Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to constituent members of an automobile body, such as a floor, a roof, and a side panel, in a predetermined positional relationship on a set carriage at a set station at the beginning of a body assembly line. The present invention relates to a setting device for setting.

(Prior Art) Conventionally, according to JP-A-59-114173, a reciprocating set carriage is provided between a set station and a connecting station in front of the set station, and a floor, a roof, and a side, which are vehicle body constituent members, at the set station. Welding jigs that set the panels on the set trolley in a predetermined positional relationship with the floor, roof, and site panel setting devices, convey these members to the joining station in the set state, and arrange them on both sides of the joining station. Accordingly, an assembly line for an automobile body is known in which these members are welded and joined to assemble an automobile body.

In this configuration, the side panel setting device includes a pair of left and right drop lifters for receiving and lowering a pair of left and right side panels carried by a hanger from a hanger above the set station, and the drop fritters. Each side panel is received from and set on the set trolley. It is composed of a pair of left and right set jigs that can move back and forth in the lateral direction, and the roof set device is mounted on the guide frame provided on the side of the set station. , A roof setting jig is hung at one end and a horizontally long movable frame is supported movably in the horizontal direction toward the set station, and the set carriage is returned to the set station. Then, set the floor on the set trolley with the floor setting device, and then with each drop lifter of the side panel setting device. Each side panel received by the set jig is set on the set carriage so that its lower edge is joined to the side edge of the floor by each set jig, and the jig of the roof setting device is moved by moving the movable frame. The roof, which is preliminarily held on the side of the set station by the jig by entering the set station, is set between the roof side rails of the left and right side panels.

(Problems to be Solved by the Invention) In the above, the roof setting jig, that is, the roof setting jig, is set so that the roof side setting jig does not interfere with the side panel setting jig arranged on the side of the setting station. The movable frame to be hung must be moved laterally at a position higher than the set jig for the side panel, so the guide frame is composed of a longitudinally elongated gate frame and can be moved to the beam part above it. The frame is supported, and the supporting span of the other end of the movable frame with respect to the beam is taken longer in order to increase the support rigidity of the movable frame that suspends the set jig, which is a heavy object, in a cantilever state at one end. It is necessary to increase the size of the entire roof setting device including the guide frame, and it is necessary to secure a large space for arranging the roof setting device on the side of the setting station, resulting in space efficiency. become worse.

Further, conventionally, a dashboard upper and a rear tray mounted between the left and right side panels are manually set at a set station, which is a problem in improving productivity.

In view of the above points, the first object of the present invention is to narrow the side space of the set station so as to improve the space efficiency. Further, in addition to the roof, the dashboard upper and the rear tray are automatically set. The second purpose is to obtain.

(Means for Solving the Problem) In order to achieve the first object, in the invention of claim 1, the constituent members of the vehicle body such as a floor, a roof, and a side panel are set at a set station at the starting end of the vehicle body assembly line. A set device for setting a predetermined positional relationship on a trolley, which receives a floor setting device for loading and setting a floor on the set trolley, and a pair of left and right side panels loaded by a hanger above a set station. A pair of left and right side panel setting devices that are set on a set carriage, and a roof setting device that sets a roof between roof side rails of the left and right side panels set on the set carriage, each side panel The set device is provided with a jig that positions and holds the side panel on the elevating frame so that it can move back and forth in the horizontal direction. By receiving the side panel from the hanger by retracting the jig in the horizontal direction at the upper moving position of each elevating frame and moving the jig in the lateral direction at the lower moving position of each elevating frame. It is configured to set a side panel on a set trolley, and the roof setting device is arranged in the lateral center above the set station, and the roof can be placed on the side of the set station. A loading device provided with a set frame that can move back and forth laterally toward the set station is arranged so that the roof can be received by the roof set device through the set frame. In this case, as in the third aspect of the present invention, a machine frame provided above the side portion of the setting station is provided with a vertically elevating vertically elevating bar, and the elevating bar has an elevating frame of the side panel setting device. It is desirable to support the so that it can move up and down. Further, in order to achieve the second object, in the second aspect of the present invention, the setting device for the dashboard upper and the rear tray is provided at the center of the upper side of the setting station in the lateral direction, in front of and behind the roof setting device. And the dashboard upper portion and the rear tray receiving portion are provided in front of and behind the roof receiving portion for mounting the roof on the set frame.

(Operation) The operation of the present invention will be described based on the invention of claim 2.

After sending out the set carriage from the set station, raise the jig of each side panel setting device to receive the side panel from the hanger, and set frame in which the roof, dashboard upper and rear tray are placed in advance. Of the roof, the dashboard upper, and the rear tray, respectively, to receive the roof, the dashboard upper, and the rear tray, and then withdraw the set frame to the side of the set station. After that, the jig is lowered.

Then, when the set carriage is moved back to the set station, the floor is loaded and set on the set carriage by the floor setting device, and then the dashboard upper and the rear tray are lowered to a fixed position by the set device for the set, and then the aforesaid cure is performed. Move the tool laterally inward and set the left and right side panels so that the floor, dashboard upper, and rear tray are sandwiched from both sides, and finally set them on the set trolley, and finally operate the roof setting device to move the roof side of the left and right side panels. Insert the roof between the rails from above and set it, then send out the set truck from the set station, and
Complete the set work once.

According to the present invention, since the side panel is set on the set carriage while the side panel is held by the jig that is moved up and down, the side panel for the stationary type is installed on the side of the set station as in the conventional case. It is not necessary to provide a set jig, and if the jig is raised, there will be no obstacles on the side of the set station, so the set frame can be moved back and forth at a relatively low level in the set station, and the set frame is the roof. It suffices to provide a receiving part for mounting the etc., and it is lighter than a setting jig equipped with a clamper etc., and eventually the loading device can be made compact and the side space of the setting station can be narrowed. It will be possible.

By the way, in order to avoid interference between a supporting member such as a support for vertically moving the elevating frame of the side panel setting device and the setting frame, the supporting member is erected on the rear side of the side of the setting station or on the side of the setting station. It is conceivable that the machine frame is erected above the machine frame and the support member is erected on the machine frame. In the former case, the elevating frame is largely extended in front of the support member and the jig is attached to the front end portion thereof. Therefore, there is a problem that the lifting frame tends to tilt forward and downward and the positioning accuracy of the jig deteriorates.In the latter case, the lower end position of the lifting frame is at the same level as the machine frame. Because of the high position, there is no choice but to mount the jig below the lifting frame at a considerable distance, and as a result, when the jig is raised to the upper moving position, the lifting frame can be moved to a position considerably above the upper moving position. I have to raise it, I support it If there is a need to significantly increase the height of the up to the top of the timber, it can not be installed on the ceiling of the low place.

On the other hand, when the elevating frame is supported by the elevating bar provided on the machine frame so as to be vertically movable, the elevating bar is lowered when the jig is lowered to the lower moving position. Even when the jig is lowered to the upper position of the jig, the elevator bar is raised to move the set frame into and out of the set station without interfering with the elevator bar through the lower space of the machine frame. As a result, it is possible to guide the elevating frame to the elevating bar and lower it to a position lower than the machine frame when the jig descends. As a result, it is necessary to make a large difference in height between the elevating frame and the jig. As a result, it is possible to suppress the ascending height of the elevating frame when the jig is raised to the upper moving position, and it is possible to install the jig even in a place with a low ceiling.

Further, since the jig can be moved up and down to the up and down positions by the vertical movement of the lifting bar and the vertical movement of the lifting frame with respect to the lifting bar, it is possible to accelerate the lifting speed of the jig and improve efficiency. Becomes
