Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a transfer device for assembling a car in a car manufacturing factory or the like.

<Conventional technology> In an automobile assembly line, an operator gets on a body conveyed by a conveyor and assembles various parts.

A slat conveyor or a trolley conveyor that travels at regular intervals is generally used as a conveyor for transporting the body.

In any of these conveyors, a component transporting trolley storing components, tools, and the like to be mounted on the body is provided so as to synchronize with the traveling movement of the body.

For example, as shown in FIG. 4, the body 3 is mounted on the slat conveyor 2 on the same plane as the floor 1 via the positioning support legs 7 of the body 3, and a pair of right and left is placed on the floor 1 on the side of the slat conveyor 2. A rail 5 is laid thereon, and a carrier 4 for parts and the like is movably mounted on the rail 5. A connecting bar detachable from the carrier 4 for the parts and the like on the positioning support leg 7 of the body 3 on the slat conveyor 2. This is a structure provided with a synchronizing cylinder device 6 provided with 6a.

<Problem to be Solved by the Invention> As shown in FIG. 5, in the transport device, the transport vehicle 4 such as a part moves the body 4 from the start position A to the end position B during a fixed travel range of the body 3. The worker who travels in synchronism with the movement and gets into the body 3 takes out required parts and tools from the carrier 4 such as parts and assembles them.

However, since the transport vehicle 4 is running synchronously on the floor 1 farther away from the position of the body 3, it is very inconvenient to take out parts and tools.

In order to solve this problem, it is satisfactory to move the parts carrier 4 closer to the body 3. However, in the case of the slat conveyor 2 or the carriage conveyor moving at a constant interval, the parts carrier 4 is moved more than the body 3. It is impossible to get close to the side.

<Means for Solving the Problems> The present invention has been made in view of the above-described conventional problems, and has made it possible to approach the position of a transporting trolley for parts and the like, which was impossible in the past, to the body side. A friction conveyor that abuts the front and rear ends of a plurality of body transporting trolleys on which a vehicle body is mounted and travels on the same plane as the floor, and is laid on the floor along the traveling line of the body transporting trolley. A guide rail, a flat rail fixed on the side end of the body transporting cart in parallel with the guide rail, and one of the left and right wheels is positioned and regulated in the left and right direction by both flange wheels and guided by the guide rail,
The other wheel includes a traveling wheel mounted on a flat rail on the body transport vehicle by a flat wheel, has a synchronization cylinder device detachable from the body transport vehicle, and is mounted on the body transport vehicle. Parts and tools to be assembled to the set body, and a carriage for moving parts synchronously with the body carriage for straddling between the floor and the body carriage. It is.

<Operation> According to the above configuration, one of the left and right wheels of the carriage for transporting parts and the like is guided by guide rails on the floor in a position-regulated manner in the left and right directions, and the other flat wheel is used for body transportation. Riding on the trolley, it is placed on a flat rail and straddles between the floor and the body transport trolley so that it can move synchronously with the body transport trolley, so that the transport trolley such as parts can be as close as possible to the body, This facilitates removal of tools and the like.

An embodiment of the present invention will be described below with reference to the drawings. First
In the figure, reference numeral 10 denotes a floor 1 on which an automobile body 3 is mounted.
Are a plurality of body transport vehicles that travel and move on the same plane, and are friction conveyors that travel by abutting the front and rear ends of the body transport vehicle 10 with each other. Reference numeral 11 denotes a guide rail laid on the floor 1 along a traveling line of the body transport trolley 10, and 12 denotes a flat rail fixed on the side end of the body transport trolley 10 in parallel with the guide rail 11. Rails. Reference numeral 4 denotes a transporting trolley for storing parts, tools, and the like that move synchronously with the body transporting trolley 10 on the guide rail 11 and the flat rail 12 across the floor 1 and the body transporting trolley 10. is there.

As shown in FIG. 2, the carriage 4 for the parts and the like is provided with a connecting bar 6a which can be attached to and detached from the positioning support leg 7 of the body 3 provided on the body carrier 10 as in the prior art. Cylinder 6 is provided.

As shown in FIG. 3, one of a pair of left and right wheels is a double-flanged wheel 13, which is guided by the guide rail 11 while being positioned and regulated in the left-right direction by the two flanges, and the other is a flat wheel 14. And is mounted on the flat rail 12 on the body transporting trolley 10 across the body transporting trolley 10.

Since the present invention has the structure as described above, in FIG. 1, the parts and the like which have been moved synchronously with the body transporting cart 10 to the end position B for taking out the parts and the like on the body 3 on the front body transporting cart 10 are described. The transport vehicle 4 is connected to its connecting bar 6a.
From the positioning support leg 7 of the body 3 and return to the start position A.

At this time, the flat wheels 14 traveling on the flat rails 12 fixed to the body transporting cart 10 are attached to the front body transporting cart 10 at the front end in a ball-like manner. Flat rail 12 of transport cart 10
The two rim wheels 13 that move up and are guided by the guide rails 11 on the floor 1 constantly regulate the positioning in the left-right direction.

At the start position A, the synchronizing cylinder device 6 is actuated to connect the connecting bar 6a to the positioning support leg 7 of the body 3 of the succeeding body transporting carriage 10, and the body transporting carriage 4 following the transporting carriage 4 for parts and the like. The worker who travels in synchronism with the traveling movement of the body 10 and gets into the body 3 takes out the parts to be assembled from the carrier 4 such as parts and the tool.

By the way, the parts to be assembled from the transport cart 4 for the parts and the like, and the pick-up cart 4
Most of them are located on the body transporting cart 10 and are close to the body 3, so that the worker who gets on the body 3 can obtain work such as taking out parts and tools at hand.

<Effect of the Invention> As described above, the present invention conveys parts and the like in a friction conveyor that travels on the same plane as the floor by abutting the front and rear ends of a plurality of body conveyance trolleys on which the body of the vehicle is mounted. The bogie has one of its left and right wheels, one of which is guided and guided by guide rails on the floor in a position-regulated manner in the left and right direction, and the other flat wheel is mounted on a body transporting bogie and placed on the flat rail. Since it is configured to be able to move synchronously with the body transporting trolley across the floor and the body transporting trolley, the worker who gets on the body and assembles the parts is closest to the body,
In addition, parts and tools can be easily removed from the transport cart, such as parts that move synchronously with the body transport cart, while maintaining a predetermined position close to the body transport cart, and workability is improved. I do.

In addition, when transferring the carriage of parts and the like to the subsequent body transporting carriage, both flange wheels are positioned in the left and right direction by the guide rail on the floor, and the flat wheels transfer to the flat rail of the subsequent body transporting carriage, There is an advantage that the transfer cart for parts and the like can be smoothly transferred while maintaining a predetermined position interval close to the following body transfer cart.
