Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cargo handling device for supplying objects to a stacker for bulk loading, a loader for cargo handling on a ship, etc. This relates to a cargo handling device for transferring objects to a boom conveyor such as a stacker.

[Prior Art] Conventionally, when bulk stacking is carried out using a stacker or the like, a belt conveyor having a tripper is disposed at the rear end of the stacker, and the articles are supplied from the tripper to the stacker. That is, as shown in FIG. 1, the tripper 3 of the belt conveyor 2 is arranged behind the input end of the stacker 1, and the articles to be conveyed from the belt conveyor 2 are conveyed by the tripper 3 to the top of the boom conveyor 4 of the stacker 1. Then, the objects to be conveyed are transferred onto the boom conveyor 4, and while the boom conveyor 4 is turned as appropriate and the stacker 1 and the tripper 3 are advanced as appropriate, the objects to be conveyed are lowered onto the ground surface W and piled up 5.

[Problems to be Solved by the Invention] However, the boom conveyor 4 is located at a high position, and the inclination of the tripper 3 cannot be increased due to friction with the conveyed object, so the tripper 3 tends to be large and the belt conveyor 2 There is also the problem of increased power.

An object of the present invention is to provide a cargo handling device that can reduce the size of the tripper by arranging it at ground level, and can supply objects to be transported onto a boom conveyor such as a stacker.

[Means for Solving the Problems] The present invention provides a cargo handling device for transferring a conveyed object from a belt conveyor having a tripper to a boom conveyor such as a stacker whose tip can freely rotate horizontally. A rotary table is provided below the delivery end, an outer cylinder and an inner cylinder are provided to guide the conveyed object transferred onto the rotary table, and a scraper is provided between the inner and outer cylinders, and a scraper is installed in the inner cylinder. A steeply inclined belt consisting of a main belt conveyor and a presser conveyor, which forms an opening for taking the transported object guided by the boom conveyor into the inner cylinder, and which passes through the center of the rotating table of the boom conveyor and is supported by the rotating table. A conveyor is provided, and the upper part of the steeply inclined belt conveyor is arranged so as to deliver the objects to be transported to the boom conveyor, and the lower part is arranged so as to take in the objects to be transported in the inner cylinder, and is integrated with the inner and outer cylinders. It is characterized by being connected to.

[Function] According to the above configuration, the tripper is located near the ground surface and can be small, and the object to be conveyed from the tripper is once transferred to the rotary table, and is lifted almost vertically from the table by the steeply inclined conveyor to the boom conveyor. It will be handed over to. At this time, since the steeply inclined conveyor turns together with the rotating table of the boom conveyor, there is no problem with the turning of the boom conveyor.In addition, at the lower end of the steeply inclined conveyor, the inner and outer cylinders on the rotating table turn together, so the slope is steep. There is no problem in transferring objects to the conveyor.

[Embodiment] A preferred embodiment of the cargo handling device according to the present invention will be described below with reference to the accompanying drawings.

FIG. 2 shows an example of the stacker 1, in which a support body 8 is provided on a cart 7 that is movable along a running rail 6 provided on the ground surface W, and a support body 8 is mounted on the support body 8. A rotary table 9 is provided, and a boom 10 is mounted on the rotary table 9 so as to be movable up and down by a support pin 11, and the boom 10 is rotated by a hydraulic cylinder 12.

On the other hand, the support body 8 is provided with rollers 13 and 14, and the belt of the belt conveyor 2 is wound around the rollers 13 and 14 to form a tripper 15. The support body 8 is provided with a rotary table 16 for receiving objects to be conveyed from the output end of the tripper 15.
As shown in FIG. 3, this rotary table 16 includes an outer cylinder 17 attached to a support 8, and
An inner cylinder 18 provided therein, and a table part 19 rotatably provided to cover the lower end of the outer cylinder 17.
It is made up of. Although not shown, the inner cylinder 18 is attached to the rotary table 9 and rotates as the rotary table 9 rotates. An opening 20 is provided on the outer periphery of the inner cylinder 18 for passing the object into the inner cylinder 18, and a scraper 21 for introducing the object into the opening 20 is provided between the inner cylinder 18 and the outer cylinder 17. It is set up to separate.

A steeply inclined belt conveyor 22 is provided inside the inner cylinder 18 to transfer the objects in the inner cylinder 18 to the boom 10 side.

The steeply inclined belt conveyor 22 consists of a main belt conveyor 23 and a presser belt conveyor 24 provided to face the main belt conveyor 23, and transfers the object upward while being held between the conveyors 23 and 24. . This main belt conveyor 23 is a boom conveyor 25 provided on the boom 10.
The carry-in end and the belt are integrally connected in an endless manner. At the lower end of the steeply inclined belt conveyor 22, there is a scraping device 26 for supplying objects to be conveyed between the main belt conveyor 23 and the holding belt conveyor 24.
is provided, and the central portion is supported by a rotating table 9.

Next, the operation of the present invention will be explained.

The objects to be conveyed from belt conveyor 2 are transported by tripper 1.
5 is supplied onto the table part 19 between the outer cylinder 17 and the inner cylinder 18, and as the table part 19 rotates,
It moves as shown by the arrow in FIG. 3 and is supplied into the inner cylinder 18 through the opening 20 by the scraper 21 provided in the inner cylinder 18. The conveyed object supplied into the inner cylinder 18 is supplied between the main belt conveyor 23 and the holding belt conveyor 24 of the steeply inclined belt conveyor 22 by the scraping device 26, and the conveyor 23,
24 and transferred upwards, boom 1
0 is delivered to the carry-in end of the boom conveyor 25,
The objects to be transported are dropped onto the ground surface W from the unloading end, and the objects to be transported are piled up with an appropriate width by the rotation of the boom 10.

As the boom 10 rotates, the steeply inclined belt conveyor 22 also rotates, but at the same time, the inner cylinder 18 also rotates, so that objects to be conveyed can always be supplied to the steeply inclined belt conveyor 22 from the same position.

Incidentally, the steeply inclined belt conveyor 22 is an example in which two belt conveyors are provided facing each other, but one side of the belt conveyor is provided with a selvedge to form a box shape, and the other side presses the selvedge for sealing. Alternatively, the conveyed object may be wrapped and conveyed by one belt conveyor.

[Effects of the Invention] As is clear from the detailed description above, the present invention exhibits the following excellent effects.

(1) By installing the tripper on the ground level and connecting the boom conveyor and tripper with a steeply inclined belt conveyor, the large tripper unlike the conventional one is unnecessary and the entire system can be made more compact.

(2) Since the tripa is located at ground level, the belt conveyor for the tripa requires less power.

(3) The boom conveyor can be rotated freely.

(4) Since the main belt conveyor can be integrated with the boom conveyor, objects can be transferred smoothly from the steeply inclined belt conveyor to the boom conveyor.
