively, and then, using a specified cleaning liquid, clean each glass plate G in each glass plate bundle M one by one.

[0192] It should be noted that the driving distance of the transport vehicle during land transportation is about 200 Km.

[0193] Then, using a particle detector, the amount of particles (foreign matter) remaining in the cleaning liquid (i.e., attached to the glass plate G) is measured for each glass plate G, and the average value of the measured values in the cleaning liquid when cleaning the glass plates G in the glass plate bundle M of cleaning experiment example 3 and the average value of the measured values in the cleaning liquid when cleaning the glass plates G in the glass plate bundle M of cleaning experiment example 4 are calculated respectively, and the two are compared.

[0194] It should be noted that, as the object of measurement of the amount of particles, in the glass plate bundle M in experiment example 3 and the glass plate bundle M in experiment example 4, each cleaning liquid after cleaning 60 glass plates G loaded successively from the lowermost layer is taken as the object of measurement.

[0195] In addition, when comparing the two, the average value of the amount of particles in experiment example 4 is further set to 100%, and the average value of the amount of particles in experiment example 3 relative to the average value in experiment example 4 is calculated. The results are shown in Table 2.

[0196] [Table 2]

[0197] Loading position Amount of particles Experimental Example 3 1～60 91.6％ Experimental Example 4 1～60 100％

[0198] As shown in Table 2, the average value of the amount of particles attached to the glass plate G in the glass plate bundle M of experiment example 3 dusted by the dust removal device 24 is 91.6% which is about 10% less than the average value of the amount of particles attached to the glass plate G in the glass plate bundle M of experiment example 4 not dusted by the dust removal device 24.

[0199] <Amount of particles attached to the glass plate G when comparing the processing steps at the shipping destination>

[0200] First, in the manufacturing device 1 in the first embodiment, a glass plate bundle M is constructed in a state where the dust removal device 24 is operating, and it is prepared as experiment example 5.

[0201] In addition, in the manufacturing device 1 in the first embodiment, a glass plate bundle M is constructed in a state where the dust removal device 24 is stopped, and it is prepared as experiment example 6.

[0202] It should be noted that, in the glass plate bundle M in experiment example 5 and the glass plate bundle M in experiment example 6, a protective sheet Sa made of lining paper is used.

[0203] Next, at a specified shipping destination, these prepared glass plate bundles M are unpacked, and for example, the glass plates G in each glass plate bundle M are put into a processing step of performing film formation processing.

[0204] It should be noted that the number of glass plates G input into the processing process is 1077 in the case of the glass plate G in the glass plate package M of Experimental Example 5, and 720 in the case of the glass plate G in the glass plate package M of Experimental Example 6.

[0205] Then, during the cleaning operation using the cleaning liquid in the above processing process, a particle detector was used to measure the amount of particles (foreign substances) remaining in the cleaning liquid (i.e., attached to the glass plate G) for each glass plate G, and the average value of the measured values in the cleaning liquid when cleaning the glass plate G in the glass plate package M of Experimental Example 5 and the average value of the measured values in the cleaning liquid when cleaning the glass plate G in the glass plate package M of Experimental Example 6 were calculated respectively, and the two were compared.

[0206] It should be noted that when comparing the two, the average value of the particle amount in Experimental Example 6 was set to 100%, and the particle amount in Experimental Example 5d relative to the average value of Experimental Example 6 was calculated. The results are shown in Table 3.

[0207] [Table 3]

[0208] Number of sheets inserted Amount of particles Experimental Example 5 1077 sheets 35.6％ Experimental Example 6 720 sheets 100％

[0209] As shown in Table 3, the average value of the amount of particles attached to the glass plate G in the glass plate package M of Experimental Example 5 dusted by the dust removal device 24 is 35.6% which is about 65% less than the average value of the amount of particles attached to the glass plate G in the glass plate package M of Experimental Example 6 not dusted by the dust removal device 24.

[0210] The above describes an embodiment that embodies the present invention, but the present invention is not completely limited by such an embodiment. It is only an illustration. Of course, within the scope not departing from the gist of the present invention, it can be further implemented in various ways. The scope of the present invention is shown by the description of the utility model technical solution, and also includes the equivalent meanings and all changes within the scope recorded in the utility model technical solution.
