Abstract

PURPOSE:To miniaturize a tripper to make a cargo handling device compact as a whole, by arraning the outlet end of a tripper on a belt conveyor in the vicinity of the ground surface, and as well by connecting a vertical conveyor between the outlet end of the tripper and the inlet end of a boom conveyor. CONSTITUTION:Materials to be transferred from a belt conveyor 2 are fed from the outlet end of a tripper 15 onto a table section 19 between an outer cylinder 17 and inner cylinder 18 on a rotary table 16. Then, the materials are led into the inner cylinder 18 through an opening 20 by means of a scraper 21 disposed in the inner cylinder 18. Then, the mateials to be transferred are fed from an opening 20 into a casing 24 on a vertical conveyor 23 through a supply port 26 by means of scraper 21, and therefore are raised upward by a bucket 25 in the casing 24. Then, the materials to be transferred are shifted onto the inlet end of a boom conveyor 25 from an outlet port 27. Thereafter, the materials to be transferred are dropped onto the ground surface W from the outlet end of the boom conveyor 25. Further, the materials are stacked up in a suitable width due to the turning of the boom 10. Thereby, the tripper 15 may be miniaturized so that the device may be made also compact as a whole.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention 1] The present invention relates to a cargo handling device for supplying objects to a stacker for bulk loading, a ship loader for cargo handling on a ship, etc. - It relates to a cargo handling device for receiving and transferring objects from a conveyor to a boom conveyor such as a stacker.

[Technical background of the invention and its problems] Conventionally, when stacking items in bulk using a stacker or the like, a belt conveyor with a tripper on the right side is disposed at the rear end of the stacker, and the items to be transported 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 conveyed objects transported by 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 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 tripper 3 are advanced as appropriate.

However, since 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, there is a problem that the tripper 3 tends to be large and the power of the belt conveyor 2 also increases.

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

[Summary of the Invention] The present invention provides a cargo handling device for transferring conveyed objects from a belt conveyor having a tripper to a boom conveyor such as a stacker. The feature is that the output end and the input end of the boom conveyor are connected by a vertical conveyor, which eliminates the need for the conventional large tripper, making the entire system compact and reducing the power of the ground belt conveyor. This is what I did.

[Embodiments of the Invention] 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, which is an IC type and is a cart 7 that is movable on a running rail 6 provided on the ground surface W.
A support body 8 is provided above, a rotatable turntable 9 is provided on the support body 8, and a boom 10 is mounted on the turntable 9.
The boom 10 is provided to be movable up and down by a support bin 11, and is rotated by a hydraulic cylinder 12.

On the other hand, rollers 13.14 are arranged in stages on the support 8, and the belt of the belt conveyor 2 is wound around the rollers 13.14 to form the tripper 15.

A rotary table 16 for receiving objects to be transported from the discharge end of the tripper 15 is mounted on the support body 8. 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 inside the outer cylinder 17.
and a table portion 19 rotatably provided to cover the lower end of the outer cylinder 17. Although not shown, the inner cylinder 18 is attached to the rotary table 9 and rotates as the rotary table 9 rotates.

A frontage 20 is installed on the outer periphery of the inner cylinder 18 for passing the transported object into the inner cylinder 18, and a scraper 21 for introducing the transported object into the opening 20 is installed between the inner cylinder 18 and the outer cylinder 17.
It is set up to partition the space.

Inside the inner cylinder 18, a vertical conveyor 2 is provided to supply the objects to be conveyed in the inner cylinder 18 onto the boom conveyor 22.
3 is installed. The vertical conveyor 23 is a packet type conveyor, and has a large number of buckets 1 to 25 connected by chains in a case 24, and an inner cylinder 18 at the bottom.
A supply port 26 communicating with the frontage 20 is provided, and a discharge port 27 is formed in the upper portion for delivering the transported object to the carry-in end of the boom conveyor 22. Further, the vertical conveyor 23 is attached to the rotary table 9 so as to rotate together with the rotary table 9.

Next, a detailed explanation of the present invention will be given.

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. The vertical conveyor 23 is supplied from the frontage 20 through the supply L12G by the scraper 21 installed in the inner cylinder 18.
is introduced within the case 24 of. The objects introduced into the case 24 are transported upward by the packets 25 in the case 24, delivered from the discharge port 27 to the carry-in end of the boom conveyor 22, and from the discharge end of the boom conveyor 22 to the ground surface W. At the same time, 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, and at the same time, the inner cylinder 18 also rotates, and the scraper 21 moves on the table portion 19, so that conveyed objects can be transferred smoothly.

Incidentally, in the above embodiment, an example of a packet-type vertical conveyor was shown, but the present invention is not limited to this, and for example, a screw conveyor may be used. Furthermore, although the example of the stacker 1 has been described, it is of course applicable to a ship loader for shipping. Further, although an example is shown in which the rotary table 16 is provided for receiving and passing the conveyed objects from the tripper 15 to the vertical conveyor 23, this rotary table is not necessarily necessary. It is also possible to supply the liquid directly to the lower part of the case 24 and transport it on the vertical conveyor 23. In this case, by making the lower part of the case 24 rotatable, the boom 10 can be turned without any support.

[Effects of the Invention] As is clear from the above detailed description and Section I, the present invention exhibits the following excellent effects 1c.

(1) By installing 1~Lymph at the ground level and connecting the boom conveyor and 1~Lymph with a vertical conveyor, the large tripper unlike the conventional one is unnecessary and the whole can be made compact.

(2) 1~ Since the lymph is at the ground level, the belt conveyor of the tripper requires less power.

(3) The boom conveyor can be rotated freely.
