Description

Detailed Description of the Invention [Industrial Technical 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 stacking items in bulk using a stacker or the like, a belt conveyor having a tripper is disposed at the rear end of the stacker, and the conveyed items 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 carry-in end of the stacker 1, and the articles to be conveyed from the belt conveyor 2 are transferred by the tripper 3 to the top of the boom conveyor 4 of the stacker 1. The objects to be conveyed are transferred onto the boom conveyor 4, and the objects are lowered onto the ground surface W and piled up in a pile 5 while the boom conveyor 4 is turned as appropriate and the stacker 1 and the tripper 3 are advanced as appropriate.

[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 be miniaturized by disposing a tripper at ground level and can supply objects to be transported to 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 vertical conveyor is provided, which has an opening for taking in 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 has a large number of buckets supported by the rotating table. The upper part of the vertical conveyor is arranged to deliver the objects to be conveyed to the boom conveyor, and the lower part is arranged to take in the objects to be carried in the inner cylinder, and is integrally connected with the inner and outer cylinders. It is something to do.

[Function] According to the above configuration, the tripper can be small because its discharge end is located near the ground surface, and the objects to be conveyed from the tripper are once delivered to the rotary table, and then sent to the boom via the vertical conveyor. transported to a conveyor. At this time, the vertical conveyor is supported by a rotary table and can rotate together with the boom conveyor, and since the vertical conveyor simultaneously rotates around the inner and outer cylinders at the lower end, it does not interfere with the handling of objects to be conveyed during the rotation.

[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 provided on the rotary table 9 so as to be movable up and down by a support pin 11, and a hydraulic cylinder 12 is provided.
The boom 10 is rotated.

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
Table portion 1 is rotatably provided to cover the lower ends of the inner tube 18 and outer tube 17 provided therein.
It consists of 9. Although not shown, the inner cylinder 18 is attached to the rotary table 9 and rotates as the rotary table 9 rotates. The objects to be conveyed are placed on the outer periphery of the inner cylinder 18.
8, and a scraper 21 for introducing the conveyed object into the opening 20.
is provided to partition the inner cylinder 18 and the outer cylinder 17.

A vertical conveyor 23 is provided within the inner cylinder 18 for supplying objects to be conveyed within the inner cylinder 18 onto a boom conveyor 22 provided on the boom 10 . Vertical conveyor 23
is a bucket type conveyor, and has a large number of buckets 25 connected by a chain in a case 24. A supply port 26 communicating with the opening 20 of the inner cylinder 18 is provided at the bottom, and a boom conveyor 22 is installed at the top. A discharge port 27 is formed at the carry-in end of the conveyor for transferring objects to be conveyed. Further, the vertical conveyor 23 is attached to the rotary table 9 so as to rotate together with the rotary table 9.

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

The conveyed object from the belt conveyor 2 is supplied from the discharge end of the tripper 15 onto the table section 19 between the outer tube 17 and the inner tube 18, and is moved as shown by the arrow in FIG. 3 by the rotation of the table section 19. and the inner cylinder 18
It is introduced into the case 24 of the vertical conveyor 23 from the opening 20 through the supply port 26 by the scraper 21 provided at the. The conveyed object introduced into the case 24 is transferred upward by the bucket 25 inside the case 24, is delivered from the discharge port 27 to the carry-in end of the boom conveyor 22, and is transferred from the carry-out end of the boom conveyor 22 to the ground surface W. As the objects are dropped, 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 vertical conveyor 23 also rotates, but at the same time the inner cylinder 18 also rotates, and the scraper 2
1 moves on the table portion 19, the transferred objects can be transferred smoothly.

[Effects of the Invention] As is clear from the above detailed description, 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 vertical conveyor, the large tripper like the conventional one is not required and the entire system can be made 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 vertical conveyor is vertical, even if it rotates with the boom, it rotates at the center of the rotary table, so objects to be transported can always be delivered to the boom conveyor in the same condition at any rotating position.
