Abstract

(57) [Summary] [Purpose] To shorten the length of the conveyor line for electrodeposition coating. [Construction] The car body B is conveyed by a conveyor 13 while sequentially passing through a plurality of processing tanks 11 and 12. In the electrodeposition tank 12 of the processing tanks 11 and 12, an electrode plate 14 having a distance smaller than the length L of the car body B is provided. By the attitude changing means, the length direction of the car body B is oriented in the transport direction within the electrodeposition tank 12
In the processing tanks 11 other than the above, the posture of the vehicle body B being conveyed by the conveyor 13 is changed so that the width direction of the vehicle body B is directed to the conveyance direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a processing device for electrodeposition of a car body.

[0002]

[Prior art]

 As a conventional apparatus of this type, a plurality of processing tanks, at least one of which is an electrodeposition tank, and a vehicle body placed so that the length direction of the vehicle body faces the transport direction, and the plurality of processing tanks are sequentially passed through However, it is known that the vehicle is equipped with a conveyor for transporting the car body, and the electrode plates are provided in the electrodeposition tank at intervals smaller than the length of the car body.

[0003]

[Problems to be solved by the device]

 In the above equipment, if the length of the conveyor transportation line is shortened, it is necessary to reduce the pitch of the car body conveyed by the conveyor, but it is impossible to make the pitch smaller than the length of the car body. Therefore, there was a limit to shortening the length of the conveyor transportation line.

An object of the present invention is to provide a vehicle body processing apparatus capable of shortening the length of a conveyor transportation line.

[0005]

[Means for Solving the Problems]

 A vehicle body processing apparatus according to the present invention is an apparatus for processing a vehicle body having a length and a width, such as electrodeposition, and includes a plurality of processing tanks, at least one of which is an electrodeposition tank, and a plurality of processing tanks. The car body is equipped with a conveyor that conveys the car body while sequentially passing through it, and in the car body processing equipment, the electrode plates are provided in the electrodeposition tank at intervals narrower than the length of the car body. There is a means to change the posture of the car body being conveyed by the conveyor so that the length direction of the car body is oriented in the transport direction and the width direction of the car body is oriented in the transport direction in processing tanks other than the electrodeposition tank. It is characterized by that.

[0006]

[Action]

 In the car body processing apparatus according to the present invention, the conveyor body is arranged so that the length direction of the car body is oriented in the transport direction inside the electrodeposition tank, and the width direction of the car body is oriented in the transport direction inside the processing tanks other than the electrodeposition tank. Since there is a means to change the posture of the car body being conveyed, the pitch of the car body that is conveyed by the conveyor will change when the car body is conveyed with the width direction of the car body facing the conveyance direction. It can be smaller than the length of the car body.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the following description, “front and back” refers to the side indicated by an arrow in FIGS. 1 and 2 as the front (left side of FIG. 1) and the opposite side as the rear, and “left and right” refers to the left and right sides toward the front. Left and right (upper and lower in Fig. 2).

Referring to FIG. 1, a vehicle body treatment apparatus includes a plurality of treatment tanks including a pretreatment tank 11 and an electrodeposition tank 12 disposed in front of the pretreatment tank 11, and a plurality of treatment tanks 11 and 12. It is provided with a conveyor 13 for transporting the car body B while sequentially passing through.

The car body B has a length L and a width W like a passenger car.

The pretreatment tank 11 is for cleaning the vehicle body B with water, degreasing, surface conditioning, and the like. Referring to FIG. 3, electrode plates 14 are attached to opposite side surfaces of the electrodeposition tank 12 so as to face each other. The distance between the electrode plates 14 is larger than the width W of the car body B but smaller than the length L. As the distance between the electrode plates 14 increases, the distance from the electrode plates 14 to the center of the car body B increases. In that case, good electrodeposition cannot be performed. Therefore, it is preferable that the distance between the electrode plates 14 is as small as possible.

The conveyor 13 has a rail 21 extending sequentially over a plurality of processing tanks 11 and 12, a plurality of pairs of trolleys 22 and 23 that form a pair before and after traveling along the rail 21, and a front and a rear. It consists of a carrier 24 suspended from a pair of trolleys 22 and 23.

Referring to FIG. 2, the rail 21 has a branch rail 25 that is branched before the pretreatment tank 11 and is joined at a position after the pretreatment tank 11.

The vehicle body B is conveyed up to the front side of the pretreatment tank 11 while being placed on the carrier 24 with its length direction oriented in the conveyance direction. When the trolleys 22 and 23 before and after the carrier 24 is suspended approach the branch rail 25, the front trolley 22 is moved along one side of the branch rail 25 and the rear trolley 23 is moved along the other side of the branch rail 25. As a result, the carrier 24 is changed by 90 degrees from the previous direction, the direction of the car body B 1 mounted on the carrier 24 is also changed by 90 degrees, and the car body B is oriented in the width direction.

When the front and rear trolleys 22 and 23 pass the branch rail 25, the carrier 24 returns to its original orientation, and the vehicle body B has its length direction oriented in the transport direction. Then, the vehicle body B in this direction is carried into the electrodeposition tank 12, and the electrode plate 14 having an appropriate width is subjected to the electrodeposition process.

[0015]

[Effect of device]

 According to this invention, when the vehicle body is conveyed with the width direction of the vehicle body facing the conveying direction, the pitch of the vehicle body conveyed by the conveyor can be made smaller than the length of the vehicle body. Therefore, the length of the conveyor transportation line can be shortened.
