JPS59163221A - Vertical loader for object of definite form - Google Patents

Abstract

PURPOSE:To obtain a compact vertical loader by using a system in which when loading objects of a definite form, e.g., cement bags, etc., on the bottom of a ship in a wharf, the objects delivered by a boom are put on two adjacent vertical screw conveyers in a riding manner and then lowered. CONSTITUTION:A vertical loader 1 for objects of definite form 4 is set adjacently without two vertical screw conveyers 2 being overlapped, and a cover 3 to cover the whole of the loaders is provided. The cover 3 is provided with guide faces 5a and 5b for the objects of difinite form 4. The conveyer 2 is rotatably hung down from the tip of a boom 8 supported by the loader body and moving in a tilting and expandible manner. When loading objects on the bottom of a ship in a wharf, since the conveyer 2 is turned in the opposite direction with the same speed, the objects 4 delivered by the boom 8 are directed into the cover 3 through the upper opening 11, placed on the two conveyers 2 in a riding manner, lowered under guidance of the guide face 5a of the cover 3, and carried out from the lower opening 12 to the lower roller 15.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vertical cargo handling device, and more particularly to a vertical cargo handling device for a compact, regular-shaped object that can unload and unload cargo at any speed.

When loading fixed objects such as cement bags onto the bottom of a ship moored on a quay, a loader that runs on the quay is used. This loader has a structure in which a number of conveyors are connected, and a vertical unloading device is attached to the last stage at the tip of a boom that is supported by the loader body so as to be able to move up and down and extend. Conventionally, vertical spiral chutes, inclined con-hairs, vertical pinch con-hairs, etc. have been employed as this unloading device. Since the vertical spiral chute has a spiral chute, a fixed object placed into the chute will slide down due to its own weight. In this case, not only is it impossible to adjust the speed at which the shaped object slides down, but there is also the drawback that the preceding shaped object gets caught in the chute, clogging the chute. Since a limit is naturally imposed on the angle of inclination of the inclined conhair, the above-mentioned inclined conhair from the tip of the boom to the bottom of the ship becomes extremely long and the weight of the equipment increases. Also, if you make the length appropriate, it will not reach the bottom of a large ship.
It has the disadvantage that an auxiliary chute must be installed between it and the bottom of the ship. Vertical pinch conveyors transport fixed objects to the bottom of the ship by sandwiching the left and right sides of the objects between two vertical and parallel conveyors.Compared to the above-mentioned unloading device, one more conveyor is required, resulting in an increase in the weight of the equipment. There are some drawbacks. Each of the above unloading devices is only capable of unloading,
The disadvantage is that unloading work cannot be done.

Incidentally, unloading devices include a porta-pull belt conveyor with an addition, a crane, etc., but each of these devices must be installed separately from the above-mentioned unloading device, which is both inefficient and uneconomical.

The present invention was made in order to solve the above-mentioned drawbacks, and it is possible to adjust the speed of conveyance of a fixed object to the bottom of a ship, and it does not require a large space, and the fixed object can be loaded and unloaded using the same device. The purpose is to provide vertical cargo handling equipment.

The feature is that two adjacent vertical screw conveyors are suspended from the tip of one boom, which is supported by the loader body in an upward and downward and telescopic manner, and these two screw conveyors are covered with a lid. A cover is installed, and the upper part of the cover has an upper opening that opens toward the boom side, and the lower part has a lower opening that opens in the opposite direction to the upper opening, and the two vertical screw connecting hairs are arranged opposite to each other. A vertical cargo handling device for a shaped object, which is capable of lowering and raising a shaped object mounted on two screw conveyors so as to be in contact with a guide surface in a cover by simultaneously rotating the objects in the directions. That's what I did.

Hereinafter, the present invention will be explained in detail based on examples thereof.

FIG. 1 shows a sectional view of essential parts of a vertical cargo handling device 1 for fixed objects according to the present invention. As shown in FIG. 2(a), two vertical screw conveyors 2 are arranged adjacent to each other without overlapping, and a cover 3 is attached to cover the entire conveyor. The cover 3 has a gourd-shaped cross section, and guide surfaces 5a and 5b for the shaped object 4 are formed in the recessed portions, as shown in FIGS. 2(a) and 2(b). The two vertical screw conhairs 2 have a screw 7 fixed to a screw shaft 6 and have a fixed pinch angle α, and are attached to the tip of a boom 8 that is supported by a loader body (not shown) and moves vertically and retractably. The vertical cargo handling device 1 is rotatably suspended from the section 9 via a pin IO. Furthermore, the cover 3 is provided with an upper opening 11 that opens toward the boom 8 side in the upper part 3a, and a lower opening 12 that opens in the opposite direction to the upper opening 11 in the lower part 3b. There is.

Reference numeral 13 designates a motor for simultaneously rotating the two vertical screw conhairs 2 in opposite directions, and is connected to the motor 9 via a bearing at the lower end of the screw shaft 6, and at the upper end of the screw shaft 6. is rotatably supported by a bearing or the like at the upper end of the cover 3.

With the above configuration, unloading and unloading operations can be performed as follows.

First, let's talk about the unloading work when loading a regular object 4 onto the bottom of a ship moored at a quay. Boom 8 moved to a predetermined position and supported
The operator looks up and expands and contracts the fixed object 4 to place it at the desired loading position. Since the vertical screw conveyor 2 is suspended by a pin 10 at the tip of the boom 8, it is naturally held vertically just above the loading position. Then, the screw conveyor 2 moves at the same speed as the arrows 14 opposite to each other.
Since the fixed object 4 conveyed by the boom 8 is introduced into the cover 3 through the upper opening 11, as shown in FIG. The cover 3 is placed on the two screwcon hairs 2 and comes into contact with the guide surface 5a of the cover 3. and,
This fixed object 4 is guided while in contact with the guide surface 5a,
As shown in FIG. 1, the fixed object 4 that has reached the lower opening 12 is lowered by the lower roller due to the rotation of the screw 7 in the direction of the arrow 14. When the unloading work is completed, the boom 8 is moved vertically and telescopically, and the vertical cargo handling device 1 is moved from inside the ship to a predetermined retreat position.

The unloading operation is the same as in the previous example, and when the vertical cargo handling device 1 is set at a predetermined position, the fixed object 4 on the bottom of the ship (not shown) is mounted on the lower roller I5 and introduced into the lower opening 12, and an arrow opposite to that described above occurs. As the vertical screw conveyor 2 is rotated in the direction 16, the shaped objects 4 are drawn into the cover 3 and the second
It is in contact with the guide surface 5b shown in Figure (b). Then, the shaped object 4 rises by the same operation as described above, and the upper opening 1
1 to the conveyor on the boom 8.

In the above-mentioned unloading and unloading work, the screw conhair 2 may be rotated by a separate motor, but if it is driven by a single motor via a speed reducer etc., the fixed-shaped object can be moved in a constant posture. can be done. Further, by changing the drive speed of the motor, the conveyance speed of the fixed object can be changed, and the operation can be flexibly performed depending on the amount of cargo handled and the cargo handling operation.

As described in detail above, the present invention provides two adjacent parts at the tip of a boom that is supported by the loader body in a vertically extending and retractable manner.
A vertical screw conveyor for books is hung, a cover is attached to cover these two screw conveyors, and the upper part of this cover is provided with an upper opening that opens toward the boom side, and the lower part is opposite to the upper opening. By providing a lower opening opening in the direction of , the two vertical screw conveyors are rotated simultaneously in opposite directions, so that the shaped object straddles the two screw conveyors and is in contact with the guide surface inside the cover. Can be lowered and raised. Therefore, not only can unloading and unloading operations be performed using the same device, but also the raising and lowering speeds of fixed objects can be easily changed by adjusting the rotational speed of the vertical screw conveyor, and It can be a compact vertical cargo handling device.
