Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a side panel assembly line for assembling left and right side panels of an automobile.

[0002]

2. Description of the Related Art Conventionally, an assembly line for a left side panel and an assembly line for a right side panel are provided, and a plurality of work stations are arranged in series on each assembly line, so that the left and right side panels are connected to each other. Each of the work stations is conveyed between the work stations by means of the conveyance means, and the side panel is delivered to the holding means installed in each work station, and a required operation is performed on the side panel (Japanese Patent Application Laid-Open No. Sho 62-263876). Gazette).

[0003]

In the above-mentioned prior art, since a separate assembly line for assembling the left and right side panels is provided, a large space is required, and each of the side panels is provided separately from the transport means for the side panels. It is necessary to provide a holding means for the side panel in the work station, and there is a problem that equipment costs are increased.

In view of the above, the present invention enables the left and right side panels to be assembled together, and eliminates the need to provide a holding means for the side panels in each work station, thereby saving space and equipment costs. It is an object of the present invention to provide a side panel assembling line which can reduce the cost of a side panel.

[0005]

Means for Solving the Problems In order to solve the above problems,
The present invention relates to a side panel assembly line for assembling left and right side panels of an automobile, in which a plurality of work stations are arranged in series, a lower frame on both left and right sides, and a gate-shaped frame proud of both lower frames. , An upper frame connected to a gate-shaped frame, and between the lower frame and the upper frame on each of the left and right sides, a female carrier capable of holding the left and right side panels via clamp members mounted on these frames. Equipped with a trolley and a male transport trolley that can enter from the longitudinal direction of the line between both lower frames of the female transport trolley, and a pair of left and right jigs holding left and right side panels is mounted on the male transport trolley. The left and right side panels can be transferred between the female and male transport vehicles with the male transport vehicle entering between the lower frames of the female transport vehicle. Each type of transport trolley is counted from the upstream end of the line so that it can reciprocate between the odd-numbered work stations and the next even-numbered work stations, and each type of transport trolley can be moved from the upstream end of the line. It is possible to reciprocate between the even-numbered work stations and the next odd-numbered work stations, and the left and right side panels are moved from the odd-numbered work stations to the next even-numbered work stations by the one type of carrier. In the state of being transported to each work station, the work robots arranged on both sides of each even-numbered work station perform required work on the left and right side panels, and each of the one type of transport trolleys from the other type of transport trolley. The left and right side panels are transferred to the transport trolley, and the next odd-numbered work station of each even-numbered work station is transferred by the other type of transport trolley. In a state where the left and right side panels are transported to the respective work stations of the eye, required work is performed on the left and right side panels by the work robots arranged on both sides of each of the odd-numbered work stations, and the transfer of the other type is performed. The left and right side panels are configured to be delivered from the cart to each of the one type of transport cart.

According to the present invention, at each work station, after performing the required work on the left and right side panels while holding the left and right side panels on the female or male carrier, the female carrier Transfer the left and right side panels from the female transport vehicle to the male transport vehicle or from the male transport vehicle to the female transport vehicle with the male transport vehicle entering between the left and right lower frames of the truck. Left and right side panels can be transported to the work station. Then, by repeating the above operation, it is possible to perform work at a plurality of work stations on the left and right side panels. Thus, the left and right side panels can be assembled together on a single line, saving space and
There is no need to provide a holding means for the side panel at each work station, so that equipment costs can be reduced.

By the way, after the left and right side panels are transferred from the female carrier to the male carrier or from the male carrier to the female carrier, the side panels of the female carrier and the male carrier are formed. The empty transport vehicle is returned to the work station in front of the delivery vehicle, and the transport vehicle receiving the side panel is moved forward to the next work station. At this time, the interference of the empty transport vehicle with the side panel ( If the empty carrier is a female carrier, the interference between the clamp members mounted on the upper and lower frames and the side panel will occur.If the empty carrier is a male carrier, the jig and side It is necessary to avoid interference with the panel. Here, it is possible to avoid the interference by moving the clamp member of the female transport vehicle outward in the lateral direction, but if the transport vehicle receiving the side panel is a female transport vehicle, it is impossible to attach to the side panel. It is necessary to accurately and synchronously move the plurality of clamp members that hold the side panel so that no excessive stress is applied, so that the moving speed of the clamp member cannot be increased, and the transfer of the side panel starts after the side panel is delivered. The waiting time is longer.

On the other hand, each jig to be mounted on the male transport vehicle is transferred to the bogie main body of the male transport vehicle in a laterally outward direction for transferring the side panel between the female transport vehicle and the jig. If it is supported so as to be able to advance and retreat at the position and the retracted position inward in the lateral direction, the jig can be avoided by moving each jig to the retracted position after the delivery of the side panel. Here, the jig is provided with a plurality of clamp members for gripping the side panel, but since these clamp members move integrally with the jig, even if the moving speed of the jig to the retracted position is increased, the side member is not moved. No excessive stress is applied to the panel,
It is possible to shorten the waiting time from the delivery of the side panel to the start of the transport of the side panel, thereby improving the efficiency.

In order to reduce the time loss due to the transfer of the side panels from the male carrier to the female carrier, a female station is provided at the work station where the left and right side panels are held by the male carrier. It is desired that the transport carrier be moved back before the completion of the work so that the left and right side panels can be immediately transferred to the female transport vehicle after the work is completed. However, when a portal frame is erected at the end of the vehicle to support both ends of the upper frame of the female carrier, the portal frame at the end on the upstream side of the line of the female carrier interferes with the work robot during the operation. Therefore, the female carrier cannot be returned to the work station until the work is completed.
On the other hand, if the female transport carriage is configured such that the portal frame is provided only at the end of the carriage on the downstream side of the line, the work station can be connected to the work robot before the work at the work station is completed. The female carrier can be moved back without negotiating, and the time loss due to the delivery of the side panel can be shortened, and the efficiency can be improved. still,
When the bogie reciprocated between the first working station and the second working station is a female transport bogie and the side panel is set on the female transport bogie at the first work station, 1 Since the work is started after the return of the female transport vehicle to the second work station, the female transport vehicle may be configured to have a portal frame erected at both ends.
