BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slat conveyor wheel stopper structure for transporting a completed vehicle by a slat conveyor in an automobile manufacturing plant.

[0002]

2. Description of the Related Art Conventionally, when a completed vehicle is transported by a slat conveyor in an automobile manufacturing plant, a front wheel 102 is mounted on a part of a mounting plate 101 of the slat conveyor 100 as shown in FIG. It is known to provide a bump 103 for stopping the vehicle, which comes into contact with the vehicle. In this case, since the projection 103 may collide with the transfer plate 104 of the completed vehicle at the end of the slat conveyor 100 traveling in the direction of the arrow, the gap 105 between the lower position of the protrusion 103 and the transfer plate 104 It is necessary to increase the width L1.

For this reason, there is a possibility that a worker's foot may be caught in the gap 105. To improve such a working environment, for example, Japanese Utility Model Publication No. Sho 62-25460 discloses that a slat plate is divided into two parts. It describes that the portion is formed into a V-shaped concave portion when the completed vehicle is fixed by rollers and guide rails, and is formed as a flat shape when the completed vehicle is carried out so as to make the gap as narrow as possible.

Further, Japanese Utility Model Publication No. 63-15211 discloses a structure in which two divided plates are simultaneously lifted to make the carrying out easier.

[Problems to be Solved by the Invention] However, these proposals also have a problem that the cost is higher than that of a normal slat conveyor, and it is not easy to modify an existing slat conveyor as proposed. .

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to reduce the width of the gap between the transfer end of the slat conveyor and the transfer plate. An object of the present invention is to provide a slat conveyor wheel stopper structure which can be set shorter than that of the conventional slat conveyor and can be easily modified even with an existing slat conveyor.

[0007]

In order to solve the above-mentioned problems, the present invention comprises a pair of left and right rollers running on a conveying rail ,
The rollers are sandwiched from inside and outside, and the rollers are bent as nodes.
A pair of left and right inner main link plates for conveyance , and a pair of outer main link plates for conveyance;

It is configured to transport the completed vehicle mounted and fixed on the vehicle.

In the direction of the arrow shown in FIG.
In order to prevent the completed vehicle mounted on the mounting plate 8 from moving on the mounting plate 8 when the vehicle travels, the slat conveyor 1 has a wheel-stopping link with which the front wheels 9 abut at predetermined intervals. A mechanism 10 is provided.

The link mechanisms 10 are adjacent to each other, and are front and rear in the transport direction.
Spaced around the mounting plate 8 arranged, 8 left in (progression
Direction is the reference. Therefore, a pair of sub-link plates 11a and 11b before and after being disposed (see FIG. 2).
When, the placing plate 8, 8 of the right pair of sub link plates 12a before and after disposed (shown above in FIG. 1), 12b
Ru equipped with a door. These left and right sub link plates 11a,
11b, 12a, and 12b have front and rear mounting plates at their base ends.
8 and 8 through the bases 7 and 7
It is pivotally supported by attached pins 14 and 14. A pair of front and rear auxiliary link plates 11a and 11b disposed on the left side described above.
And a pair of front and rear auxiliary link plates 12 disposed on the right side
a and 12b are overlapped with each other,
Part is pivotally supported by a shaft-shaped brace member 13 ,
Is installed so as to cross between the left and right opposite ends.
You.

A pair of front and rear sub-link plates 11a, 11b disposed on the left side of adjacent front and rear mounting plates 8 , 8 are provided.
And a pair of auxiliary link plates 1 before and after being disposed on the right side.
2a and 12b are attached to the left and right sides of each base 7 so as to be freely rotatable with mounting pins 14 each having one end inserted into each base 7;
The other end of each is mounted rotatably on right and left end portions of the wheel stopping member 13 which is disposed in the gap 15 upward between the mounting plate 8, 8 adjacent.

The operation of the wheel stopper structure of the slat conveyor configured as described above will be described with reference to FIGS. 4 shows a state of being conveyed, is mounted on the mounting plate 8, 8 of the slat conveyor 1 as shown in FIG front wheels
The completed vehicle in which W is brought into contact with the vehicle stopper 13 is transported in the direction of the arrow. At this time, the front and rear mounting plates 8, 8 are at the same level.
Of the left and right sub link plates 11a and 11b
Spacing between the shaft supports 14, 14 (mounting pins) on the base 7, 7 side
S1 is small, so that the link mechanism 10 as a whole
Wheel stoppers at opposing ends of auxiliary link plates 11a and 11b
The angle of the pivot portion constituted by the member 13 is small, and the mounting plate
Positioned protruding upward between small gaps 15 between 8, 8
You. Therefore, the vehicle projecting upward between the front and rear mounting plates 8
The front wheel W contacts the wheel stopper 13 and functions as a wheel stopper.
I do.

[0015] completed vehicle is conveyed to the conveyance end near the slat conveyor 1, the mounting of the front and rear as shown in FIG. 5 plate
The mounting plate 8 in front of the base 8 and the inner main link
Transfer plate 1 together with the rate and outer main link plate 5
Go down below 6. Below the front mounting plate 8
The base of the mounting plate 8 at the front part
7 axle support portion 14 (mounting pin) of sub-link plate 11a
And a sub-link of the base 7 of the rear mounting plate 8 in a horizontal state.
Interval between the plate 11b and the shaft support 14 (mounting pin)
S2 becomes wider than the state shown in FIG.
Of the auxiliary link plates 11a and 11b of the link mechanism 10
Of the wheel stop member 1 constituting the shaft support
3 will be lower.

As described above, when the front mounting plate 8 enters under the transfer plate 16, the adjacent mounting plate 8
-Out gradually spread line gap 15 between, also by spreading distance of the base 7 fitted with mounting pins 14, the mounting pin 1
4 spreads like S2, and the sub-link plate 11
a, 11b, 12a, and 12b rotate around the mounting pin 14 at the same time, and at the same time, the auxiliary link plates 11a, 11b.
The opposite ends of b, 12a, and 12b also rotate about the brace member 13 .

Furthermore, when the slat conveyor 1 as shown in FIG. 6 further travels in the direction of the arrow, the front mounting plate 8, next
The angle with the mounting plate 8 immediately after the contact increases,
As the placing plate 8 enters below the transfer plate 16,
The angle between the mounting plates 8 becomes steep, and the sub-link plate 11
The distance between the shaft support portions 14 and 14 (mounting pins) of
As shown in S3 of FIG.
The angle between a and 11b is increased, and the shaft support at the opposite end,
That is, the wheel stopper 13 is further lowered. Therefore, FIG.
As shown, the gap 15 between the mounting plates 8, 8 is enlarged,
The angle of the angle of the link mechanism 10 becomes larger and the wheel stopper
Since the material 13 is lowered, the mounting plate 8 and the transfer plate 16
The wheel stopper 13 is transported with the gap L2 between
It can be lowered at the end.

Therefore, the car stop member 13 does not always protrude above the mounting plate 101 like the prior art car stop protrusion 103 shown in FIG. 7, and the link mechanism 10 operates at the transport end of the slat conveyor 1. As a result, the stop member 13 descends in the direction of the mounting plate 8, so that the width L2 of the gap 17 between the lowering position of the mounting plate 8 and the transfer plate 16 can be set shorter than the width L1 in the conventional technology. Become.
