Description

  When producing laminated glass having a resin layer in the middle for use in buildings, the present invention removes air from laminated glass used to remove the air that has entered between laminated glass filled with liquid resin between a pair of opposed glass panels. The present invention relates to a table and an air bleeding method for laminated glass using the table.

  As this kind of laminated glass, for example, the outer periphery of a pair of opposed glass panels is sealed and filled with liquid resin between them, and then the excess liquid resin is discharged and removed by pressing the glass panel surface, and then thermosetting, Proposals have been made in which a liquid resin between glass panels is cured by applying a resin curing measure such as ultraviolet curing to manufacture the liquid resin.

JP-A-5-330863

  In this case, the liquid resin is filled with a predetermined amount or more with respect to the filling volume of the laminated glass, and the excess liquid resin is removed by a pressing process, so that the liquid resin is wasted and removed accordingly. Work such as disposal of the liquid resin is required.

  At this time, if a predetermined amount of the liquid resin corresponding to the filling volume of the laminated glass is filled, it is possible to eliminate the waste of the liquid resin. In such a state, the glass is injected between the glass panels from above, and as a result of bending to cause the laminated glass to spread outward due to the weight of the liquid resin in the middle of filling, the filling volume is reduced. The space between the laminated glasses cannot be filled with a predetermined amount of liquid resin, and an air space formed by the difference between the filling volume and the amount of liquid resin will be formed. This will result in product defects that contain air.

  Therefore, it is necessary to vent the air with the liquid resin filled, but the air space is formed to form a line in the width direction at the upper end of the standing laminated glass. If the laminated glass is tilted in the width direction, the air space is formed. The air space can be collected so as to form an air reservoir at the corner of the laminated glass, but in order to do this manually, a plurality of workers are required and the working efficiency is lowered.

  The present invention has been made in view of such circumstances, and the problem to be solved is that by placing a laminated glass filled with a liquid resin, an air reservoir can be formed at the corner so that air can be easily vented. It is to provide a laminated glass air venting table, and to provide a laminated glass air venting method using the air venting table.

  In accordance with the above-described problems, the present invention provides a sequential or simultaneous two-way tilt of a primary tilt that tilts the work table on which the laminated glass filled with the liquid resin is tilted in one width direction and a secondary tilt that tilts in the front-rear direction. Conversely, the work table is tilted three-dimensionally by performing a sequential or simultaneous two-way tilt by a primary tilt that tilts the work table in one longitudinal direction and a secondary tilt that tilts in the width direction in one direction. An air reservoir that collects air is formed so that the air can be easily and reliably extracted and removed. In other words, the invention according to claim 1 is tilted in one direction in the width direction and one in the front-rear direction. Work table that can be tilted toward one direction of the diagonal line and tilted toward one side of the diagonal line, and can be freely tilted in three dimensions with the peak position at the rear end of the diagonal line. Be provided with is obtained by the air vent table laminated glass characterized by.

  In addition to the above, the invention described in claim 2 is configured so that each tilt of the two-way tilt can be reliably made with a simple structure as much as possible. Can be freely moved by operating a lifting device disposed between the raising and lowering frame and the work table in a pivotally supported state in which the work table can be rotated in the width direction with respect to the raising and lowering frame disposed below the work table. One tilt in the front-rear direction in the direction tilt is arranged between the base frame or the floor surface and the tilting frame in a pivotally supported state in which the tilting frame can be rotated in the front-rear direction with respect to the base frame disposed below the tilting frame. The laminated glass air venting table according to claim 1, which can be freely operated by operating the lifting device.

  In order to provide a method for venting laminated glass using the air venting table, the invention described in claim 3 is made by either sequentially tilting in the width direction and tilting in the front-rear direction or By using an air release table equipped with a work table that is tilted in one direction of the diagonal line by the two-way tilt at the same time and is free to perform three-dimensional tilt with the rear end of the diagonal line as a peak position, A laminated glass air venting method is characterized in that a resin-filled laminated glass is placed and tilted three-dimensionally to suck and remove an air reservoir formed at the corner of the laminated glass.

  The present invention uses each of these as the gist of the invention as means for solving the above problems.

  Since the present invention is configured as described above, the invention according to claim 1 is characterized in that the work table on which the laminated glass filled with the liquid resin is placed is tilted in one direction in the width direction and in one direction in the front-rear direction. The work table is tilted three-dimensionally by performing two-way tilt: primary tilt that tilts the work table in one of the longitudinal directions and secondary tilt that tilts in the width direction. Thus, an air bleed table for laminated glass can be provided in which air is collected at the corners of the laminated glass to form an air reservoir, and the air can be easily and reliably extracted and removed.

  In addition to the above, the invention described in claim 2 can reliably make each tilt in the two-direction tilt as simple as possible.

  According to the third aspect of the present invention, an air reservoir is formed at the corner of the laminated glass filled with the liquid resin on the work table by using the air venting table, and the air is easily and reliably made efficient. It is possible to provide a method for ventilating laminated glass that can be removed by suction well to eliminate product defects caused by air mixing.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. A is a laminated glass air vent table, and the air vent table A is tilted in one direction in the width direction and tilted in one direction in the front-rear direction. In this example, it is provided with a work table that can be tilted in one direction of a diagonal line and can freely tilt in a three-dimensional direction with the rear end of the diagonal line as a peak position by two-way tilting in the same direction or simultaneously. Thus, one tilt in the width direction in the above two-direction tilting is performed between the raising frame 2 and the work table 3 in a pivotally supported state in which the work table 3 can be rotated in the width direction with respect to the raising frame 2 arranged below the work table 3. Can be freely operated by operating the lifting / lowering device 22 disposed on the base frame 1 with respect to the base frame 1 disposed below the raising / lowering frame 2. There as those freely by operating the lifting device 11 which is disposed between these base frame 1 or the floor and raised or lowered the frame 2 by pivotally supporting state of the universal front-rear direction rotation of the credit frame 2.

  In other words, in this example, the air vent table A is supported on a base frame 1 that forms a horizontal support base by being installed on the floor surface, and is pivotally supported on the base frame 1 so as to be rotatable in the front-rear direction. An upper / lower frame 2 above the base frame 1, a work table 3 that is pivotally supported by the vertical frame 2 so as to be rotatable in the width direction, and the base frame 1 or the floor and the vertical frame 2. A raising / lowering device for a raising / lowering frame, which forms a tilting means in the front / rear direction that tilts by tilting the raising / lowering frame 2 with respect to the base frame 1 so as to be rotatable in the front / rear direction about the pivot position. 11, the work table 3 is interposed between the raising and lowering frame 2 and the work table 3, and the work table 3 is raised and lowered with respect to the raising and lowering frame 2 with the pivotal support position as a rotation center. For the work table 3 that tilts in the width direction to tilt The air vent table A includes, for example, the above-described tilting in the width direction as a primary tilt and the tilting in the front-rear direction as a secondary tilt, and the secondary table after the primary tilt or simultaneously with the primary tilt. The three-dimensional tilt of the work table 3 is made free by tilting in two directions.

  At this time, the pivotable pivotal support of the rising frame 2 of this example includes, for example, a pair of bearings in the widthwise direction protruding upward by being opposed to the both sides of the front end of the side frame of the base frame 1. The longitudinal axis of the rotary shaft 11 elongated in the width direction so as to be parallel to the front frame of the base frame 1 on a pair of bearings in the same width direction protruding downward at both ends of the lower surface of the front frame of the raising frame 2. This is done by rotatably supporting both end portions in both directions.

  Further, the pivotally supported pivot of the work table 3 according to the present embodiment includes, for example, a pair of front and rear bearings arranged to project downward in the middle of the width of the lower surface of the work table 3, particularly the central position, and corresponding positions. The pair of bearings in the front-rear direction, which are arranged to protrude upward on the upper surface of the fall frame 2, have a rotary shaft 21 elongated in the front-rear direction so as to be parallel to the work table 3, that is, the center line in the width direction of the fall frame 2. This is done by rotatably supporting front and rear end portions at both ends in the longitudinal direction.

  Each of the elevating devices 12 and 22 constituting the tilting means can be mechanically formed by appropriately combining mechanical elements, but in this example, the structure is as simple as possible. In order to achieve stable operation over a long period of time, for example, this is constituted by a cylinder operated by a hydraulic motor or an air compressor, respectively, the tilting frame 2 is tilted by the expansion and contraction of its piston rod, and the work table 3 is tilted.

  That is, the cylinder of this example can be rotated at its fixed end by using a clevis type having a clevis on both ends, a clevis on a rod, a rod clevis having a trunnion on a cylinder tube, or an intermediate trunnion type. Are interposed between the base frame 1 and the raising / lowering frame 2 and between the raising / lowering frame 2 and the work table 3.

  The cylinder of the raising and lowering device 12 for the raising and lowering frame is located at an intermediate position in the width direction between the base frame 1 and the raising frame 2, particularly at an intermediate position between the center frame and the rear position of the base frame 1 perpendicular to the rotation shaft 11. It is arranged between the lower frame and the intermediate horizontal frame in front of the tilting frame 2, and the tilting frame 2 is tilted up and down around the rotating shaft 11 at the front end while the cylinder swings back and forth by expansion and contraction of the cylinder rod. In this example, the cylinder has a connecting frame installed between the tip of the cylinder rod and the clevis, and the guide rod for driven is extended and driven from the lower end guide according to the expansion and contraction of the cylinder rod. 13 so that the tilting of the raising / lowering frame 2 can be performed as stably as possible.

  The raising / lowering angle of the raising / lowering frame 2 by the cylinder of the lifting / lowering device 11 is set so that, for example, the raising / lowering angle is raised from a horizontal state on the base frame 1 to a vertical position or a position of 80 to 90 degrees close thereto. A large glass glass 4 filled with a liquid resin is set on the work table 3 in a state where the work table 3 having the rising and lowering frame 2 in the lower position stands up at a predetermined angle. For example, by placing the laminated glass on the horizontal work table 3, the possibility of the laminated glass receiving an impact can be eliminated and the laminated glass placing work can be easily and safely performed. It is like that.

  Further, the cylinder of the lifting device 22 for the work table has the cylinder rod extending and retracting between the end side frame of the raising / lowering frame 2 and the end of the work table 3 in the width direction, in this example, between the front and rear intermediate positions. Are arranged so as to operate in the opposite direction, and the cylinders are respectively moved so that the work table 3 is raised at one end and the work table 3 is lowered at the same speed at the other end by reverse expansion and contraction of both ends of the cylinder rod. Similarly, the work table 3 can be tilted about the rotation shaft in the middle in the width direction while swinging back and forth. At this time, the cylinder of this example has one of the tilt frame 2 and the work table 3 in the width direction. It is assumed that a total of three places are arranged on both sides in the width direction of one front and rear center position and two other front and rear positions in the width direction.

  In this way, the air vent table A, which is capable of three-dimensional tilting by sequential or simultaneous two-way tilting, is used as a method for venting the laminated glass 4 using the same. The air reservoir formed at the corner of the laminated glass 4 is removed by suction by placing 4 and tilting three-dimensionally.

  That is, the work table 3 is formed with a glass receiving surface by a large number of rolling tools 31 such as rollers and casters on the upper surface thereof, and the laminated glass is floated and supported so that the laminated glass 4 can be easily placed and removed. A laminated glass 4 filled with a liquid resin is placed on the work table 3 and the air reservoir is sucked and removed.

  If this is explained in the method of manufacturing laminated glass 4, for example, a synthetic resin adhesive tape is fixed to the outer peripheral end surfaces of a pair of opposed glass panels that have been cleaned, and the release paper is left in a part of the outer peripheral end surface where the jig is inserted. Insert a resin injection jig to expand the glass panel, erect the glass panel, and inject a predetermined amount of liquid resin, for example, acrylic resin, according to the filling volume between the glass panels from the jig insertion position, The jig is removed and the remaining release paper is peeled off to close the jig insertion slot and form a semi-finished laminated glass 4. At this time, the liquid resin is injected in an upright state, and the pair of opposing glass panels are bent so as to swell in the front-rear direction under the weight of the resin, so that air enters between the glass panels in the resin-filled state. Since the air space generated by the difference between the volume and the liquid resin amount is formed, the laminated glass 4 of the semi-finished product containing air is then placed on the air vent table A and the air is vented.

That is, the air bleed table A is designed to perform the three-dimensional tilt of the work table 3 by performing tilting in one direction in the width direction and tilting in one direction in the front-rear direction in random order or by performing these tilts simultaneously. For example, when the work table 3 is tilted three-dimensionally after the semi-finished laminated glass 4 is placed with the work table 3 standing, the cylinder of the work table lifting device 22 is operated so that the work can be easily performed. The cylinder of the raising / lowering frame raising / lowering device 12 is actuated without causing the raising / lowering frame 2 to stand at a predetermined angle. The end portion of the laminated glass 4 is held by, for example, fixing the clip 33, and the laminated glass 4 of the semi-finished product is placed on the work table 3.

  Then, while holding the laminated glass 4, the cylinder of the raising / lowering frame lifting / lowering device 12 on the air vent table A is operated to fall the raising / lowering frame 2, for example, the work table 3 is tilted at an angle of about 1 to 20 degrees. In this state, the cylinder of the lifting device 22 for the work table is operated so that the work table 3 is set at an angle of, for example, about 1 to 20 degrees with respect to the tilting frame 2. Performing sequential two-way tilting by two-stage movement that tilts secondarily in the width direction, and setting the work table 3 to the peak position at the rear end of the first-order tilting in the width direction in this example, What is necessary is just to incline three-dimensionally in the state which turned to the diagonal direction which makes the descending front end the lowest.

  The laminated glass of the semi-finished product placed on the work table 3 is three-dimensionally inclined in accordance with the three-dimensional inclination of the work table 3 so that the air that has entered the laminated glass 4 together with the injected resin is 3 gathers at the corner on the peak position side and forms an air pool at the corner. Therefore, the laminated glass 4 may be vented by sucking and removing the air pool. The suction removal of the air reservoir is performed, for example, by inserting an air suction needle into the adhesive tape on the outer peripheral end surface of the glass panel and performing vacuum suction.

  The semi-finished laminated glass 4 that has been air-bleeded may then be cured between glass panels by a predetermined curing means such as heat curing or ultraviolet curing to form a finished product. can do.

  In the figure, 14 is an upright seat with a cushion for receiving and supporting the back of the upright frame 2 arranged at two corners of the rear end of the base frame 1, and 23 is a work table 3 arranged at four corners of the upright frame 2. A buffering spring 32 for receiving and supporting the back surface is shown as a positioning stopper for placing the laminated glass disposed at an appropriate position such as the width direction end of the work table 3.

  Although the illustrated example is as described above, the lifting device that tilts one side in the width direction or one in the front-back direction is performed by a mechanical mechanism by a combination of machine elements, and the three-dimensional tilt of the work table is performed in the width direction. The tilting toward one side is the primary tilting and the tilting toward the one side in the front-rear direction is the secondary tilting so that the two-way tilting is performed. Tilt the tilting frame to make it horizontal once, and then tilt one side in the width direction or one in the previous direction from the horizontal state in random order, and simultaneously tilt one side in the width direction and one in the front-rear direction at the same time. In carrying out the present invention, the above-mentioned air vent table, work table, raising / lowering frame used as necessary, base frame Various shapes, structures, materials, usage methods, usage procedures, relationships, additions to these, etc., as long as they do not contradict the gist of the invention.
