DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling work apparatus used for assembling a plurality of sub-components on a main component.

[0002]

2. Description of the Related Art Generally, interior parts for vehicles are manufactured by assembling a main part with a plurality of sub-parts.
For example, the door panel has a panel body as the main part,
It is manufactured by assembling weather strips, switches, covers, clips, armrests and the like as sub-parts.

[0003] Usually, when assembling sub-components into main components, an assembly operation device is used. A conventional assembling work apparatus includes a belt conveyor that transports main parts, and worktables arranged at appropriate intervals along the belt conveyor, and workers are arranged near each worktable. . The operator transfers the main parts conveyed by the belt conveyor to the work table, and assembles the sub-parts in charge into the main parts. After that, the main parts are returned to the belt conveyor. By performing this for each worker, all the sub-parts are assembled into the main part. Therefore, when the main parts are conveyed to the end of the belt conveyor, a finished product is manufactured.

[0004]

In the conventional assembling work apparatus, in addition to the work of the main body in which each worker assembles the sub-parts into the main parts, the main parts are transferred between the belt conveyor and the work table. Since extra work is required, there has been a problem that work efficiency is reduced. In particular,
When the main parts are relatively large, there is a problem that the operator is tired. In addition, when the main part is transferred, the main part may be damaged by hitting or rubbing against another object, which may deteriorate the quality of the product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an embodiment of the present invention. The assembling apparatus 1 includes a support 2. On the support 2, a circular rotary table 3 is placed horizontally.
The turntable 3 is rotatably supported on the support base 2 about a vertical axis passing through the center thereof. The motor is rotated in a direction indicated by an arrow X at a constant low speed via a speed reduction mechanism (both not shown) by a rotary drive source such as a motor. The turntable 3 may be rotated intermittently.

A plurality of work tables 4 are provided on the upper surface of the turntable 3. The number of worktables 4 to be installed is appropriately determined according to the number of sub-components, the number of workers arranged around the turntable 3, and the like. Each worktable 4 includes a rotary table 3
Are arranged at regular intervals in the circumferential direction on one circle centered on the rotation axis.

The work table 4 has a fixed part 41 fixed to the upper surface of the turntable 2 and a rotary part 42 arranged above the fixed part 41. The rotating part 42 has a main part (not shown) to which it is detachably attached.
In this embodiment, the main part is formed in a circular plate shape. However, the main part can be easily attached and detached, and the main part can be easily assembled with the sub part. It is desirable to form it into an appropriate shape. The rotating unit 42 is rotatably supported by the fixed unit 41.
The rotating section 42 is arranged rotatably about a vertical axis passing through the center thereof, but may be rotated about another axis. By allowing the rotating part 42 to which the main component is attached to be rotatable, it is possible to orient the mounting position of the main component in a desired direction in which the work can be easily performed when attaching the sub component to the main component. However, the rotating part 42
If the is rotated too lightly, it may be difficult to assemble the sub-parts. Therefore, it is desirable to provide a braking mechanism between the fixed portion 41 and the rotating portion 42 for regulating the rotation of the rotating portion 42 with a predetermined force. It is further desirable for the braking mechanism to be able to adjust the braking force or to be able to switch between a state in which the braking force is exerted and a state in which the braking force is not exerted.

A carry-in table 5 and a carry-out table 6 are provided radially outside the rotary table 3. The carry-in table 5 is used when attaching main parts to the work table 4, and the main parts are transferred from the carry-in table 5 to the work table 4. on the other hand,
The finished product in which all the sub-components are attached to the main component is transferred from the work table 4 to the carry-out platform 6. The carry-in table 5 and the carry-out table 6 are spaced apart from each other in the circumferential direction of the rotary table 3 by the same interval (angle) between two worktables 4 and 4 adjacent in the circumferential direction of the rotary table 3. Therefore, when the work table 4 on the front side in the rotation direction of the work table 3 is located at the center of the carry-in table 5 in the width direction of the two work tables 4 and 4 adjacent to each other in the circumferential direction of the turntable 3, Workbench 4
Is located at the center of the discharge table 6 in the width direction.

[0010] Around the rotary table 3, an operator for assembling sub-components into main components is arranged. In the case of this embodiment, each worker is required to turn table 3 in FIG.
Are arranged so as to face the six work tables 4 except for the work tables 4 and 4 which face the carry-in table 5 and the carry-out table 6, respectively. Each worker may assemble one sub-part, or assemble one or more sub-parts different from each other.

In the center of the turntable 3, a through hole 31 is provided.
Are formed. The sub-component housing shelf 7 is disposed in the through hole 31 so as to penetrate vertically. The sub-parts storage shelf 7 is placed on the floor. Therefore, the auxiliary component storage shelf 7 is independent of the turntable 3 and does not rotate together with the turntable 3. The upper part protruding upward from the through hole 31 of the sub-component housing shelf 7 has
By a plurality of partition plates 71 arranged apart from each other in the circumferential direction of the turntable 3, a plurality of sub-component housings 72 are provided in the circumferential direction. Each of the sub-parts storage units 72 is arranged so as to face each worker, and each of the sub-parts storage units 72 stores a sub-part which is in charge of each of the opposing workers. In addition, each of the sub-component housings 72 has an open front surface facing outward in the radial direction of the turntable 3. Therefore, each worker can take out the sub-part in charge from the sub-part housing part 72. In order that each worker can easily take out the sub-part from the sub-part housing part 72,
The sub-component housing 72 may be protruded above the turntable 3. In this case, it is a matter of course that the overhanging portion should not be in the way when placing the main component on the work table 4 or rotating the main component.

The sub-component housing section 72 is vertically divided into a plurality of parts by a plurality of horizontal shelves 73 vertically separated from each other.
This allows more sub-parts to be accommodated, or the upper and lower parts of the sub-part accommodating portion 72 can be bolted and nuts used when assembling sub-parts into main parts. Alternatively, an assembly member such as an adhesive can be accommodated.

Although not shown in FIG. 1 for convenience of illustration, a tool support member 8 shown in FIG. 2 is installed above the turntable 3. This tool support member 8 has a support ring 81. The support ring 81 has substantially the same outer diameter as the turntable 3, and is arranged substantially concentrically above the turntable 3. A plurality of tool attachment hooks (tool attachment portions) 82 are provided on the support ring 81.
Is provided. Each tool mounting hook 82 is arranged at a position corresponding to the position of each worker in the circumferential direction of the turntable 3, and a tool used when each worker assembles a sub-part in charge of the worker into a main part is attached and detached. It is possible to attach it. In this case, the tool is arranged at such a height that the tool does not hit the head of the worker and can be attached and detached with the hand extended upward. When a tool is not required for assembling the sub-part, a storage box or the like for storing the sub-part or the assembly member may be attached.

When assembling sub-components into main components using the assembling work apparatus 1 having the above configuration, the main components mounted on the loading table 5 are attached to the work table 4. The main components attached to the worktable 4 are sequentially sent to each worker as the turntable 3 rotates. Each worker takes out the sub-parts and the assembly members from the sub-parts accommodation part 72 when the main parts are transported before himself. At this time, since the sub-parts and the assembling members are arranged at the center of the turntable 3, there is no need to arrange them around the turntable 3, so that the working environment can be improved. In addition, when sub-components are arranged around the rotary table 3, the operator must change the direction each time the sub-components are taken out.
When it is arranged at the center of the turntable 3, the operator can take out the sub-parts while facing forward without changing the direction.

Each worker assembles the removed sub-parts into main parts using tools and assembly members. At this time, since the worktable 4 is provided on the turntable 3, there is no need to transfer main components from the turntable 3. Therefore, it is possible to save time and effort required for transfer, thereby improving work efficiency and reducing operator fatigue. Moreover, the workers
By rotating the work table 4, the assembly location of the main part where the sub-part in charge is assembled can be directed in an appropriate direction. This makes it easy to assemble the sub-part in charge.

The finished product to which all the sub-components are attached by each worker is transferred from the work table 4 to the discharge table 6 at a position facing the discharge table 6. Then, a new main part is transferred from the carry-in table 5 to the empty work table 4.

Next, another embodiment of the present invention shown in FIG. 3 will be described. In this embodiment, only the configuration different from the above-described embodiment will be described, and the description of the same parts will be omitted.

In the assembling work apparatus 1 'of this embodiment, the rotary table 3 has a plurality (4 in this embodiment).
) Sub-rotary tables 9 are provided horizontally. Each sub turntable 9 has a circular shape whose outer diameter is slightly smaller than the width between the outer peripheral surface of the turntable 3 and the through hole 31, and is arranged at equal intervals in the circumferential direction of the turntable 3. . The sub turntable 9 is rotatably supported by the turntable 3 about a vertical axis passing through the center thereof. It is desirable to provide a braking mechanism similar to the braking mechanism provided between the rotary table 3 and the worktable 4 between the rotary table 3 and the sub-rotary table 9.

Each sub turntable 9 is provided with a plurality of (four in this embodiment) work tables 4. In this case, the entire worktable 4 is rotatably provided on the sub-rotary table 9, but the worktable 4 may be composed of a fixed part and a rotating part as in the above-described embodiment. The work tables 4 are arranged at regular intervals in the circumferential direction of the sub-rotary table 9, but need not necessarily be arranged at regular intervals.

In this embodiment, the number of workers (four) corresponding to the number of sub-rotary tables 9 is arranged. The carry-in table 5 and the carry-out table 6 are arranged between two workers adjacent to each other in the circumferential direction of the rotary table 3 in a state where they are almost in contact with each other.

The assembly work apparatus 1 'described above can be used in various modes as described below. For example, one use mode is to attach the same main component to all worktables 4. In this case, each worker first rotates the sub-rotary table 9 appropriately, and
Is positioned on the near side. Then, the sub-parts are assembled to the main parts attached to the work table 4. Next, the sub-rotating table 9 is rotated by 90 ° to position the other worktable 4 on the near side, and the subpart is assembled to the main part attached to the worktable 4. This is repeated by the number of the work tables 4 provided on the sub-rotary table 9 (four), while the sub-rotary table 9 passes in front of each worker as the rotary table 3 rotates. The same applies to other workers. Thereby, all the sub-parts are assembled to the main part. Therefore, this usage mode is the same as the usage mode of the above-described embodiment except that each sub turntable 9 is rotated.

In another mode of use, one auxiliary rotary table 9 is used.
The main components different from each other are attached to the respective worktables 4 provided in each of the work tables. In this case, each worker:
First, the sub-rotating table 9 is appropriately rotated to position the main part in charge of itself on the near side, and all the sub-parts are assembled to the main part. This is performed while the sub turntable 9 passes along with the rotation of the turntable 3. The same applies to other workers.

Further, as a modification of the above other use mode,
Among the worktables 4 provided on one auxiliary rotary table 9,
Some worktables 4 (for example, one or two worktables 4) have different main parts attached thereto, and the remaining worktables (for example, three or two worktables 4) have the same main parts (e.g., three worktables 4). A main part different from the main parts attached to some of the worktables 4) is attached. In such a usage mode, different finished products are assembled in different numbers during one rotation of the turntable 3, so that each finished product can be manufactured in accordance with the required number of manufactured products. Also in this case, each worker attaches all the sub-parts to the main part which he is in charge of.

It should be noted that the present invention is not limited to the above-described embodiment, and can be appropriately changed. For example, a plurality of boxes accommodating relatively small mounting members such as bolts, nuts, and clips used when mounting the sub-components to the main component are appropriately spaced in the circumferential direction of the rotary table 3 on the outer peripheral portion of the rotary table 3. It may be arranged for each and rotated together with the turntable 3. This box may be arranged on the floor surface and made independent of the turntable 3.

[0025]

As described above, according to the present invention, the extra work of transferring the main parts between the belt conveyor or the like and the work table becomes unnecessary. Therefore, it is possible to improve the efficiency of the work, to reduce the fatigue of the worker, and to prevent the damage when transferring the main parts, thereby improving the quality of the product. can get.
