JPH06269721A - Device for sticking work for windowpane of rolling stock - Google Patents

Abstract

PURPOSE:To provide a device for fitting windowpanes for rolling stockswhere the function of equipment is simplified and equipment cost is made low and working time is shortened by equipping the device with a truck, a robot for work, a sealant applicator, a sealant forming device and a pressing device. CONSTITUTION:In a device for fitting windowpanes of rolling stocks, first a truck 10 is moved, and the sticking of the circumference of a window W, the cleaning of parts to be worked for sealing and the pasting of a masking tape around the parts to be worked are done by a man power or a robot 11 and after the above work is finished, work, such as the coating of a sealant and the forming of the sealant is done by a robot 11. In doing fitting work, while a windowpane is pressed toward a seat by a pressing device, the sealant is applied by a sealant applicator 30 and the application is made by moving an arm while the sealant is formed by a sealant forming device. Consequently, since both the applying and the forming of the sealant are done substantially at the same time, a sealant of two-pack mixing type is also applied and since the windowpane is kept pressed, it is fixed as prescribed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a working device suitable for adhering (sealing agent coating, filling, shaping) a window glass of a railway vehicle.

[0002]

2. Description of the Related Art Various methods have been proposed for automating and labor saving by using a robot for outfitting and assembling work. For example, there is a process of assembling and adhering window glass on the front and back of automobiles. This is because the vehicle body to which the window glass is assembled is moved by a conveyor or the like for each individual work station where a work robot is arranged.
Window glass cleaning, window glass primer application, adhesion
Work steps such as application of sealant and attachment of glass are performed. (Roboto No.78 P15 ~ P19 Robotic unmanned bonding process of wind glass)

[0003]

However, since the above-mentioned prior art is a system in which the vehicle body is moved for each individual work station, the length of the equipment line becomes extremely large when applied to a railway vehicle. That is, the length of the car body is several times larger than that of an automobile, and many work stations are required.
The length (size) is about 20 times as large as that of a car, because it requires an option. In addition to the enlargement of the equipment line, since an expensive work robot is arranged for each work station, the equipment cost becomes extremely large.

Further, since the car body is moved for each individual work station (work process), the length is 2 in the case of a railway vehicle.
It is extremely large with a mass of 0 to 26 m and a mass of 20 to 50 tons, a long moving distance, and a large force required for moving, so that the working time required for moving becomes extremely long. In addition, the sealant used to bond the window glass of the railroad vehicle is a two-liquid mixed type (a main agent and a curing agent are mixed and used, and cured by a thermal reaction), so that the temperature is high. When using for a period, see
It takes less time to cure the adhesive.

Further, in a railroad vehicle, glass is fitted to the opening of the structure, positioned through packing, and attached by a presser foot. However, since the accuracy of the opening of the structure is not ensured, it is necessary to align the glass for each opening, and as shown in the above-mentioned known example, automation of applying the sealant in advance cannot be performed. Therefore, the coating and filling of the sealing agent between the glass and the edge of the opening of the structure depended on manual work. It is an object of the present invention to omit the function of the equipment, reduce the equipment cost, and shorten the working time.

SUMMARY OF THE INVENTION The present invention is directed to a traveling carriage, a work robot installed on the carriage, a sealant applicator installed on an arm at the tip of the robot, and a sealant applicator. A window glass mounting device for a railroad vehicle, which is located at the rear and includes a sealing agent molding device installed on the arm and a pressing device installed on the arm and having a roller for pressing the window glass, is configured. It is characterized by

It is characterized by comprising a seal shaping tool attached to a working tool unit (sealant applying dispenser) and performing shaping at the same time as applying and filling the seal.

[0008]

The vehicle body of the railway vehicle is loaded into the station of the equipment for assembling and assembling by the towing vehicle or the conveyor, and the equipment for assembling the windows and doors and the assembling work are performed. When the vehicle body is loaded, the rigging and assembling equipment dolly moves to the respective window positions, and the robot on the dolly carries out the installation of the windows in cooperation with people.

Then, as in the case described above, the dolly moves, and the bonding of the periphery of the window, the cleaning of the portion to be sealed for sealing, and the attachment of the masking tape around the portion to be coated are performed by humans or robots. After the work is completed, the robot performs the work such as applying and shaping the sealant.

The mounting operation is performed by pressing the window glass toward the seat with the pressing device, applying the sealant, and moving the arm while molding it with the molding device. According to this, since the sealing agent is applied and molded substantially at the same time,
It can also be applied to a two-liquid mixed type sealant. Further, since the window glass is pressed down, the window glass can be fixed in a predetermined manner.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to one embodiment of FIGS. In FIG. 1, A is the structure of the railway vehicle,
w is the window. Reference numeral B is a railroad vehicle device for performing window sealing work. The device B has a work carriage 11 and a robot controller 12 mounted on a traveling carriage 10. A sealant applicator 30 is installed at the tip of the robot arm.

With the working device thus constructed, the traveling carriage 10 moves around the vehicle body A and advances the seal of the fixed window glass. A measurement camera 13 is provided in the robot arm portion, and when the carriage 10 comes near the target position of the window w, the carriage 10 stops and the visual field of the measurement camera 13 is processed by the image processing device 16. As a result, the position of the coating device 30 can be detected and the regular position can be obtained.

The structure of the coating device 30 will be described with reference to FIGS. On the back surface of the outer plate A1 of the structure A, there is a seat W2 for attaching the window glass W1. The sealant S is applied to the corner between the window glass W1 and the outer plate A1.

The coating device 30 is a sealant coating device 31.
And a molding device 35 including a molding spatula 36 and a window glass W
It is composed of a pressing device 40 that presses 1 toward the inside of the vehicle. The coating device 31 supplies a fixed amount of the sealing agent S. Molding device 35
Is located rearward in the moving direction of the coating device 30, and the spatula 36 for shaping is made of a relatively soft material. The holding device 40 has a roller 41 rolling on the window glass w1, and is elastically supported by a spring 42. The pressing device 45 elastically supports a roller 46 rolling on the outer plate A1 by a spring 47.

The outfitting work of the body of a railroad vehicle is mainly inside the body, and an operator often goes in and out of the body, and at that time, the body shakes. In this case, springs 42 and 47 are attached to prevent the collision of the tool body and the window glass. When the application of the sealant on one window glass is completed,
The carriage 10 moves to the position of the next window glass.

[0016]

According to the present invention, the operation can be performed even with a two-liquid mixed sealant.
