Abstract

PURPOSE:To eliminate the need for dangerous work to improve the efficiency of cargo handling by changing a specified place in a hold up and down, side to side, back and forth in sequence to scrape up the chips, sucking up the chips by a vacuum type pneumatic conveyor, and convey the chips to the land by a belt conveyor. CONSTITUTION:At a specified place in a hold 55 of a chip carrier 1, one part of chips in the hold 55 are scraped together by a racking apparatus 54. The scraped chips are sucked up through a pipeline mounted on the scraping apparatus 54 by means of a vacuum type pneumatic conveyor to be discharged on a belt conveyor 3 on the deck 8. The chips are then conveyed to the land by the belt conveyor 3. These procedure and operation are performed repeatedly while the specified place for scraping the chips in the hold 55 is changed up and down, side to side, back and forth in sequence in the hold.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chip unloading method and apparatus for transferring chips in a hold of a chip ship to land by a belt conveyor on an upper deck.

[0002]

2. Description of the Related Art Conventionally, a chip installed on the upper deck of a chip ship grabs chips from the hold, drops them on a hopper installed on the upper deck, and unloads them on land via a belt conveyor. . In this case, in addition to the crane, it is necessary to collect chips with a bulldozer or human power inside the hold, and the work is dangerous, and the cargo handling is interrupted due to a strong wind, and the cargo handling efficiency is poor.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate dangerous work in the hold of a chip ship and to increase cargo handling efficiency.

[0004]

According to the present invention, (a)
At a predetermined place in the hold of the chip ship, a step of scraping out a part of the chips in this hold with a scraping tool,
(B) Using the vacuum type air conveyor to suck up the scraped-out part of the chips through the pipe line to which the scraping-out device is attached; and (c) the sucked-up part of the chips. Discharging to a belt conveyor provided on the upper deck of the ship, and transferring to the land via this belt conveyor, including predetermined positions in the hold in the up-down direction, left-right direction, and front-back direction of the hold. By repeating the steps (a), (b), and (c) with appropriate changes, all the chips in the hold can be transferred to the land, and the above-mentioned problem can be solved by the unloading method of the chip ship.

Further, it is preferable that the shaft 12 is constituted by, for example, a universal joint type flexible shaft so as to correspond to the inclination of the upper deck.

As shown in FIG. 1, a pair of rails 13, 1
Both ends are fixed on each carriage 4, 5 across the hatch opening 2 substantially parallel to each other at predetermined intervals. As shown in FIG. 3, the carriage 4 is provided with a vacuum type air conveyor including a vacuum pump 15 and a cyclone separator 16. As the vacuum type air conveyor, a well-known vacuum air conveyor is used as described in “Chemical Engineering Handbook”, page 833, published by Maruzen Co., Ltd. The outlet 17 of the cyclone separator 16 is located on the belt conveyor 3.

As shown in FIGS. 2 and 3, a pair of bearing blocks 18 and 19 are provided on the carriage 4. A shaft 22 provided with a pair of wire drums 20 and 21 is rotatably supported by bearing blocks 18 and 19. The shaft 22 is rotated by an appropriate drive mechanism 23 including an electric motor. On the dolly 5, a similar 1
A pair of bearing blocks, a shaft provided with a pair of wire drums, and a drive mechanism including an electric motor are provided.

As shown in FIGS. 2 and 4, the rails 13, 1
A traverse carriage 27 having a base plate 26 having wheels 24 and 25 is movably mounted on the table 4. Block 28 on base plate 26
To fix. Four protrusions 29, 29 ', 30, 30' are provided on each side of the block 28 in pairs. The wires from the wire drums of the trucks 4 and 5 are fixed to these protrusions. The drive mechanism 23 provided on the carriage 4 is operated to move the lateral movement carriage 27 to the right in FIG. The lateral movement carriage 27 is moved to the left by operating the drive mechanism provided on the carriage 5. In each drive mechanism, the shaft 22 is driven via a one-way clutch, and when one drive mechanism is operated, the other drive mechanism is not operated by the shaft 22.

As shown in FIGS. 2, 4 and 5, the U-shaped member 31 is fixed to the base plate 26 of the lateral movement carriage 27 and hangs down in the space between the pair of rails 13 and 14. Nesting tube 32,
A first nesting tube assembly 37 composed of 33, 34, 35, 36 is provided, and one end of the nesting tube 36 is fixed to the carriage 4. A seal, such as an O-ring, is secured to a predetermined end of each nest tube to keep the interior of the first nest tube assembly 37 airtight. One end of the nesting tube 32 is fixed to the U-shaped member 31. A second nesting tube assembly 41 comprising a curved nesting tube 38, a nesting tube 39 and a nesting tube 40 is provided.
Fixing one end of the curved nesting tube 38 to the U-shaped member 31,
The nest tube 32 is hermetically connected to the nest tube 32 by any suitable means.
A seal, such as an O-ring, is fixed to a predetermined end of each nesting tube to keep the inside of the second nesting tube assembly 41 airtight.

A wire drum device 42 equipped with a wire drum driven by a reversible electric motor is provided with a base plate 2 of a traverse carriage 27.
It is arranged almost at the center of one end of 6. The wire from this wire drum is attached to the attachment member 43 fixed to the tip of the nesting tube 40. The attachment member 43 engages with the tip of the nesting tube 39 when the nesting tube 40 is pushed into the nesting tube 39.

When the second nesting tube assembly 41 is in the contracted state, the reversing motor is rotated in one direction to feed the wire from the wire drum, and each nesting tube is sequentially lowered by gravity so that it can be arbitrarily extended. Try to occupy a position. The reversible motor can be rotated in the opposite direction, and the wire can move each nesting tube to the retracted position.

A horizontal carriage 27 is provided with a distribution cable 44 from a predetermined power source through rings 40, 47, 48 and 49 fixed to the tips of the respective nest tubes of the first nest tube assembly.
It is attached to the connector 45 provided on the base plate 26. The first conductor of the wiring cable is connected to the power circuit of the reversible motor. Connector 5 connected to the second conductor of the wiring cable
0 is provided on the base plate 26. The wiring cable 51 attached to the connector 50 is connected to the drive circuit of the screw 54 attached to the tip of the nesting tube 40 through the rings 52 and 53 fixed to the tips of the respective nesting tubes of the second nesting tube assembly. By rotating the screw 54 with a sharp tip, the chips in the hold 55 shown in FIG.
Facilitates wicking of tips into the telescoping tube assembly. Depending on the type of tip, a screw with a sharp tip or a propeller type screw 54 'or a bucket conveyor shown in FIG. 6 may be used instead of the screw with a sharp tip. Alternatively, these scraping tools may be removed, the tip of the second telescopic tube assembly may be opened, and the tip may be sucked up only by the action of a vacuum.

In FIGS. 2 and 5, the second nested tube assembly 41 is substantially orthogonal to the first nested tube assembly 37, but the second nested tube assembly 4 is shown.
Obviously, the second nested tube assembly 41 can be positioned at an appropriate angle with respect to the first nested tube assembly 37, as long as each nested tube of one can fall by gravity.

The bending portion of the curved nesting tube 38 is constituted by a well-known flexible tube (metal hose) described in "Mechanical Engineering Handbook" issued by the Japan Society of Mechanical Engineers, and the second nesting tube assembly 41 is in a contracted state. At times, the cart can be moved horizontally and the device of the invention can be moved over the adjacent hatch opening. However, the entire apparatus of the present invention may be moved to the adjacent hatch opening by a crane. Alternatively, the curved portion may be fixed to the U-shaped member 31 by screwing, and may be horizontally rotated when the second nested tube assembly 41 is in the contracted state.
