DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slat conveyor device having a wheel stopper.

[0002]

2. Description of the Related Art At an assembly site of an automobile or the like, a slat conveyor having a wheel stopper is used to stop a work such as a vehicle.

[0003] A conventional slat conveyor 1 having a wheel stopper
In No. 0, two trapezoids were provided at intervals to place the wheels 16 as the workpieces to be transported to form a set of wheel stoppers 11. In one trapezoid, a protrusion having a trapezoidal cross section was fixed on the slat conveyor over the width direction of the conveyor.

Further, a slat conveyor 1 having a wheel stopper
On the downstream side of the slat conveyor, the gap between the entangled portion 12 at the downstream end of the slat conveyor and the floor end 13 in the next step is large, and the gap 18 is formed at the downstream side of the slat conveyor. One plate-shaped safety cover 14 is formed so as to be parallel to the slat conveyor surface and project toward the slat conveyor so as to cover the gap 18 (see FIGS. 3 and 4).

[0005]

However, in the conventional slat conveyor device having a wheel stopper, since the wheel stopper 11 protrudes in a trapezoidal shape that is long in the width direction of the conveyor, the entangled portion at the end of the slat conveyor device is required. A gap 15 corresponding to the height of the trapezoidal projection has to be formed between the upper surface of the slat conveyor 10 and the lower surface of one safety cover 14. Then, there is a problem that the foot 17 of the worker is easily caught in the gap portion 15.

[0006]

[Means for solving the problem] In order to solve this problem,
A plurality of protrusions are arranged in parallel in the width direction of the conveyor on the slat conveyor surface, with a plurality of protrusions arranged side by side, a floor end facing the end of the slat conveyor, and a protrusion in the conveyor direction from the floor end in the width direction of the conveyor. The safety cover is formed by arranging a plurality of protrusions in parallel with a gap, and the plurality of protrusions of the wheel stopper protrusion and the plurality of protrusions of the safety cover are provided at positions where they do not coincide with the slat conveyor in the width direction. A slat conveyor device having a characteristic wheel stopper is proposed.

Also, a plurality of trapezoidal plate-like projections are provided in parallel on the surface of the slat conveyor with a gap in the width direction of the conveyor, a wheel stopper projection, a floor end facing the slat conveyor end, and a floor end. A safety cover formed by projecting in the direction of the conveyor from the front and leaving a gap in the width direction of the conveyor with a plurality of plate-shaped protrusions arranged side by side. Is provided at a position that does not coincide with the slat conveyor in the width direction.

Therefore, the plurality of projections of the wheel stopper projections and the plurality of projections of the safety cover pass each other without collision even when the slat conveyor operates.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a downstream end of a slat conveyor having a wheel stopper, and FIG. 2 is a side view of the same. It will be described based on the following.

The slat conveyor 1 is provided with a plurality of wheel stoppers 2 on the upper surface of the conveyor in the conveyor moving direction. One of the wheel stoppers 2 includes a pair of wheel stopper protrusions 20 provided with a gap in the moving direction of the conveyor. One wheel stopper projection 20 is formed by arranging a plurality of side plate trapezoidal projections 20a from the upper surface of the conveyor with a gap 20b in the width direction of the conveyor. In this embodiment, the plate-like projections 20a
The sheets are arranged in parallel with the same three gaps 20b. The thickness of one plate-like projection 20a is about 10 to 15 mm, and the gap 2
The width of Ob is about 10 to 50 mm.

As another embodiment of the wheel stopper projection 20, two, three, five or more plate-like projections 20a can be provided in parallel in the conveyor width direction with a plurality of gaps 20b. is there.

As another embodiment of the wheel stopper projection 20, another shape projection 20a such as a columnar projection may be provided with a plurality of gaps 20b in the width direction of the conveyor.

A safety cover 4 is provided at the floor end 3 facing the downstream end and the upstream end of the slat conveyor 1. The safety cover 4 extends from the floor end 3 to the slat conveyor 1
It is provided to project to the side. The safety cover 4 covers a gap 18 formed between the winding portion 12 at the downstream end of the slat conveyor 1 and the floor end 3 and projects in the direction of the slat conveyor 1 so as to contact the horizontally moving portion of the slat conveyor 1. Project to the position.

The safety cover 4 includes a plurality of plate-like projections 40a each having a trapezoidal side surface with a long bottom side and a plurality of gaps 4 in the width direction of the conveyor.
0b are provided in parallel with each other.
Is fixed to the floor end 3 at a part of the bottom of the long trapezoid.
In this embodiment, five plate-shaped protrusions 40a are arranged in parallel with the same four gaps 40b in the width direction of the conveyor.
Each of the four gaps 40b has such a width that one plate-like projection 20a of the wheel stopper projection 20 of the slat conveyor 1 can pass through. The thickness of one plate-like projection 40a is 10 to 15 m.
m, and the width of the gap 40b is about 10 to 50 mm.

In another embodiment, two, three, four, or six or more plate-like protrusions 40a are formed in the width direction of the conveyor by forming a plurality of gaps 40b. It is also possible to provide them in parallel, and in this case also, the plate-shaped projections 20a of the wheel stopper projections 20 of the slat conveyor 1
The columnar projections 20a and the like are arranged so as to pass each other and pass each other.

The wheel stopper projections 20 and the safety cover 4 are formed of an elastic material such as a soft synthetic resin or rubber.

Next, the operation of the embodiment of the present invention will be described. Both the wheel stopper 2 of the slat conveyor 1 and the safety cover 4 of the floor end 3 are composed of a plurality of plate-like projections 20a, 40a and a plurality of gaps 20b, 40b. After passing through 40b, they are arranged at positions shifted in the width direction of the conveyor so as to pass each other.

Therefore, the safety cover 4 protrudes from the floor end 3 on the downstream side and the upstream side of the slat conveyor 1 in the direction of the slat conveyor 1 to completely cover the gap portion 18 and to cover the horizontal moving surface of the slat conveyor 1. It can be extended until it almost touches, eliminating gaps.

Even when the slat conveyor 1 is operated, the plate-shaped projections 20a of the wheel stoppers 2 and the plate-shaped projections 40a of the safety cover 4 pass each other, so that the wheel stoppers 2 do not collide with the safety cover 4.

[0020]

As described above, it is possible to completely prevent an accident in which the worker's foot or the like is caught in the downstream winding portion of the slat conveyor.
