Abstract

PURPOSE:To improve working efficiency in parts assembling by placing a working carriage aside a conveying device such as a conveyer for parts assembling line to thereby move the working carriage synchronously with the conveying device. CONSTITUTION:Aside a conveying device 1 such as a conveyer to convey assembled parts 2, rails 3 are laid, and a motor 6 driven working carriage 4 capable of reciprocal running is placed on the rails 3. Running speed of the working carriage 4 can be synchronized with that of the conveying device 1 by controlling the motor 6. On the working carriage 4, a parts conveying and supporting carriage 7 and a hoist 18 running on rails 8 are installed. While in assembling parts, parts 21 are put on a receiver 14 through the hoist 18, the supporting carriage 7 is advanced when assembled parts 2 are conveyed aside the working carriage 4, and the working carriage 4 is driven forward or backward to match the position of the parts 21 with that of the assembled parts 2. After the position matching, the working carriage 4 is moved synchronously with the conveying device 1. A worker on the working carriage 4, thereby, can assemble the parts 21 to the assembled parts 2 in such a manner as in the case of steady state.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a work distribution vehicle that moves in synchronization with a conveyance means such as a conveyor that conveys articles to be assembled one time in an article assembly line. <Prior Art and Problems> In an article assembly line, articles to be assembled one time are transported by a conveyor such as a conveyor.

Conventionally, one worker assembled parts while moving in accordance with the speed of a conveyor, etc.

Therefore, if one part is small and lightweight, there is almost no problem, but if one part is large and heavy, assembly work becomes difficult.

Means for Solving the Problems> The present invention has been made in view of the above-mentioned vehicle situation, and includes a means for moving an article to be assembled with respect to a worker and an article on the conveying means together with a conveying means for the article. The purpose is to facilitate @ marking work.

The structure of the present invention that achieves the above objects is as follows: (1) A working step is provided on the side of a conveying means for conveying the articles to be assembled, so that it can move in synchronization with the conveying means and can independently reciprocate; The present invention is characterized in that a support cart for supplying parts to articles on the conveyance means is movable forward and backward relative to the conveyance means.

Embodiment Fig. 1.2 shows an embodiment in which the present invention is applied to propeller shaft assembly work on a trunk assembly line, and Fig. 1 shows a perspective external appearance of a work trolley according to the embodiment. FIG. 2 shows its side view.

1 is a chain conveyor in a truck assembly line, on which a trunk frame 2 is conveyed.

On the side of the chain conveyor l, a rail 3 is laid parallel to the chain conveyor l, and on the rail 3, a work step (cart body) 4 of a stroke work cart is mounted via attached wheels 5. .

The wheels 5 are driven by a pneumatic motor 6 built into the work platform 4 either directly or via a suitable power transmission mechanism (gear train, chain sprocket, etc.). The pneumatic motor 6 is controlled so that the wheels 5 on its output shaft are synchronized with the chain conveyor I. Incidentally, the starting and stopping of the pneumatic motor 6 depends on the operator standing on the work platform 4 operating the operation panel.

Several parts transport support carts 7 are installed on the work platform 4. 5t=C A quaternary rail provided on the work step 4 perpendicular to the moving direction of the step 4, and a support cart 7
is driven back and forth along this rail 8. The support cart 7 has wheels 9, a base 1O, a lifting cylinder 11 provided upward on the base 1O, a frame 13 connected to the tip of the piston rod 12 of the cylinder 11, and a frame 13. The chain conveyor consists of a support 815 which extends to l'[tl and has a metal fitting 14 at its tip. The movement of the base lO in the support cart 7 and the raising and lowering of the cylinder 11 are also performed by the operator operating the operation panel.

Four pillars 16 are erected on the work platform 4, and pillar 1
At the top of 6, there is a beam 1 in the direction perpendicular to the moving direction of the step stool 4.
7 is attached, and a movable beam 18 is passed between the beams 17 so that it can be driven back and forth between the beams 17 and 17J. A hoist 19 is attached to the moving beam 18 to move the beam IJIH.
() Equipped to be movable along.

In FIG. 1, 20 is an NFC control device installed on the work platform 4. Moreover, small parts (bolts, nuts, etc.) and tools are changed on the work platform 4.

Next, the procedure for attaching the propeller shaft to the frame 2 on the chain conveyor l using the above-mentioned apparatus will be explained.

Propeller shirt) 2Xi is stored at a predetermined location near the work platform 4. A propeller shirt (21) that matches the frame 2 being conveyed by the chain conveyor (1) is selected by the operator, and the support of the support cart (7) is placed on the metal fitting (14) using the whisk (19). At this time, seven support carts are in the backward position, and one work platform 4 is stopped.

When the frame 2 comes to the side of the work platform 4.

The support truck 7 moves forward and projects the propeller shaft 21% below the frame 2, as shown by the two-dot chain line in FIG. At the same time, the mounting position of the front edge of the step stool 4 and the propeller shaft 21 is aligned.

When the installation position of the propeller shaft 21 is aligned, the work step stool 4
is moved in synchronization with the chain conveyor 1, thereby eliminating the need to connect the propeller shaft 21.

In the case of assembling a plurality of propeller shafts, the supports of the support cart 7 on one work platform 4 may be connected in advance on the metal fittings 14, and then assembled on the frame 2 side.

Since the worker works on the work platform 4 which moves in synchronization with the chain conveyor 1, the worker can perform the work in the same way as in a stationary state.

After the work is completed, the first work step 4 is quickly moved in the opposite direction and returned to prepare the propeller shaft to be assembled to the first frame.

In the above embodiment, the propeller shaft is attached to the truck frame as an example.

The present invention is applicable to any article assembly line. Further, the drive source for the one bogie body is not limited to the sudden pressure motor, but it is also possible to use an electric motor or something else.

<Effects of the Invention> According to the work trolley according to the present invention, since the step on which one worker stands moves in synchronization with the conveying means for conveying the work object, one assembly work can be performed in the same state as in a stationary state. ←It becomes easier to work with the rod. Furthermore, during one assembly operation, the parts can be supported on the object to be assembled using the support cart, which makes one assembly easier, and there is no need for the worker to support the parts.

It also reduces the burden. Furthermore, you can store small parts and necessary tools on the step stool.

Transportation work can be omitted, and the performance of the vehicle can be improved.
