Abstract

PURPOSE:To contract the floor occupying space of the whole equipment by placing directly parts, shelves stored with assembly parts on each work transfer truck of an automobile assembly line and, transferring the parts shelves and work pieces together by a work transfer truck. CONSTITUTION:Plural shelves placing parts 4 are provided in series state in a traveling direction on each work transfer truck 2 of an an automatic assembly line 1. A shelf transfer device 9 is provided with a hanger 12 for suspending a shelf at the lower side of the suspension type monorail electric car 11 which self-travels along a guide rail 10. A part shelf 16 loaded with parts is transferred to the shelf unloading route part 14 of the upper part of the start end part of the line 1 by traveling the electric car 11 along the guide rail 10. The parts shelf 16 is then removed from the hanger 12 for the shelf suspension and placed on the shelf placing part 4 located on the work transfer truck 2 just under. The parts assembled to one unit of an automobile body 3 are placed by being divided in three part shelves 16.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system for supplying assembly parts to an assembly line for automobiles and the like.

(Prior art and its problems) On an automobile assembly line, necessary parts are assembled to the automobile body on each workpiece carrier (so-called frixine cart) that moves at a constant speed on the assembly line. Since the automobile bodies to be worked on are continuously moving at a constant speed, the parts to be assembled for each automobile body must also be transported at the same speed to a position close to each automobile body.

For this reason, in the past, parts shelf conveyance equipment was provided for synchronously conveying shelves on which assembled parts were placed parallel to the assembly line. Therefore, not only does the entire equipment become very expensive, but it also occupies a large floor area, resulting in low floor space utilization efficiency.

(Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention has the following features:
Each workpiece transport vehicle moving on an assembly line such as an automobile is provided with a shelf mounting section for mounting parts to be assembled, and the assembly parts mounting shelf transported by a shelf transport device to the starting end of the assembly line is Transfer it to the shelf mounting section of the workpiece transport vehicle,
The present invention proposes a parts supply system for an assembly line for automobiles, etc., in which the assembled parts mounting shelf and the workpiece are transported together by the workpiece transport vehicle.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

Reference numeral 1 denotes an automobile assembly line in which workpiece carriers 2 run at constant speeds at regular intervals, and each workpiece carrier 2 has a plurality of shelf placement parts 4 on one side of the location where the automobile body 3 is supported. are provided in series in the running direction. Reference numeral 5 denotes a parts kit production area, which includes a parts storage area 6, a parts storage rack 7, and a kit production area 8. Reference numeral 9 denotes a shelf conveying device, and as shown in FIG.
This electric train 1 is equipped with a hanger 12 for the lower part of the suspension type rail car 11 that runs on its own along 0.
During the travel route 1, the parts loading route section 13 passes above the kit work area 8, and directly above the shelf placement section 4 of each workpiece carrier 2 on the automobile assembly line 1. A shelf unloading route section 14 and a blank loading route section 15 are provided. Reference numeral 16 denotes a parts shelf that can be placed on the shelf mounting section 4 of each of the workpiece transport vehicles 2, and can be suspended by the hanger 12 for the lower part of the train 11.

Parts brought in from outside using hand carts or the like are temporarily stored in a parts storage area 6. Then, the parts in the parts storage area 6 are sorted by type and stored in the parts storage rack 7 by the operator. This component storage rack 7 has conventionally well-known articles placed on the article replenishment side at the rear end of the rack that is configured to slide by gravity toward the article retrieval side at the front end of the rack. A fluidized shelf can be used by arranging the article supply side adjacent to the parts storage area 6 and the article retrieval side adjacent to the kit production work area 8.

Parts kitting work is done in kitting work area 8.
The required number of specified multiple types of parts are each taken out from the parts storage m7 and loaded onto the empty parts shelf 16 suspended from the waiting train 11 in the parts loading route section 13 above the kit work area 8. The parts $J116 loaded with zero parts are transported to the unshelf-unloading route section 14 above the starting end of the automobile assembly line 1 by making the train 11 travel along the guide rails 10. And from the hanger 12 for the lower part of the specimen, the parts shelf 16
In the illustrated example, parts to be assembled on one automobile body 3 are placed separately on three parts shelves 16. Therefore, there are three parts shelves 1 on one workpiece transport vehicle 2.
6 is placed. The standard hanger 12 for the train 11 is
It goes without saying that it can be opened and closed, but it is preferable to use a conventionally known hoist type that can raise and lower the suspended parts shelf 16.

On the workpiece carrier 2, the worker riding on the carrier 2 takes out the parts from the parts shelf 16 placed on the carrier 2 before the carrier 2 reaches the end of the automobile assembly line 1. A workpiece carrier 2 is installed at the end of the automobile assembly line 1 to perform assembly work on the automobile body 3.
By the time , the work of assembling the parts to the automobile body 3 has been completed, and the parts [16] placed on each workpiece carrier 2 are in an empty state. Therefore, the empty loading path section 15 above the end of the automobile assembly line 1
At this time, the empty parts shelf 16 on the workpiece transport vehicle 2 is hung from the empty hanger 12 of the waiting train 11, and the empty parts shelf 16 is transported by the train 11 to the kit production area 8, and the parts shelf 16 is opened. Can be used repeatedly.

Of course, the empty parts shelf 16 can also be transported to the kit production area 8 by another transport means.

Note that the Enoki transport device 9 is not limited to the type that uses the suspended mole rail train 11 as in the embodiment.

(Operations and Effects of the Invention) As described above, according to the parts supply system for an automobile assembly line of the present invention, a parts shelf storing assembled parts is directly placed on each workpiece carrier moving on an assembly line. However, since the parts shelf and the workpiece are transported together by the workpiece transport vehicle, there is no need for a dedicated transport means for the parts shelf that transports the parts shelf in parallel at the same speed as the workpiece transport vehicle, which significantly increases equipment costs. A significant reduction is possible. In addition, since it is only necessary to use a workpiece transport vehicle that is wider than the conventional workpiece transport vehicle by the width of the shelf mounting section, a dedicated transport means for parts shelves must be installed adjacent to the travel path of the workpiece transport vehicle. The floor space occupied by the entire equipment is also reduced compared to what would otherwise be the case, and floor space utilization efficiency can be increased. Furthermore, since the parts shelf is placed directly on the workpiece carrier, the distance between the parts placement position and the workpiece (automobile body, etc.) is shortened, and parts assembly work can be carried out efficiently.
