Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a hermetic closure of a splicing section from a -7j conveyor to a rotating/undulating conveyor.

[Background of the invention]

A stacker crane is used as the transfer section from one conveyor to the rotating and undulating conveyor.

In FIG. 1, the stacker crane 7 includes a pool 10 with a conveyor 4 mounted on a horizontally rotating frame 8, which can be raised and lowered vertically around an intersection 9, and is fed from a conveyor l supported diagonally by a running frame 11. This system receives the incoming cargo and drops the cargo from the upper end of the conveyor 4 into the yard and stacks it. This loading is carried out using the boom 10 when changing the position or height.
The position of the conveyor 4 is changed by raising and lowering or turning.

A chute 2 of the conveyor 1 is fixed to the upper end of a frame 11 that supports the conveyor 1, and the outlet of the chute 2 is positioned above the conveyor 4.

A skirt 5 is provided above the frame on the conveyor 4 side.

Such a stacker crane is shown on page 688 of the following document. Book title stacking blending

However, such canvas covers have a short lifespan.

[Purpose of the invention]

It is an object of the present invention to seal a transfer section to a rotating and undulating conveyor so as not to leak dust, and to prolong the life of the sealing means.

[Summary of the invention]

The present invention enables a hood to be freely taken up to a chute of one conveyor at a transfer point from one conveyor to another conveyor that undulates and turns, and a lid that can be freely slid is attached to this hood. A stopper is provided between the hood and the hood, and between the lid and the skirt of the other conveyor, and the rotation of the conveyor is controlled by the freedom of rotation of the hood, etc., and the ups and downs of the conveyor are controlled by the skirt pushing and pulling the lid with part of the stopper. The transfer part between the two conveyors is sealed without using the flexibility of the flexible abrasive, while allowing the conveyor to slide.

[Embodiment of the Invention] The present invention will be described below with reference to an embodiment shown in FIGS. 4 to 6. In FIG. 4, the lower end of the chute 2 is cylindrical, and a horizontal tube 12 is provided at the lower end. A cylinder 14 through which the cylinder of the chute 2 passes is provided at the center of the hood 13 and rests on the brim 12. For this reason, the hood 13 is free to horizontally pivot relative to the shoe 21ζ on the collar 12. A stopper 15 is provided in the middle of the hood 13 by bending it upward.

The stopper 15 is concentric with the cylinder 14.

A lid 16, 17 is placed on the top surface of the hood 13 so as to be able to slide freely. This lid 1 6 and 17 are actually 1
It is ring-shaped and has a hole in the center with a diameter slightly smaller than that of the stopper 15. A stopper 19 is provided on the end surface of the hole to protrude upward and downward. ts has been established. Stopper 18 can engage stopper 15 . A stopper 20 that projects upward is provided on the outer periphery of the lids 16, 17. The lid 16,17 rests on the outer edge of the hood 13.

The earthen wall of the skirt 5 is provided with a hole slightly larger than the diameter of the stopper 19, and the end surface of the hole projects slightly upward into a hemispherical shape, and a stopper 21.2 projects downward.
2 are provided. There is actually one stopper 21, 22, which is provided around the entire circumference of the hole and can be engaged with the stopper 191.

The upper surface of the hood 13 and the lids 16 and 17 are provided in an upwardly convex hemispherical shape. The radius of the radius is approximately equal to the radius of undulation of the boom 10 about the seat 2.

In this embodiment, when the boom 10 turns in the horizontal direction and the conveyor 4 turns, the skirt 5 also turns once at the same time. Hood 13, lid 16.17 is flange 12 of chute 2
Since the boom 10 is sequentially placed on the chute 2, the boom 10 can rotate around the chute 2.

Next, when the conveyor 4 is turned upside down from the state shown in FIG. 4 to the state shown in FIG. 5, the stoppers 19 of the lids 16 and 17 are pushed by the stoppers 19 of the skirt 5 and slide. Lid 1
The hood 131 is dyed up on the 7th side, and the lid 16th side is lowered. The stopper 18 on the lid 16 side is the stopper 1 of the hood 13.
5, so it won't fall off.

When the conveyor 4 rises from the state shown in FIG. 4 to the state shown in FIG. 6, the situation is reversed.

The same thing applies when the vehicle is turned while undulating.

In this way, when the conveyor 4 rises and falls, the lid 16°J7 slides and covers the space between the chute 2 and the skirt 5, so that no dust is generated from the core.

〔Effect of the invention〕

As described above, according to the present invention, in the sealing structure between transfers between conveyors, it is possible to seal while allowing the ups and downs and turns of the conveyor without using the flexible property.
This eliminates the need to use flexible materials that have a short lifespan, resulting in a longer lifespan for the sealing device.
