  FIG. 12 is a partial cross-sectional view of a window glass coated with an adhesive by the technique of Patent Document 1, and a black coating layer 112 that hides the bonding portion with the vehicle body is provided on the rear surface of the peripheral edge of the window glass 111 with a predetermined width W1. The dam rubber 113 is bonded to the center of the coating layer 112, the primer layer 114 is applied to the area of the width W2 outside the dam rubber 113, and the adhesive layer 115 is further applied to the upper surface thereof.

  By the way, in order to ensure a predetermined sealing performance, the adhesive layer 115 has a width W2 so that the adhesive does not protrude to the outside of the window glass 111 in the region of the limited width W2 outside the dam rubber 113. It is necessary to apply with a small width. Moreover, in order to ensure a predetermined sealing performance, it is necessary to keep the cross-sectional shape of the adhesive constant.

However, since the gun 102 according to the technique of Patent Document 1 includes the chevron discharge port 103, the adhesive application trajectory may deviate from the direction of the chevron discharge port 103 during application of the adhesive. There is a possibility that it cannot be applied with a smaller width.
There is a demand for an adhesive application device that can keep the application width smaller and keep the cross-sectional shape of the adhesive constant.

  It is an object of the present invention to provide an adhesive application device that can keep the adhesive application width small and keep the cross-sectional shape of the adhesive constant.

The invention according to claim 1 is an adhesive application device that discharges an adhesive from a cylindrical gun.

3 is a diagram for explaining the configuration of the primer supply device according to the present invention, and FIG. 4 is a sectional view taken along line 4-4 of FIG. Hereinafter, description will be made with reference to FIGS. 3 and 4.
The primer supply device 32 that supplies the primer PL as a viscous liquid includes a primer container 36 that stores the primer PL, and a base 37 inserted into the primer container 36 and the tip 38 is extended to the application location, so that it can be elastically deformed. A tube 33, a primer gun 13 that is detachably attached to the tip 38 of the tube 33, and a tube pump mechanism 39 provided in the middle of the tube 33.

  The primer gun 13 includes a plug-shaped main body 41, a tube 33 inserted from above into a hole 42 opened in the center of the main body 41, and an application portion 44 that is detachably attached to the main body 41 integrally with a felt material 43 from below. The main body 41 is inserted from below into a fixing hole 45 opened in the distal end portion 29a of the middle transverse beam 29 and fixed with a nut 46 from above. The distal end 38 of the tube 33 was brought into contact with the felt material 43. In the figure, 47 is a lid of the primer container 36, and 48 is a holding member for holding the primer container 36.

The tube pump mechanism 39 includes a body portion 51 and a drive arm 52 that is rotatably provided at the center of the body portion 51. The body portion 51 includes a circular inner wall 53 that extends along the tube 33 and a holder portion 54 that is disposed below the inner wall and holds the tube 33.
The tube pump mechanism 39 is provided with a motor 56 for driving the central shaft 55, and the motor 56 is fixed to the body portion 51 by a bracket 49 and a bolt 50 for fixing the bracket 49.

  The drive arm 52 includes a central shaft 55, arm members 57 extending from the central shaft 55 in three directions (... Indicate a plurality, the same applies hereinafter), and the arm members 57. The pulley 33 is rotatably attached to the inner wall 53 and handles the tube 33 between the inner wall 53 and the tube 33 along the inner wall 53 and held by the holder portion 54.

FIG. 5 is a flowchart for explaining the method of maintaining the primer supply apparatus according to the present invention, and will be described with reference to FIGS. STXX indicates a step number.
ST01: (Timer reset step): The timer is reset after the tube 33 is replaced.
ST02: (Limit value determining step): In order to determine the limit value, the operation of supplying the primer PL is performed, the clogging state of the tube 33 is checked, and the time limit value indicating that the clogging amount has reached the allowable limit ( T) is determined.

The limit value (T) varies depending on the operating conditions of the primer gun 13. For example, when the primer gun 13 is operated for 24 hours, the flow of the primer PL in the tube is performed relatively smoothly, and therefore the limit value (T) is longer than that when the primer gun 13 is operated for 8 hours per day. Set to value. In the case of being movable for 8 hours, the flow of the primer PL stops for 16 hours, so the primer PL in the tube 33 tends to harden and is set to a shorter value.
In this embodiment, the characteristic of the limit value is time (t). However, the flow rate of the primer PL may be used instead of the time.

ST03: (Primer supply operation step): The tube pump mechanism 39 is moved to supply the primer PL to the primer gun 13.
ST04: (Tube replacement time determination step): It is determined whether the limit value (T) determined in the limit value determination step has been reached.

ST05: (Tube replacement step): When the limit value (T) is reached, the primer supply device 32 is stopped and the tube 33 is replaced with a new tube.
The tube 33 may be replaced with a new tube before reaching the limit value (T) determined in the limit value determining step.

With the above-described method for maintaining the primer supply device, the problem that the tube 33 is clogged with the primer PL can be solved. Since clogging of the tube 33 is eliminated, the downtime of the primer supply device 32 can be minimized, and the probability (movability) that the primer supply device 32 can be operated when necessary can be increased. .
The movable rate (JIS Z8141) is the probability that the equipment can be operated when needed.

  FIG. 6 is a side view for explaining an adhesive application device according to the present invention. An adhesive application device 61 for discharging an adhesive 79 to the peripheral edge of glass stands a column member 63 vertically on the ground surface 62. An arm 64 is horizontally extended from the upper end 63a of the member 63, and a gun tip 65 formed at the tip of a cylinder is placed on the upper surface 64a of the arm 64 facing downward.

  With reference to FIGS. 1-6, the glass mounting apparatus 10 for vehicles which concerns on this invention degreases the peripheral part Ga of the glass G, apply | coats primer PL to the peripheral part Ga which performed this process, This primer It can be said that the apparatus can perform a series of operations for attaching the glass G to a predetermined position of the vehicle after the adhesive is applied on the top.

FIG. 7 is a sectional view and an operation diagram of the main part of FIG.
In (a), the adhesive application device 61 includes a storage portion 67 that also serves as a main body, a cylindrical gun 69 that is disposed in the storage portion 67 in a vertical direction and is rotatably provided via a bearing portion 68. An encoder 71 that detects the rotation angle of the gun 69 and a gun rotation means 73 that rotates the gun 69 in a predetermined direction via gears 72a and 72b are provided. In this embodiment, the gun rotating means 73 is a servo motor, but an electric motor, an air motor, a hydraulic motor or the like may be used.

  The gun tip 65 of the cylinder 74 constituting the gun 69 is provided with one notch 75, and a controller 76 for operating the gun rotation means 73 so that the notch 75 matches the application locus. . Reference numeral 77 denotes an application locus detection sensor.

  (B) is a cross-sectional view taken along the line bb of (a), in which the glass G held by the second robot (reference numeral 16 in FIG. 1) is moved in the direction of arrow D, and the peripheral edge Ga of the glass G is predetermined. The position indicates that an adhesive having a small coating width and a certain width can be applied.

  (C) is a view showing a cross section of glass coated with an adhesive, and a cylinder 74 having a notch 75 at the tip is operated so that the gun rotating means 73 is operated so that the notch 75 matches the application locus. The application trajectory of the agent and the orientation of the notch 75 are not shifted, and the adhesive 79 can be applied with a small width and a constant cross-sectional shape.

  If the application locus of the adhesive 79 and the orientation of the notch 75 are deviated, it is difficult to keep the cross-sectional shape of the adhesive 79 constant, and the adhesive 79 is applied to the peripheral edge Ga of the glass G having a limited width W. It is difficult to apply with a small width b.

  In this regard, in the present invention, since the gun rotation means 73 is operated so that the notch 75 matches the application locus, the application width b can be reduced and the cross-sectional shape of the adhesive 79 is kept constant. be able to. If the shape of the notch 75 is a triangular shape that is small in the width direction and high in the vertical direction, the cross-sectional shape of the adhesive 79 can be made small in the width direction. Since the cross-sectional shape of the adhesive 79 can be reduced in the width direction, the application width b of the adhesive 79 can be reduced. If the coating width b is reduced, the adhesive can be applied to a more accurate position of the peripheral edge Ga of the glass G, which has a large constraint on the coating space.

  By the way, the adhesive 79 is applied at a height H so as to be higher than the height h of the dam rubber 81 in the region of the width W outside the dam rubber 81 in order to ensure a predetermined sealing performance. However, since the outer width W of the dam rubber 81 is limited, if the application width b of the adhesive 79 is increased, the adhesive 79 may protrude outside the window glass G.

  If the application width b of the adhesive 79 can be reduced, the adhesive 79 can be made difficult to protrude outside the window glass G, and if the application height H of the adhesive 79 can be increased, less adhesive can be obtained. This is preferable because a predetermined sealing performance can be secured.

  Conventionally, in the case where the gun 74 of the cylinder 74 serving as the discharge port for the adhesive 79 has the notch 75, the notch 75 is not necessarily moved so as to match the application locus. In some cases, the cross-sectional shape could not be kept constant, for example, the coating width was widened and the coating height was lowered. In order to cope with this, when the adhesive is discharged so as to obtain a predetermined coating height, an excessive amount of the adhesive is applied, and there is a problem that a work such as wiping is required in a subsequent process.

  In this regard, in the present invention, the adhesive 79 having a preferable cross-sectional shape can be applied by appropriately setting the shape of the notch 75 and directing the notch 75 so that the notch 75 matches the application locus. Therefore, by appropriately managing the discharge amount, the application width b of the adhesive 79 formed perpendicular to the application direction can be reduced, and the adhesive 79 having a preferable cross-sectional shape can be applied.

ST19: (Glass transfer process): The first robot 15 transfers the glass G to the glass relay table 23a or the glass relay table 23b that also serves as the glass drying tables 82a and 82b. At this time, the 1st robot 15 is mounted in the glass relay stand of the glass relay stand 23a or the glass relay stand 23b in which the glass G is not mounted.

FIG. 9 is a flowchart for explaining the operation of the second robot (RB2) provided in the glass mounting device for a vehicle according to the present invention, which will be described with reference to FIGS. STxx is a step number.
ST21: (Glass positioning step): The glass G is aligned by the glass positioning device 21a or the glass positioning device 21b provided in the glass relay stands 23a and 23b. In detail, the positioning plate 86 ... provided in the glass positioning device 21a or the glass positioning device 21b is pushed, and the glass G is aligned.

ST25: (Glass transfer process): The second robot 16 moves the glass G coated with the adhesive to a predetermined position of the vehicle 11 to face the vehicle.

  As explained in each of the above steps, the conveyance of the glass G and the movement of the glass G in the process are continuously performed by the first robot 15, and the conveyance of the glass G and the movement of the glass G in the process are second. The robot 16 is continuously operated.

  Further, the first robot 15 collectively moves the glass G during the degreasing process and the primer process, and the second robot 16 uses the glass G before and after the adhesive application process and the adhesive application process. Was carried out in a batch.

  In the present embodiment, the drying table 82 is merely disposed at the position 19 where the operation region 17 of the first robot 15 and the operation region 18 of the second robot 16 overlap each other, so that the interference between the two robots 15 and 16 is prevented. The operating rate of the robots 15 and 16 can be further increased, and the robots 15 and 16 can be used effectively.

  Here, if the operation region 17 of the first robot 15 and the operation region 18 of the second robot 16 are arranged so as not to overlap, each robot 15, 16 can be operated completely independently, and further The robot operation rate can be improved.

FIG. 10 is a timing chart of the glass mounting device for a vehicle according to the present invention, and will be described with reference to FIGS.
The glass relay stand 21 includes one and the other two glass relay stands 23a and 23b. The glass relay stand 23a and 23b receives the glass G from the first robot 15 to the second robot 16. It is configured to pass.
In the figure, above each job, a robot that sucks and holds the glass G as a work, and a glass relay stand are described.

  First, the first robot 15 places the glass G on the glass relay table 23a, aligns it with the glass positioning device 21a, adsorbs the glass G with the adsorption unit 83, and applies it to the degreasing liquid gun 12 and the primer gun 13. Apply each liquid. After application, the primer PL is dried again by placing it on the glass relay table 23a. After the predetermined primer drying time has elapsed, the second robot 16 adsorbs the glass G by the adsorbing portion 83, faces the adhesive gun 14, applies the adhesive, and transfers it to a predetermined position of the vehicle 11.

  While the first robot 15 applies a primer or the like, places it on the glass relay table 23a, and dries the primer applied to the glass G, the first robot 15 applies another glass G from the stocker 84. After taking out and placing on the glass relay table 23b and aligning with the glass positioning device 21b, the glass G is adsorbed by the adsorbing unit 83 and applied to the degreasing liquid gun 12 and the primer gun 13 to apply each liquid. After the application, the primer is again placed on the glass relay table 23b and dried. In this way, three types of liquids are applied to the glass G, and the glass G to which the adhesive has been applied is transferred to the vehicle 11.

  Since the first robot 15 places the glass G coated with the primer on one of the two glass relay stands 23a and 23b, the second robot 16 is placed on the other side. It is possible to perform a series of operations in which the glass G placed on the relay stand is sucked and held to face the adhesive gun 14, the glass is moved, the adhesive is applied, and the vehicle 11 is set.

  That is, since the glass G is delivered using the two glass relay stands 23a and 23b, the first robot 15 and the second robot 16 are simultaneously connected, for example, for the times L1 and L2 shown in the figure. It can be operated.

  Since the first and second robots 15 and 16 can operate at the same time, it is possible to greatly shorten the robot stop time due to so-called work waiting, in which one robot waits for the other robot. Therefore, the robot stop time is significantly shortened, and the operation rate of the robot can be increased.

In addition, since the first and second robots 15 and 16 can operate simultaneously, an increase in cycle time can be suppressed and production efficiency can be increased.
In this embodiment, the number of glass relay stands is two, but may be three or four, and can be set to an arbitrary number in consideration of the area of the application area, the cycle time, and the like.

The operation of the vehicle glass mounting device described above will be described next.
First, as shown in FIG. 1, the vehicle glass mounting device 10 includes a degreasing liquid gun 12, a primer gun 13 and an adhesive gun 14 that are fixed to the ground and the like, and adsorbs and holds the glass G to the degreasing liquid gun 12.

And a second robot 16 that moves the vehicle to a predetermined position on the line.

  The first robot 15 conveys the glass G, moves the glass G while holding it, applies a degreasing liquid, and then applies a primer. Then, the glass G taken over from the first robot 15 was transported by the second robot 16 and moved while holding the glass G to apply the adhesive.

  In addition to transporting the glass G, the robots 15 and 16 are used to move the glass G during liquid application. Therefore, the operating rate of the robots 15 and 16 can be increased, and the robots 15 and 16 can be used more effectively. can do.

  In addition, in a glass coating line having a process of applying a degreasing liquid, a primer, and an adhesive to glass, equipment for placing glass during work becomes unnecessary, and the equipment cost can be greatly reduced. . Furthermore, when applying each liquid to the glass, a positioning jig is not required, so that the area of the glass application area, which is a space necessary for applying the adhesive to the glass, can be greatly reduced.

  Second, as shown in FIG. 3, the primer supply device 32 is provided with an elastically deformable tube 33 that extends between the primer container 36 and the application gun 69. A tube pump mechanism 39 is interposed. Since the tube 33 is detachably provided on the primer supply device 32, the tube 33 can be easily replaced.

  Since the tube 33 can be easily replaced, in order to avoid clogging of the tube 33 due to the primer PL, the cleaning in the tube 33 and the cleaning of the pump, which are necessary every predetermined period, can be abolished. The time required for replacing the tube 33 can be significantly shorter than the time required for cleaning the inside of the tube and the pump without replacing the tube. Time can be shortened. By performing the maintenance time of the primer supply device 32 in a short time, the operability of the primer supply device 32 can be increased.

  Thirdly, as shown in FIG. 7, the adhesive application device 61 includes a gun rotating means 73 that rotates the gun 69, and one notch 75 provided at the tip 38 of the cylinder 74 that constitutes the gun 69. And a control unit 76 for operating the gun rotating means 73 so that the notch 75 matches the application locus.

  Since the gun rotating means 73 is operated so that the notch 75 matches the application trajectory of the cylinder 74 provided with the notch 75 at the tip 38, the application locus of the adhesive 79 and the orientation of the notch 75 are not shifted. The adhesive 79 can be applied with a small width b and the cross-sectional shape of the adhesive 79 being kept constant.

Gun rotating means that rotates in the direction, an encoder that is provided in the housing and detects the rotation angle of the gun, and is provided on the tip side wall of a cylinder that constitutes the gun and has a circular cross section with a constant horizontal cross section. A notch part , and a control part for operating the gun rotating means so as to reduce the application width of the adhesive by matching the notch part with the application locus and to keep the cross-sectional shape of the adhesive constant. Consists of
As the cut section matching the application locus, and to rotate the gun rotating means, the pre-Symbol adhesive application device, mounted on arms extending horizontally, was attracted to and held by the robot at the tip of the gun The workpiece is applied, and the robot is moved three-dimensionally to be applied with a height (H) (h <H) higher than the height (h) of the dam rubber provided on the workpiece, and the adhesive is applied. adhesives coating device characterized in that so as to apply the adhesive to have a preferred cross-sectional shape by reducing the width.
